Prediction of Cutting Force in Trochoidal Milling Based on Radial Depth of Cut

This paper proposes an approach to predict cutting force of trochoidal milling based on radial depth of cut in order to study the mechanics of trochoidal milling. The tool entry angle and exit angle can be easily achieved to get the cutting force infinitesimals via the radial depth of cut. Through coordinate transformation, a time domain analytical model of cutting force is introduced. Subsequently, a corresponding experiment was done to measure the actual cutting force. Compared with the actual measurement data, the theoretical model is verified to be valid.
