Never try to force the plastics part. • Avoid sharp “internal” corners. The radius of curvature should be at least 1 mm. Refer to figure 1. • To avoid chipping the edges during turning, boring or milling, chamfered edges are advantageous, providing a smoother transition between the cutting tool and the plastics work. Refer to figure 2.

Milling (machining) Wikipedia

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

Mar 02, 2020 Basically, milling is nothing but the process of removing metals by passing the work-pieces through a rotating multi-point cutter. The machine is able to hold multiple cutters at one point in time, and it works at a high speed for faster removal of metal. In fact, the metal removal rate for milling machines is faster than the lathe machines.
