Model of micro-cutting and analysis of micro cutting force

The forces acting on the rake and flank face are analyzed in details, through investigating the mechanism of the cutting surface formation according to the characteristics of micro-cutting. The relationship of rounded edge radius and cutting force is presented. The model of micro-cutting is established and the relationship between the cutting forces and the main parameters are obtained. The mechanism of microcutting is exploded theoretically, which is significant in cutting tools material choosing and cutting tools edge improving.
