CUTTING FORCES BY TURNING IN DEPENDENCE OF ENTRY ANGLE

Machinability is assessed by a set of criteria or machinability functions, the knowledge of which is necessary in optimising the machining process. New materials of the cutting tools and new concepts of the machine tools provide new possibilities and cause quantitative changes in machinability functions. This work has studied the cutting forces function, as one of the crucial functions of machinability. The research was done by longitudinal turning the steel 16MnCr5, using the tools made of coated carbides, without the usage of coolants. Obtained results confirm that entry angle significantly influence thrust cutting force, Fp, and therefore is one of the key factors when turning workpieces with high ratio l/d.
