A study of manufacturing models for ball-end type rotating cutters with constant pitch helical grooves

Most of the published work on developing design and manufacturing models of rotating cutters lacks generality and integrity. In this paper, a systemat ic method that integrates design, manufacture, simulation, and remedy, has been developed for a ball-end type rotating cutter. The principles of diffe rential geometry and kinematics facilitate the development of correlative m odels of the cutting-edge and helical groove. Based on the envelope conditi on, approaches for solving the direct and inverse problems related to the m anufacturing models are also presented. The influences of relative feed spe eds of the grinding wheel in machining the groove are discussed, and follow ing this the proposed feed speeds are designed. The effects of design and v irtual manufacture of the cutter are analysed according to the computer sim ulation results of the groove surfaces enveloped by the grinding wheel. In addition, the post-process methods are introduced to finish the residual ma terial and the land of the cutter.
