If you have selected Cylinder stock, the following settings are available on the Multiple Stocks Machining dialog:
Face Designation in Multiple Stocks Machining — Use these settings to specify whether the machining operations programmed in the current Face window are machined on the same stock as operations in other Face windows, or on different stock. This ensures that the correct stock is used during simulation.
When you select this option, PartMaker creates a Face that is parallel to the tombstone or table face.
Each Face window using an Independent Stock should have a different Work Offset value set in the Setup dialog.
