Creating a contour cleanup pass

[WillAdams (William Adams (Carbide 3D))]

In CC Pro 3D Roughing passes have a “Stock to leave” option:

For other toolpaths it will be necessary to offset geometry:

Adding geometry to cut as a pocket with a finishing pass

One technique which is often suggested to avoid slotting is to add geometry around a part which one wishes to cut out and cut as a pocket down to tab depth — here’s one technique for that. In this case, the project is a bevel gauge which will be cut out of 0.0625" (~1.5mm) thick aluminum: [bevelgauge] Due to the narrowness of the angles, an 0.03125" endmill has to be used, so after importing and scaling the file (we will be cutting out one which is 3") we select the perimeter and offset it tw…

for X and Y — along Z it is possible to get this effect by adjusting the Depth per Pass, e.g., if one were cutting to a depth of 0.5" w/ a Depth per Pass of 0.125" then 4 full depth passes would be made, but if one reduced the Depth per Pass to 0.124", then 4 full depth passes would be made, and then a fifth which would remove only 0.004" of material.
