2What Is MEPro?
- ME Consultant Professional (MEPro) is a
program written to help you with planning,
estimating, and programming for CNC machining
centers and lathes. - MEPro is a fast and accurate alternative to
stacks of reference books, hours of Internet
searching, and repetitive, error-prone manual
calculations. - MEPro is extremely easy to use. It gives you a
massive amount of useful, well-organized
information in exchange for a very small amount
of your time. - MEPro is designed to be equally useful to users
of the inch or metric system. - All functions are accessible through a dropdown
menu in the Machining Calculator window, or a
right-click context menu available in any window. - The program should run fine on any 32-bit
Windows system. Your screen needs a minimum
resolution of 1024 x 768 pixels for best display
of all the available functions.

data. - Very little typing is required for efficient use
- you change one value and all the others update
automatically.
6The Job Planner
Summary Window
Viewer Window
Job Plan Window
- The Job Planner takes data from the Machining
Calculator and creates a Job Plan for your
operation. - The data for each machining sequence, and all
the totals to that point, are displayed in the
Viewer and Summary Windows, respectively. - Add or remove a Tool - the Viewer and Summary
Windows update instantly. - Change a Tool Diameter - machining data for
that tool is recalculated. The Viewer and
Summary Windows update. - Add some Passes, change the Material, decide to
run the job on a different Machine - do whatever
- a click or two with the mouse and the entire
job recalculates!
7The Machining Calculator and Job PlannerWork
Together To Make Planning A Breeze!
The windows fit without overlapping on a screen
having a resolution of 1024 x 768 or better.
8The Material Planner
- The Material Planner instantly calculates the
weight, volume, and cost of the material you'll
need for an upcoming job. - It comes with a large database of the materials
you're most likely to need. Adding more
materials is easy, and so is adjusting the unit
cost of a material in response to changing market
conditions. - You can enter data in inches, feet, millimeters,
or meters - or even switch around as you work! - Once you've made the calculation, the Material
Planner can post it to the Job Planner.
9Thread DataMore Than 1200 Sizes
- This is the information you're most likely to
need for manufacturing threaded components. - An invaluable reference for programmers,
inspectors, machinists, and design engineers. - The Tap Drill Guide automatically shows you the
best drills for the thread you're displaying.
Form taps are supported for most thread types. - An Info Window has application and plating
guidelines, along with other useful information,
for each thread type. - Infeed calculations for manual machinists.
- Inch or metric display.
- Prints a complete report for each thread size,
which is especially useful to machinists and
inspectors.
10The Drill Depth Calculator
- Calculating the depth to feed a center drill,
spot drill, or countersink to machine a specific
chamfer diameter on the face of a part is one of
those recurring time-wasters that every
programmer and machinist is familiar with. - The Drill Depth Calculator turns this into a few
seconds' work. - It can also tell you how deep to send a twist
drill to machine a full-diameter hole of a
specific depth. -
11The Surface Finish Calculator
- The main influence on surface finish,
particularly in turning, is the combination of
tool radius and feedrate. - The Surface Finish Calculator gives you the
theoretical feedrate needed to achieve a specific
surface finish when using a given tool radius. - CNC programmers and machinists need a reliable
tool to make this calculation, so that they don't
feed too fast and make unacceptable parts, or
feed too slowly and increase costs.
12The Machining Data Editor
- The Machining Data Editor lets you edit the data
used by the Machining Calculator and Job Planner. - You can modify, add to, delete from, or
rearrange the data. - A customer calls and needs a rush quote, an old
job but with a material change. He says the new
material has historically run well at 20 higher
speed and 10 higher feed than the old one. - You need to define that new material, and fast.
- Its so easy - a quick series of mouse clicks
followed by typing in a name for the new
material. -
- The supervisor tells you the normal machine for
that job is down. It will have to run on an
older model, a much slower one. How much will
that add to the cost? -
- Three clicks in the Job Planner to recalculate
the old job for the new material on the
substitute machine.
13The Machine Specifications Editor
- The Machine Specifications Editor lets you
- define and modify six key performance
- characteristics for each of your machine
- tools. These values are used to optimize
- output from the Machining Calculator and
- Job Planner.
14The Configuration Window
- This is where you decide how you want MEPro to
be set up when it starts. - You can opt for a full-blown inch or metric
setup. - Do you want tooltips turned on? They're great
for learning the program, but you might want them
turned off later. - How many decimal places to display?
- What are your rapid clearances? There are safety
and efficiency considerations. - What spindle efficiency rating do you want power
calculations to be based on? - Do you want a "canned" set of labels for the
printed Job Plan Report?
No matter how you have things set up in the
Configuration Window, you can change the settings
around as you work. They just won't be saved for
next time unless you save them in the
Configuration Window.

17Getting Started With MEPro
- The first time MEPro is run, this window will
pop on your screen. Youll have to select either
inch or metric as the default startup mode.
Dont worry about locking yourself in to one
system or the other here its easy to
reconfigure MEPro at any time, or even to switch
back and forth between measurement systems as you
work.
If you go with the inch system, a machining data
file will be created with speed data listed as
surface feet per minute and feedrate data listed
in inch units. This file will be named
MEInchData.dat. If you select the metric system,
the data file will have speed data listed as
surface meters per minute and feedrate data
listed in millimeter units. It will be named
MEMetricData.dat.
18The Configuration File
- A configuration file, me.ini, will also be
created the first time MEPro runs. It contains
startup options for many MEPro functions. The
initial values assigned to me.ini are intended to
be suited to the measurement system you selected
(inch or metric). Theyre all very easy to
change to meet your needs. - All data and configuration files are located in
the same directory as the main program file. Any
of them that can't be found when the program is
run will be recreated by MEPro (with default
values).
19The Machining Calculator
- When MEPro is run, the first thing youll see is
the Machining Calculator. It starts up with some
arbitrary selections - Cast Aluminum, a
pre-defined CNC machine called Machining Center
1, and a High Speed Steel (HSS) Spot Drill with a
diameter of .500, set to drill .100 deep.
20What The Machining Calculator Does
- The Machining Calculator suggests speed and feed
values for a specific combination of cutting tool
and workpiece material. Twenty tool types and
twenty material types are defined initially. You
can easily create as many additional materials as
you need. - In addition to cutting parameters, the Machining
Calculator displays cycle times and power
requirements for your proposed operation. - The Machining Calculator requires very little
user input. Much like a spreadsheet, when you
change one value, all the dependent values are
recalculated and redisplayed. You can do what
if experiments very easily and plan cutting
operations that make the most of your expensive
tools and machinery.
21A Bit Of Caution
- Workpieces can be held securely or poorly.
- Machine tools vary widely in their ability to
take a cut. - Some workpieces are more rigid than others.
- Sometimes cutting tools are used
inappropriately. - Some cutting tool designs work better than
others. - Some cutting tools are sharp, others are dull.
- Some cutting tools are rigid, others aren't.
- Unanticipated problems can crop up.
- There's no way for the Machining Calculator to
factor in non-optimal conditions without your
help. If your setup isnt rigid or your
workholding is inadequate, serious problems can
result. If your cutting tool isnt in good
condition, or is inappropriate for the operation,
you could see unexpected results. - You, the user, are completely responsible for
the results of applying the recommendations made
by the Machining Calculator.
22Getting Started With The Machining Calculator
- Select a Material Type, Machine, and Tool from
the dropdown lists at the top of the window. The
Machining Calculator displays the suggested
spindle speed (RPM) and feedrate (IPT, IPR, IPM)
for the current combination of Tool and Material,
along with the material removal rate (MRR) and
machine power (HP) required. - If you want accurate information about cycle
times, input the quantity (Hole Qty) and depth of
holes (Hole Depth) or the quantity (Pass Qty) and
length of passes (Pass Length). - Practice changing some of the displayed values
to see the effect on others. Change the Material
Type and watch practically everything else
change. Move the Tool Diameter scrollbar and see
how many other values change in response. Think
about the reasons for those changes. - Thats really about all you have to do to get a
wealth of information from the Machining
Calculator. There are some options well need
look at, but nothing is really complicated about
using it.
23Entering Data
- To enter a value, just type it into the
appropriate edit box and left-click anywhere
outside that edit box. Instead of clicking, you
can also press the Enter key or Tab key. The
Enter key inputs the value that's currently
visible in the active edit box. The Tab key
inputs the value, then advances the focus to the
next relevant edit box. - Numerical data can be input in several formats.
If you want to enter a value of .250, type in
.250 or any numerical expression that evaluates
to .250 (1/4 or 1-3/4 or .5.5 are some
examples). - Because the program is designed for
manufacturing, you can also input an expression
with one space (for example, you can specify a
drill diameter of 1 3/16 and MEPro will convert
it to 1.1875). Remember, only one space is
allowed in your expression. - MEPro wont let you make many mistakes.
Non-numerical input wont be accepted. If
numerical input isnt within the allowable range
for a particular characteristic, it will be
adjusted to the closest-possible legitimate
value. For example, the diameter range for
carbide twist drills is .015 to .750. Values
smaller than .015 will be adjusted upward, and
values larger than .750 will be adjusted downward.
24Materials
- MEPro comes with extensive machining data for
twenty materials commonly used in manufacturing
operations. This data is the result of averaging
recommendations from a large number of technical
organizations and cutting tool manufacturers. - These materials, with perhaps some "tweaking" to
suit specific needs, will probably be enough for
most users. Later in the tutorial we'll see how
easy it is to modify the machining data or create
entirely new materials.
25Tools
- MEPro can make machining calculations for twenty
different types of cutting tools. These tools
are commonly used on CNC machining centers or
lathes, and most of them show up on both. - Five of the tools (those with an "HP" prefix)
are included to let you define cutting data for
some of today's high-performance tool geometries
and coatings. As we'll see later, they can
easily be configured to reflect their enhanced
cutting capabilities.
26Cutting Speed
- Changing cutting speed values causes
recalculation of - machining time, material removal rate, and power
- requirements
- RPM - Revolutions Per Minute
- SFM - Surface Feet Per Minute
- SMM - Surface Meters Per Minute
- RPM Limit - A means of limiting the maximum
revolutions - per minute displayed or used in
calculations. All machines - have an absolute maximum RPM, and some tools or
setups - have a maximum safe RPM.
-
- Spindle works like the spindle override on a
CNC - machine.
27Feedrates
- Changing feedrate values causes recalculation of
- other feed outputs plus machining time,material
removal rate, - and power requirements
- IPT - Inches Per Tooth (Chip Load)
- MPT - Millimeters Per Tooth (Chip Load)
- IPR - Inches Per Revolution
- MPR - Millimeters Per Revolution
- IPM - Inches Per Minute
- MPM - Millimeters Per Minute
- Feed works like the feed override on a CNC
- machine.
- Reset Sets Feed to 100.0
- Becomes pink when Feed is over 101.00, and blue
28Cut Variables
- Length, Depth, and Clearance values affect
machining time. - Cut Depth and Cut Width values affect material
removal rate, - power requirements, and end milling speeds,
feeds, and - machining time.
- Pass Length - turning and milling tools
- Hole Depth - holemaking tools
- XY Clearance - rapid clearance for milling tools
- Z Clearance - rapid clearance for holemaking
tools - XZ Clearance - rapid clearance for turning tools
- Cut Depth - axial depth of cut for milling tools
- radial depth of cut for
turning tools - Cut Width - radial depth of cut for milling
tools - radial depth of cut for
boring tools
29Cutting Tool Characteristics
- Flutes - holemaking and end milling tools
- Inserts - face mills and turning tools
- A change causes recalculation of feed outputs,
machining times, material removal rate, and power
requirements - Tool Diameter - holemaking and milling tools
- Turn Diameter - turning tools
- A change causes recalculation of speed and feed
outputs, machining times, material removal rate,
and power requirements. - When the diameter of an end mill or face mill is
reduced, Cut Depth and Cut Width may also be
reduced.
30Machining Calculator Options
- Inch - inputs and display in inch units
- Metric - inputs and display in metric units
- Tips - Turns the Machining Calculator tooltips
on or off. - Sticky Data - When checked, saves the most -
recent data for each tool type, so you can go
back to a previous tool without having to input
all the cutting conditions again. When
unchecked, tool data is reset to defaults each
time you select a new tool. - Mill Radius - When checked, adds the radius of a
milling tool to the pass length for cycle time
calculations. - Radial Feed - When checked, applies a radial
chip thinning factor to the feedrate calculation
for face mills and end mills when the Cut Width
is less than half the Tool Diameter. - Decimals - Lets you specify how many decimal
places to display for some of the machining data.
31Machining Time
- Minutes Per Hole - Shows the time in minutes per
hole or pass. - Display only.
- Minutes Total - Shows total time in minutes for
all holes or passes. - Display only.
- Hole Qty holemaking tools
- Pass Qty turning and milling tools
- Change causes recalculation of Minutes Total.
- Maximum Qty is 10,000
32Machining Power
- HP - machine power (horsepower) required to
perform the defined operation. Display only. -
- KW - machine power (kilowatts) required to
perform the defined operation. Display only. -
- Both measures are based on the material removal
rate for the active material. -
- MRR - material removal rate - volume of
material, expressed as cubic inches or cubic
centimeters, removed per minute with the
currently defined operation. Display only. - Spindle Efficiency
- Change causes recalculation of power
requirements.
33Tap Pitch Selector
- These controls are enabled when a Tap is the
active tool type. The screenshots show some of
the tap pitch options available in MEPro. - When the TPI option button is selected, the
values represent threads per inch. When the MM
option is selected, the values represent the tap
pitch in millimeters. - TPI and MM are both usable whether you're
working in Inch or Metric mode. If you're
working in Inch mode and need data for an M8-1.0
tap, for example, just select the MM option
button, then 1.0 from the pitch selector. Click
on the Metric mode option button, input 8.0 into
the Tool Diameter edit box, then switch back to
Inch mode. Everything will be converted for you. - Of course, you could stay in Inch mode the whole
time and just input the expression 8/25.4 into
the Tool Diameter edit box to get the same result.
34Opening The Job Planner
- When the Job Planner is first opened, what you
see are three new windows arranged around the
Machining Calculator. There aren't any numbers
showing in these three windows, except in the
Machine , Eff , Setup, and Tool Sec boxes. - The values in those edit boxes are taken from
the MachineSpecsData.dat file, where the
performance characteristics of your machine tools
are defined. - Machine - hourly rate for the active machine
- Eff - overall efficiency factor for the active
machine - Setup - default setup minutes for the active
machine - Tool Sec - tool change seconds for the active
machine - Select a different Machine in the Machining
Calculator and you'll see some of these values
change in the Job Planner.
35Adding a Sequence
- What we're trying to do here is have you tell
the Machining Calculator what kinds of tools and
cuts you want to have in your proposed job, so
that it can figure out all the machining
parameters and send them to the Job Planner,
which will keep track of and display everything.
If you want a printed report after everything
looks good, you can have that too. - There's already a machining operation defined in
the Machining Calculator (I'll refer to a unique
machining operation as a"sequence" after this).
It's the one that shows when you first run MEPro,
a Spot Drill going .100 deep. - Start out by clicking the Seq button in the
Job Planner and see what happens. - The machining data for the sequence is posted to
the Viewer Window, while current time and cost
totals appear in the Summary Window. The Spot
Drill is now shown as the Active Sequence
(sequence 1) in the Job Planner, - Select a different material in the Material list
of the Machining Calculator and watch what
happens to your machining times and summary
values. It's that quick and easy to play what-if
games with different materials, whether you've
defined one sequence or a hundred.
36Job Planner Commands 1
- Active Sequence - this can be either the
sequence you've just added or the sequence you've
chosen to make active, perhaps for editing or
deletion. - To change the Active Sequence, you can either
select a new one from the dropdown list in the
Job Planner, or click on the ID number of the
desired sequence (leftmost column) in the Viewer
Window. - Notes - you can insert a descriptive note
for each sequence. The note will display on the
printed report. - Active Material - this is the material upon
which the current Job Plan machining calculations
are based. - To change the Active Material, select a new one
in the Material dropdown in the Machining
Calculator. The Job Plan will instantly
recalculate. - Active Machine - this is the machine upon which
the current Job Plan non-machining calculations
are based. - To change the Active Machine, select a new one
in the Machine dropdown in the Machining
Calculator. The Job Plan will instantly
recalculate.
37Job Planner Commands 2
Move - this is used to rearrange the order of
your defined sequences. Say you had five
sequences defined, and wanted to move sequence 5
up to become sequence 3. Type 5 in the From box
and 3 in the To box, then click on the green
button (it will be green if you have more than
one sequence defined). Tips - this turns the
tooltips on and off for the Job Planner. Win
Sync - when this is checked, all four windows
minimize as a group rather than individually.
When they're hidden, some external applications
allow them to maximize as a group and some don't.
38Job Planner Commands 3
These values can be modified freely. Each
change results in an update of the Summary Window
data. Machine - the Active Machine hourly
rate Eff - Active Machine efficiency ("fudge
factor") Material - unit material
cost Setup - Active Machine setup
minutes Tooling - tooling and fixturing cost
for the job Tool Sec - Active Machine tool
change seconds Process - job process cost
(plating, heat treat, etc.) Part Sec -
part change seconds per part Lot Size - lot
size for the job Extra Min - extra
minutes per part (for any purpose)
39Job Planner Commands 4
Seq - deletes the Active Sequence. Seq
assigns the data currently displayed in the
Machining Calculator to a new sequence. Tool -
subtracts one from the current number of tool
changes - useful if you're doing more than one
sequence with the same tool and don't want the
extra tool change seconds added to the
total. Tool adds one to the current number of
tool changes. Edit lets you edit any value in
the Active Sequence. Update recalculates the
Job Plan after using Edit.
40Editing A Job Plan Sequence
You can change any value in a previously-defined
sequence. Make the sequence you want to edit
the Active Sequence. Click the Edit button. It
will turn pink as an indicator that you're in
edit mode. All the machining data for the
Active Sequence will be pasted into the Machining
Calculator. Using the Machining Calculator,
make any changes you like to the values. Click
Update to recalculate the Job Plan and exit edit
mode. You can exit edit mode without saving
changes by clicking the pink Edit button.
41Job Planner Commands 5
Feed - reduces all feedrates in the Job Plan by
5. Feed increases all feedrates in the Job
Plan by 5. Spindl - reduces all speeds in the
Job Plan by 5. Spindl increases all speeds
in the Job Plan by 5. F-100 sets all feed
overrides in the Job Plan to 100. S-100 sets
all speed overrides in the Job Plan to
100. Calc forces a recalculation of the Job
Plan. Zero subtracts the Active Sequence
values from the Summary (it "zeros out" the
sequence). Clicking the Zero button a second
time restores the values. This can be useful for
"what if" experiments.
42Job Planner Commands 6
Notes opens the Notes Window, where you can
define up to twelve sets of notes for the heading
of a Job Plan Report. Hide minimizes the Job
Plan Window. If Win Sync is checked, all Job
Planner windows and the Machining Calculator will
be minimized. Save saves the Job Plan data as a
.csv file, which can be easily imported into your
favorite spreadsheet program for use with custom
report formats. Clear clears the Job Plan from
memory. Load loads a previously-saved Job Plan
(.csv file) into memory. Close closes the Job
Planner.
43Adding Notes To The Job Plan Report
Click Here To Add A Label
- After the sequences are defined, you might want
to add some descriptive notes before printing or
saving a report. - The Notes Window has space for up to twelve
labels and associated notes, which will be
displayed at the top of the printed Job Plan
Report. - Labels and notes may be edited freely, but the
total number of characters for a label and its
companion note cant exceed fifty. - To create or edit a label, click in the
background area just above the appropriate note
box.
Clear Data erases the notes but not the
labels Clear All erases everything Close Window

46The Job Plan Report
- This job has twenty-two tools.
- The labels and notes from the Notes Window are
at the top. - The machining data from the Viewer Window is in
the middle. - There's a complete Summary at the bottom.
47The Material PlannerGetting Started
The first time the Material Planner is run, it
generates a data file. Depending on your
configuration, the density values in the file
represent either pounds per cubic inch or grams
per cubic centimeter. If configured for inch
data, the file will be named WeightUSData.dat. If
configured for metric data, the file will be
named WeightMetricData.dat. Materials can be
added to the file by opening it in a text editor
like Notepad. Cost information for each material
type is maintained in the same file. You can
also modify and save material cost information
directly from the Material Planner.
48The Material Data File
The format of the data file is simple. Here's a
typical line Aluminum,.0975,.50 As this
line was taken from WeightUSData.dat, it says
that the material named "Aluminum" has a density
of .0975 pounds per cubic inch, and costs fifty
cents per pound. The metric equivalent, taken
from WeightMetricData.dat, would be
Aluminum,2.6988,.50 It says that the
material named "Aluminum" has a density of 2.6988
grams per cubic centimeter, and costs fifty cents
per kilogram. You can modify the density and
cost values as needed. If you add a new
material, be sure to include a number for the
cost, even if you don't plan to use it (.50 would
be fine).
49Materials And Shapes
- Choose a material category by clicking on the
appropriate option button (Metal, Wood, Plastic,
Other). Next, select a specific material from
the dropdown list. - The density will be displayed to the right, in
pounds per cubic inch or grams per cubic
centimeter, depending upon the active input mode.
The density value can only be modified by
editing the data file. - Select a shape from any displayed in the frame
at the left edge of the Material Window. -
- Depending on which shape you pick, you'll have
to furnish from one to six dimensions before
volume, weight, and cost calculations can be
made. The labels above the input boxes will
change to fit the requirements of the active
shape. - In the case of Fabrications (Pipe, Angles,
Channels, I-Beams), you'll have to select a size
from the dropdown list. Except for the length,
all inputs for the selected size will be entered
automatically. These values represent industry
standard dimensions and can't be modified.
50Material Units
- Dimensions can be entered in any combination of
Inches, Feet, Millimeters, and Meters. - The current input mode is displayed at the top
of the Inputs Frame. - You can enter everything in the same mode, or
switch around as you dimension a shape.
Selection of the input mode is done in the
Options Frame at bottom-center. - As an example, if you had round stock with an
outside diameter of thirty millimeters and a
length of ten feet, you could input the diameter
in Millimeters, then switch to Feet for the
length. - All values display in the currently selected
mode.
51Material Planner Inputs
When you select a shape, two or more of the
labels above the six edit boxes change to
indicate the inputs required. As usual,
left-clicking the mouse outside of an edit box
inputs the value youve just typed in. The Enter
key or Tab key can also be used to input the
data. Additionally, the Tab key shifts focus to
the next required edit box for further
input. For shapes where they are geometrically
possible, internal and external fillets are
established and initialized to zero. They're
skipped in the first run-through - you can go
back and change their values later if you want
to. Remember that you can use numerical
expressions for your inputs, so 1.500 is the same
as 11/2 or 1 1/2 Note that Feet is not the
same thing as feet and inches - to input 1 foot 6
inches while in Feet input mode, you could enter
1.5 or 16/12 or 1 6/12 or 1(6/12), but not 1
6. Inputs that are recognized as being
geometrically impossible are adjusted up or down
as appropriate.
52Material Planner Outputs
- Once you've input all the required dimensions,
Volume and Weight will be calculated and
displayed. Cost Data will be displayed also if
you have that option enabled. - You can change the dimensional values, quantity,
and input mode at will to evaluate the effect on
volume, weight, and cost. - Changing the Material Type will cause a
recalculation and redisplay of volume, weight,
and cost. - Changing the Material Shape clears all boxes -
you start from scratch. - Outputs in Inches or Feet mode are in cubic
inches (volume) and pounds (weight). - Outputs in Millimeters or Meters mode are in
cubic centimeters (volume) and kilograms (weight).

54Material Planner One-Shot Calculations
There are two options for making simple one-shot
calculations. If you know the volume of an
object and the material density, selecting the
User Input Volume mode lets you input the volume
and calculate the weight. If you know the
weight of an object and the material density,
selecting the User Input Weight mode lets you
input the weight and calculate the volume.
55Material Planner Tricks
Some of the limits (maximum length or maximum
quantity, for example) are designed to keep
things manageable. An item that weighs 50,000
pounds is fine, but displaying the total weight
of two million of them wouldn't be. In some
cases it's possible to "fool" the program. For
example, if the length limit of 300 inches (25
feet) is inadequate for a specific calculation -
say, 5000 feet of wire - a workaround would be to
enter the wire diameter, then select Feet mode
and enter 25 for the Length. Input the
expression 5000/25 into the Quantity box, and the
correct Total Weight will be displayed. This
method should work equally well with most of the
other shapes.
56A Lot Of Thread Data
- The Threads Window displays detailed dimensional
information for more than twelve hundred common
screw threads. - There's a sophisticated Tap Drill Guide with
more than seven hundred twist drill sizes. Form
tap drill sizes can be displayed for many of the
thread types. - An Info Window has application and plating
guidelines and additional geometric information
for each thread type. - Lathe infeed calculations are available
for manual machinists. - You can Print a detailed report for each thread
size. - The display can be toggled between Inches and
Millimeters.
Tracking down thread data is one of the biggest
time-wasters in manufacturing. Manual
calculations based on partial data are likely to
cause expensive errors. It's all here, fast and
accurate.
57The Tap Drill Guide
75 Thread Selected
When you select a Thread Size, the minimum minor
diameter (internal) is checked and the first
drill in the database which is at least that
large is positioned at the middle of the sorted
Tap Drill Guide. This gives a thorough overview
of drilling options for a specific thread, and is
much more useful than an ordinary tap drill
chart. There's another worthwhile feature in
the Tap Drill Guide. For those Thread Types that
have Percent Thread data available, clicking the
desired percent value in the Percent Thread
listbox will cause the suggested drill size for
that thread to be positioned at the middle of the
Tap Drill Guide. Tap drill data for form (roll)
taps is available for many of the thread types.
If the Form option button at the top of the Tap
Drill Guide is enabled, selecting it will cause
display of recommended drills for form taps.
55 Thread Selected
58The Thread Info WindowSome Useful Information
59The Thread Report
You can display and (optionally) print this
report by clicking the Preview button. To print
the report immediately from the Threads Window,
click the Print button.
60The Drill Depth Calculator
- The Drill Depth Calculator outputs the depth to
feed a center drill, spot drill, or countersink
to machine a specific chamfer diameter on the
face of a workpiece, as well as the depth to feed
a twist drill to machine a full-diameter hole of
a specific depth.
61Drill Depth Calculator Usage
For Center Drills, you'll need to enter the Drill
Size and Chamfer Diameter. For Spot Drills,
you'll need to enter the Drill Angle, Chamfer
Diameter and Drill Diameter. For Countersinks,
you'll need to enter the Tool Angle, Chamfer
Diameter and Tip Diameter. For Twist Drills,
you'll need to enter the Tool Angle, Drill
Diameter and Full-Diameter Hole Depth. For all
but center drills, there are two ways to specify
the included angle of your tool. The first is a
Std Angle dropdown list of industry-standard
angles for the active tool type. The second is a
User Angle edit box that allows you to input
whatever geometrically-valid angle you like.
62The Surface Finish Calculator
The most important factors affecting the
theoretical surface finish are feedrate and tool
radius. The Surface Finish Calculator displays
the range of feedrate/surface finish combinations
available when using a specific tool radius. The
best way to get started is to make sure you're in
the correct units mode, then select the radius of
your tool from the dropdown list. Next, enter
the finish you need to achieve. The theoretical
required feedrate will be calculated and
displayed. Changing the feedrate updates the
surface finish for the active tool
radius. Changing the surface finish updates the
feedrate for the active tool radius. Changing
the tool radius updates the feedrate for the
active surface finish. The maximum value
allowed for surface finish is 500 microinches or
12.7 micrometers.
If Turning is selected in the Machining
Calculator, you can assign the feedrate
determined by the Surface Finish Calculator to
the Turning operation by clicking on the Post
button.
63The Machining Data Editor
- The Machining Data Editor lets you edit the data
used by the Machining Calculator to calculate
recommended speeds and feeds. - Each tool has edit boxes beside it that contain
either a cutting speed or a feedrate value. - The boxes labeled SFM or SMM show the cutting
speeds for the various tool types when machining
the Active Material. - The labels for the other boxes represent tool
diameters, and the edit boxes contain the
corresponding feedrate values for the tools when
machining the Active Material. - Machinability is used to calculate machine power
requirements for a specific material. In the
Machining Calculator, a material with a larger
Machinability value requires more power than does
a material with a smaller value.
