Following the workshop on constraint-based/parametric modelling in FreeCAD, let’s take a look at CAM (i.e. computer-aided manufacturing) in FreeCAD! We’ll start with some theory on 3-axis CNC milling, covering
- Different types of milling bits
- Chipload
- RPM
- Feedrate
- Depth of cut
- Conventional versus climb cutting
Next, we’ll check out some options in the Path workbench in FreeCAD, focusing on operations to generate different kinds of tool paths like
- Contours
- Pockets
- Holes
In addition, we’ll look at several modifications of these paths, including
- Ramp entries
- Tags
- Dogbones
If time permits, we’ll run a full example project on the CNC router in the Werkstatt.
