What is Tolerance Stack-Up Analysis?

• Tolerance stack-up analysis determines if
  dimensioning and tolerancing will meet the fit
  and function demands of the design.

4
What is Tolerance Stack-Up Analysis?

• When to use tolerance analysis
• Will parts interfere?
• What is actual max/min clearance?
• What is the max/min distance between shafts?
• Will my holes really line up?
• What is the max/min length of an assembly?

5
What is TolAnalyst?

• Automated Max/Min tolerance stack-up analysis
• Parts or assemblies
• Uses DimXpert scheme
• Create critical dimension to be evaluated
• Displays analysis results
• worst-case max/min
• RSS max/min
• Contributor list by
• Export analysis to Excel

6
Who needs TolAnalyst?

• TolAnalyst is for designers who
• perform manual tolerance stack-up analyses
• design high precision components
• design products to be produced in high volume
• anyone who currently suffers from assembly fit
  problems

7
Benefits of TolAnalyst

• Reduces prototyping for testing assembly fit
• Optimization of tolerancing scheme for assembly
  and manufacturing
• Fast evaluation
• Identifies key tolerance contributors
• Graphically displays result
• Eliminates error-prone hand calculations
• Know what your worst-case design is

TolAnalyst Workflow
Step 1 Determine what needs to be analyzed
The designer wants to see what minimum gap is
maintained

TolAnalyst Workflow
Step 2 Add DimXpert dimensions and tolerances to
the individual parts in 3D

Step 3 Open the assembly and start a tolerance
study

Step 4 Create a TolAnalyst Dimension to for the
dimension to be evaluated

TolXpert vs. the competition

• TolAnalyst solves max/min worst-case with
  respect to how parts are positioned in the
  assembly - Inventor and PTC cannot

Worst-case minimum
Worst-case maximum

• TolAnalyst example
• 7 instances of same part
• TolAnalyst solves true max/min worst-case
  condition
• Min top shrinks, bottom grows
• Max top grows, bottom shrinks
• Inventor and PTC cant do this

16
Things to Remember

• Maximum/minimum tolerance stack-up
• Identifies key contributors
• Graphically displays result
• Reduces prototyping and testing for assembly fit
• Leverages DimXpert
• Eliminates error-prone hand calculations
• Enables fast tolerance optimization
