Then the remaining material to be removed is great, and the metal streamlines of the bar preforms will be destroyed during the cutting process. thus the components compositive mechanism performance are affected.

• 由于弧面凸轮廓面曲线的不可展开性,弧面凸轮传统切削工艺,主要利用棒料在数控机床或成形铣床进行切削加工,切削加工余量大,同时切削时也破坏了圆钢的金属纤维流线,影响零件的综合机械性能;
