Aiming at the problems of poor heat resistance, deformation, and swelling, a turning test of polycarbonate was carried out under dry cutting, water cooling, ultra-low temperature cooling, and the shape of the surface was analyzed. The morphological differences of machined surfaces were explained from the perspective of relaxation time of molecular chains, crazing generation, and brittle-toughness transition. It is found that, on polycarbonate surfaces, dry cutting produces a large number f strong crazing, water-cooled cutting produced a large number of fine crazing, while the ultra-low temperature cooling cutting produces less crazing. Therefore, ultra-low temperature cooling has a positive effect on improving the processing quality of polycarbonates. [ABSTRACT FROM AUTHOR] |
