Treatment of products made of polymeric materials

The properties of polymeric materials are considered from the point of view of processability. The differences of the chip formation process during the treatment of products made of polymeric materials compared to the treatment of metal products are shown. The types of chips formed in the process of cutting plastics are studied, which, as during the treatment of metals, yield information on the phenomena occurring in the zone of cutting (deformations and temperatures) and the quality of the treated surfaces. The empirical dependences of the forces of cutting on the treated material, the material of the cutting edge of a tool, and its geometrical parameters are given. The problems of the wear of tools during the treatment of polymeric materials and the features typical for the treatment of polymeric materials by cutting are considered.
