Analysis of chip formation of several kinds of highpolymer has been conducted in order to establish the optimum cutting conditions in view of the background that ever increasing application fields of highpolymers necessitate various types of machining. The mechanical properties of highpolymers vary widely depending upon the types, that is, from rubber-like elasticity to glass-like brittleness, and are also affected by strain rate and temperature. Thus the behavior of chip formation of highpolymers differs from that of metals, namely, the types of chip formation are classified into continuous and discontinuous, moreover the former is subdivided into continuous flow^* and shear, the latter into discontinuous simple shear, complex shear and crack. These types of chip depend not only upon the characteristics of the work material but also upon the magnitude and direction of stress or strain during cutting.
