Cutting edge preparation of PCBN inserts

摘要：

　　In order to increase tool life and workpiece surface quality,cutting processes with geometrically defined cutting edges demand inserts with a targeted prepared edge.For example,chamfers are largely used in many processes to provide edge strengthening without damaging the chip flow.In order to achieve a stable and reliable cutting process,small and uniform chamfers are necessary.In this context,the influence of grinding parameters on the edge quality and on the chamfer width deviations is investigated.It was found that larger abrasive grains increase edge chipping and that elastic deformation during chamfer grinding at insert comer radius is the main responsible for chamfer width deviation.
