The characteristics of plastic chips are smaller than that of metal. The thermal capacity of plastic is small, the thermal conductivity is poor (the thermal conductivity is only three thousandths or less of metal), and the coefficient of thermal expansion is large (1.5~ larger than metal) 20 times). Therefore, the heat generated by the friction during the cutting process is mainly transmitted to the cutter.   Tool selection: In general, it is forbidden to straighten the slender shaft directly. In addition, the outer turning angle of the outer turning tool can be greater than 90°.   With carbide tools, the machining quality is extremely poor and even impossible to machine. When programming, the larger back angle, it is recommended to consider the cemented carbide, the temperature rises rapidly, and the blade is very sharp.
