Force and Temperature Conditions of Face Milling with Varying Chip Quotient as a Function of Angle of Rotation

Increasing the efficiency of cutting operations while fulfilling the required (expected) quality of the parts constantly requires a thorough knowledge of the chip removal process. This is especially justified in the case of deviations from the usual (traditional) technological conditions or cutting data, both in terms of cutting theory and technique. This paper summarizes some of the results of a study of cutting force and cutting temperature in face milling. The technological analysis of face milling was performed by FEM simulation, which was compared and validated by measuring the cutting force. The chip removal of C45 rolled steel as a function of tool rotation was studied with two different depths of cut a(p) and feed rate f(z) so that at a constant nominal A(c) cross section the ratios a(p)/f(z) were 0.1 and 10. The effect of the change of the cross-section and chip ratio is shown.
