They find it easier to process; the surface finishes are nicer; size is easier to hold; dwells are better; its more predictable than steel. To improve the efficiency and precision of grinding, more research needs to be conducted to the grinding process and find the optimal grinding parameters. Thats equivalent to chip clearance on a single-point cutting tool. Indexable tooling using indexable inserts, also known as throw-away cutting edge concept does away with brazing and grinding of cutting edges. In order to determine the angle of turning tool, three coordinate planes should be established: cutting plane, base plane and main section. 3 The main angles of turning tools and their functions are rake angle ( 0), rake angle ( 0), main deflection angle (KR), minor deflection angle (KR) and edge inclination angle ( s). This double face grinding is much more efficient than normal surface .
