Abstract
In developing chamfering equipment for cylindrical parts made of tungsten carbide, fundamental research was performed using the quality engineering method. The conclusions are as follows. (1) Fine grain size has a large effect in reducing grinding force in the direction of the grinding wheel spindle. This large effect on reducing grinding force in radial and tangential directions cannot be maintained even with changes in processing conditions. (2) Low feeding speed condition is a large effect factor in reducing grinding temperature of wheel surface. (3) Long dwell time is a large effect factor for chatter form suppression. The above knowledge was utilized and trial production development of the chamfering equipment was carried out.
