Abstract:The calculation error and limitation of traditional design method of indexable cylindrical helical surface forming milling cutter are solved by establishing mathematical model and combining with computer aided design，so as to apply to the design and production of modern highspeed cutter，and to solve the problem that some areas of the machined helical surface may be distorted and cause overcutting in the cutting process in some cases，so as to make the dimension of the machined part reach the set point.To meet the design requirements，batch and parametric design can be realized by using computer aided design to improve the design efficiency.
