The metal cutting industry utilizes different processes like milling, turning, shaping etc., to remove the material to form the required product. In all the fore mentioned process, material is removed in the form of chips by a single point or an oblique surface of the tool contacting the work piece at a relative force and this is termed as oblique cutting. Figure 1 depicts a typical oblique machining, such a process involves a 3 dimensional force system acting at the point of cutting which makes it complex for analysis and research work
