A mechanistic model of cutting force in the micro end milling process

The analysis of cutting force in micro end milling plays an important role in characterizing the cutting process, as the tool wear and surface texture depending on the cutting force. In this paper, an analytical mechanistic model of micro end milling is proposed for predicting the cutting force. The tool–workpiece contact at the flank face is considered in this model. The cutting force model which is considering on cutting edge radius of micro tool is simulated and the validity of that is investigated through the newly developed tool dynamometer for micro end milling. The characteristics of cutting force are used for evaluating the tool condition, damaged layer, and surface roughness in micro machining.
