I had just programmed a part for my mill. Can I go back into my program and use TBM to help machine a unilateral tolerance to the mean and just update the tool path?.
You can go back at any time and run TBM, but it works off of AFR so if you have customized the toolpaths or settings it will reuse the info from the TechDB. With that said, TBM does not adjust to the "mean" of the tolerance today. What it does is apply different strategies based on the category of tolerance. For example, If the tolerance is undersized, use option A, If Nominal, use Option B, and if oversized, use Option C.
For adjusting the cuts, you can change settings in the operations by leaving the material to the mean in x, y, and Z. You can use the Move Feature option to keep a parametric relationship to the part but adjust the feature in x,y, and z
Machine to the mean was part of the original TBM, but all it was doing was automatically adjusting the operation settings above. It did not account for stack up based on dimensioning schemes. To help with stack-up, we add the move feature as maintains a parametric relationship to the model and allows the programmer to account for stack-up. We are working on other settings for the future, but today, we removed the automatic number adjustments due to the confusion of stack-up and position for the "mean."
