Machining behaviour of three high-performance engineering plastics

摘要: Polymeric materials have been widely used to replace traditional metallic due their high specific elastic properties. Even though polymeric can be produced as near net shapes, machining is still required make the assembling of final products. The selection tool and cutting conditions very important machine plastics because ductility low melting point materials. In this study, behaviour high-performance engineering polymers, such ultra-high-molecular-weight polyethylene, polyoxymethylene polytetrafluoroethylene, has investigated using a full-factorial design (design experiment). effect factors feed speed, spindle speed drill angle was identified for each response variables (circularity error, surface roughness (Ra) thrust force (Ff)). drilling mechanism substantially affected by physical mechanical properties polymers. Different set-up conditio...
