Optimization of simplified grinding wheel geometry
2019-11-14 Feng et al. worked on a torus-shaped grinding wheel to machine the taper-ball end mill cutter with the constant helical angle. In this research, the normal rake angle of the end-mill cutter is precisely grinded using a moving coordinate system . Chen et al. proposed an analytical model to derive the helical groove and cutting-edge profile of the circular-arc ball-end mill cutter developed during the
