INFLUENCE OF TECHNOLOGICAL PARAMETERS ON THE CUTTING FORCES BY TURNING

Machinability is assessed by a set of criteria or machinability functions, the knowledge of which is necessary in optimising the machining process. New cutting tool materials 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 machinability function. The research was done at longitudinal turning of steel 16MnCr. Coated carbide inserts for roughing and finishing were used, and tool clamping system has enabled the changes of entry angle.Obtained results confirm that entry angle and geometry of cutting insert significantly influence cutting forces especially thrust cutting force
