Abstract
In this study, the ultra-precise cutting was carried out using the single crystal diamond tool for 7 kinds of plastics of Polycarbonate, Polystyrene, Polymethyl methacrylate, High density Polyethylene, Polyamide 6,Polyvinyl chloride and Polypropylene. Measurement of the surface roughness and observation of the cutting plane were performed, and the physical property which influenced surface roughness was investigated, and the cutting mechanism in the plastic was clarified.
