Im machining a 3d model in alluminium that is 4mm deep
No matter what I set the Max Cut (z) value in the tooling setup it always tries to do the whole 4mm depth in one pass.
using quickcam 3d ver 1.3.0.10
You need to check that you are using a Roughing Plan (eg raster roughing) as Finishing plans do everything in one go.
Then set the value for Step-Down in the plan parameters to say 1mm
QuickCAM only uses the tooltype and diameter from VR Milling to make it's calculations
