Force and Temperature in Dry Cutting of Hardened W18Cr4V with PCBN
An experimental study was carried out to investigate the effects of cutting parameters on cutting force and temperature in cutting of hardened W18Cr4V with PCBN cutter. Three components of cutting force were recorded by a strain-gauge dynamometer and the cutting temperature was measured by a nature thermocouple of tool-workpiece. The cutting parameters were arranged by orthogonal method. It is shown that the cutting temperature increased with each of the three cutting parameters and the main effecting factor is feeding speed. The three components of cutting force increased greatly with an increase in feeding speed and cutting depth. But the forces decreased a little as cutting speed increased. The main and axial cutting forces depend mainly on cutting depth whereas the radius force is mainly influenced by feeding speed.
