The milling process is always required to achieve dimensional tolerance for the nearnetshape carbon fiber reinforced polymer (CFRP) parts. However, delamination and cracking are inevitably induced in milling CFRP due to the excessive milling forces. The milling forces should be thereby well controlled to reduce damages of CFRP parts.

Extrusion leaves stress in plastic, and so does the cooling process—the outside cools faster than the inside, leaving a lot of residual stress in the surface, Hechtel said. When you machine the plastic, the residual stress can make the workpiece deform as you remove material. ... You mill the shape of the workpiece into the jaws, so you can ...
