Tol stack Analyst is a tolerance analysis tool used to study the effects tolerances and assembly methods have on dimensional stack-up between two features of an assembly. The result of each study is a minimum and maximum tolerance stack, a minimum and maximum root sum squared (RSS) tol stack, and a list of contributing features and tolerances.

Manually entering dimensions and tolerances and doing computations by hand are no longer necessary with TolAnalyst.

Tol stack Analyst performs a tolerance analysis called a study, which you create using a four-step procedure:

Measurement: Establish the measurement, which is a linear distance between two DimXpert features.

Step 1: To build dimensions and choose reference faces, create an auto-dimension scheme. 

Step 2: Click “OK” to finish the process.

Assembly Sequence. Select the ordered set of parts to establish a tolerance chain between the two measurement features. The selected parts form the “simplified assembly”.

Step 3: click Tol analyst tool from Dimxpert manager.

Assembly Constraints. Define how each part is placed or constrained into the simplified assembly

Step4: Select measure faces from position to end face.

Step5: Click next button and select measure parts from assembly.

Step 6: Click “OK.” Choose your measure spot using the construction filter that is shown on the graphic area.

Analysis Results. Evaluate and review the minimum and maximum worst case tolerance stacks.

Step7: Select sample hole and click next approx tolerance value is visible.

Step8: If you want to share report as excel click export result.

Conclusion:

Drastically cuts down on the amount of prototyping usually needed to check assembly fit and function, and it even uncovers “worst-case” problems that physical prototyping would not ordinarily show.

Verifying tolerance systems lowers manufacturing costs by permitting looser tolerances and less costly manufacturing methods when strict tolerances are not required.
