Reduce cutting forces and reduce the cutting heat

Reasonable choice of turning geometric parameters (1) the role of the anterior horn and options: a) The role of the anterior horn: the former makes turning sharp angle increases, reduce the cutting distortion, reduce the chip and rake face friction and  cubic boron nitride  forces and reduce cutting heat. Effect turning the strength properties and heat stress conditions. Affect the quality of the machined surface. 2) the rake angle of choice: the tool strength permit conditions, use a large rake angle.  Diamond blade  to the workpiece material, tool material, processing properties selection. Workpiece material soft, rake angle should be bigger; workpiece material hard, rake angle should be smaller; cars brittle materials, rake angle should be smaller; cars plastic material, rake angle should be bigger.
