Title: Manufacturing Technical Objects
1Manufacturing Technical Objects
2The Manufacturing Process
Step 1 Step 2 Step 3
Design Production Marketing
3Step 1 Design
- Identify a need
- Analyze the technical problem
- Write your specifications
- What is the maximum size, mass etc
- Prepare a design plan
- Prepare a Technical drawing
- Manufacture a prototype
- Test the prototype Does it meet specifications?
- If not return to step 4 prepare a design plan
- Apply for a patent
4Design Plan
- PURPOSE To provide information on one or more
of the operating principals of the object How
does the object work? - Contains the following
- Name of the parts
- Movement of the parts ( see symbols on pg 75)
- Operation forces involved (see symbols on pg 75)
- Any other useful info needed to understand how
the object works - DRAW example from pg 78 of lab book
5Technical Diagrams
- Purpose To provide info on the selected
manufacturing process of the object. How do you
make the object? - Includes
- Important shapes and dimensions to be considered
( rules on pg 73 in lab book) - Names of parts
- Materials to be used
- Linking components ( pg 75)
- Guiding controls ( pg 75)
6Rules for all types of drawings
- Always use appropriate symbols
- Follow rules and conventions for dimensioning
- Make your drawings the proper size ( choose the
right scale pg 68) - Include at the bottom your name, the date, the
title of the drawing and the scale ( refer to pg
74) - BE neat!
7Links
- Linking is the function performed by any
component that connects different parts of an
object - All links can be described with four
characteristics - Direct vs. indirect
- Rigid vs. flexible
- Removable vs. non-removable
- Complete vs. partial
8Characteristic 1
Direct Indirect
The 2 parts are held together without a linking component ( no screws, nails glue etc) EX. CAP OF A PEN The parts require a linking component to hold them together HANGING A PICTURE ON A WALL
9Characteristic 2
Rigid Flexible
The link is rigid when the linking component and/or the surfaces of the linked parts are rigid EX. TOPS OF DESKS TO LEGS The linking component and/or the surfaces of the linked parts can be deformed EX. BIKE TIRE TO RIM ( FEW)
10Characteristic 3
Removable Non-removable
Linked parts can be separated without damage EX. DOOR TO FRAME, PEN CAP Linked parts cannot be separated without damage EX. PULLING WHITE BOARD OFF WALL BROKEN STOOL
11Characteristic 4
Complete Partial
The linked parts can NOT move independently of one another EX. THE DESK At least 1 part can move independently of the others EX. GREEN LAB STOOLS, DOOR, LIGHTSWITCH
12Guiding
- Guiding is the function performed by any
component that controls the motion of 1 or more
moving parts ( see - Guiding can be
- translational ensures straight-line motion of
a moving part ( DRAWER) - rotational ensures rotational motion of a moving
part ( DOOR- HINGE) - Helical ensures translational motion of a part
while it rotates about the same axis ( FAUCET)
13Example A Stapler
14Drawing Views
- You need to include dimensions and lines
indicating what the stated dimensions refer to - Ex
- You need to label your view
- You need to make sure you dont move the item as
you are drawing it too much so that you do not
change your perspective
