Development of Processing Machine for Convex Curved Rake Face of Pinion Cutter

摘要

According to the new profiling characteristic of carbide pinion cutter with convex curved rake face,the verifying experiment for principle of processing method is done on the four axis vertical processing center.According to the experiment result,special machining equipment of convex curved rake face of pinion cutter is designed and developed,position of each axis and motion relationship is ascertained,tool path position of CNC machining is solved,path fitting of grinding wheel machining is done,machining experiment of pinion cutter with convex curved rake face is done by using the developed processing machine,The experiment result shows that the designed machining method and developed machine are proper for machining requirements,changed tendency curve of surface roughness is obtained,the range of cutting parameters is ascertained for getting better surface roughness.
