Single Part Tolerance Analysis of Manufacturing Processes

What about Single Part Analysis?

Why do Single Part Analysis?

If a single part is fabricated by going through multiple steps:

  • How do you know if the final part tolerances can be met?
  • If they can not be met, what stage of the fabrication process is causing the issue?

What can you get from Single Part Analysis?

  • Prove or disprove that our process is capable.  

      (Can you meet final part GD&T?)

  • Do you have enough stock (Material) to produce your part?
  • Indicators of which process or stage is causing dimensional issues
  • Ability to test alternative processes in simulation prior to production
Example Single Part Analysis

Think about a 3DCS Variation Analyst model. It contains some math data, with GD&T for important part features, some moves (instructions to put the parts together), and some measures to get the functional and quality output we need to predict how our assembly will work in the actual manufacturing process.

…but what about the other way?? Suppose we need to model a machining process.

Our process begins with a blank part

… it gets placed in a fixture or tool, and some new features get created – holes, slots, machined surfaces, etc.

The in-process part ends up on another fixture, more features get created, and we move the part to the next step in the process. This series of process may even remove ALL of the surfaces from that original, blank part.

How does 3DCS VA analyze this sort of process?

3DCS Variation Analyst can be used to model your multi-step manufacturing process!

Moves are used to specify how the part is located in your tooling during processing or measurement.

Tolerances or GD&T applied to surfaces and features will reflect the capability of your manufacturing process.

Apply measures to evaluate your completed part. Does it meet the requirements on your drawing? Do you have enough material for cleanup?   Use the Monte Carlo analysis results to determine which steps are affecting which outputs.

At the end of your modeling effort, you have a simulation tool you can use to improve your process, or find ways to reduce your manufacturing costs.
