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

Abstract

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 ap and feed rate fz so that at a constant nominal Ac cross section the ratios ap/fz were 0.1 and 10. The effect of the change of the cross-section and chip ratio is shown.

Model of geometric deviations in milling with three error sources

“…This model was validated on a high-feed milling operation. Cutting force and temperature were studied as a function of the milling insert type in [25] and of the milling parameters in [26][27] in face milling of steel workpieces. The best machining strategy to improve the accuracy of the 3D shapes is studied in [28].…”
