Due to the weak rigidity of thinwalled carbon fiberreinforced plastics (CFRPs), these materials are prone to chatter during the surface milling process that results in unstable cutting. Due to the laminated and anisotropic characteristics of CFRP, different layers of materials are unevenly removed during the cutting process, which reduces the quality of the processed surface. Moreover ...

Hard plastics. When milling hard plastics, avoid generating sharp internal corners. The radius of curvature should be at least 1mm. Chamfered edges are also helpful in preventing chipping of part edges during milling by providing a smoother transition between the cutting tool and the plastic workpiece. —B. Kennedy.
