10 Milling Toolpaths for Your First 2D CNC Machining

CNC Milling Toolpaths at a Glance CNC milling toolpaths are typically categorized as 2D 3D 4 axis and 5 axis However the term 2D is a bit misleading since this toolpath uses the Z axis to position a tool for depth For example in the image below we have a prismatic part whose features all reside at various heights on the XY plane.
