Numerical Model for Prediction of Cutting Force in Peripheral Milling Process Including Thrust and Tangential Damping

Abstract:

A numerical model for prediction of cutting force components in peripheral milling process, including the cutting process damping, is proposed. The cutting process damping creates two components (thrust and tangential) of a dynamic cutting force. The total force model is obtained through numerical integration of the local forces. The effects of tool parameters (diameter, helix angle, number of teeth) on process damping and cutting force distributions are discussed. It is shown that the average value of the process damping and the amplitude of the cutting force increase with increasing the tool diameter. On the other hand, when the tool helix angle increases the process damping increases and the cutting force decreases. The number of tool teeth’s has not an influence on the variation of the damping process and cutting force but an influence on the number of cycles of the periodic cutting process.
