Stock on facing

[magicniner]

Your time creating paths would be normal if you follow industry conventions.

Top of Part should be the top of your part, your stock should be defined correctly within the software and your CAM can then see what is required for a facing cut on the top of the part, without you defining the depth of material to be removed, because it knows the depth of stock above the part. You just tell it the depth of cut you want to use with your cutter and the CAM will work out if it needs one or more passes.
