Cutting force modelling of ultra-precision flycutting of groove

Abstract

Cutting force is a key factor of the cutting plans design, cutting conditions setting, tool wear evaluation and even machined surface topography prediction. However, little research has been conducted on the analysis of cutting force in ultra-precision fly cutting (UPFC). This paper presents a theoretical and experimental study on the cutting force modelling in UPFC of groove. In the present study, an analytic cutting force model has been established to predict the cutting force amplitudes both in the feed direction and thrust direction. Experiments were conducted to verify the simulation results. Theoretical and experimental results show that cutting force in UPFC is figured as a force pulse followed by a series of free vibration signals, cutting parameters such as cutting depth, feed rate seriously affect cutting force amplitude.
