ST-Machine Explorer and DLL

Adding Part Tolerances

The ST-Machine Explorer will read dimensions, tolerances, and surface properties if they are present in the AP203e2 or AP214 CAD geometry for the workpiece. You can also create them yourself and associate them directly with the part geometry.

Because everything is linked to the part, ST-Machine can display the tools and operations that affect each tolerance, enabling tolerance-driven tool compensation

Now you have a complete, visual, description of your machining process that can be checked for collisions visually by the operator or by using CNC verification tools.

Next, view and simulate the toolpaths, workpiece, and tolerances!
