Investigation of Cutting Forces during Machining Process by High Speed Turning

This paper presents the obtained mathematical models of cutting forces during machining process by high speed turning as a function of processing parameters v, f, a and re. The machining process by turning is performed on NC lathe using ceramic cutting tool inserts and the workpiece material is C 1630 (DIN C 55). Processing parameters are varied in range between v =300 and 700 m/min , f =0,16-0,32 mm/rev, a=0,5-1,6 mm and re=1,22,0 mm. Cutting forces measurement is done at the Institute of Production Engineering and Automation of the Wroclaw University of Technology, Poland using computerized experimental setup with three component piezoelektric dynamometer type Kistler. Experiments are realized acording first order four factorial experimental plan. Mathematical processing is performed at the Faculty of Mechanical Engineering in Skopje using the program CADEX combined with MATLAB.
