Abstract:According to the basic principle of cylindrical helical surface forming，the contact lines and helical end section of workpiece helical surface and formed grinding wheel rotary surface are analyzed in detail.In order to solve the technical problem of complex helical end section of highperformance new twist drill，which is impossible to realize onetime grinding helical groove，a method of optimizing the grinding profile and grinding the spiral groove of twist drill helical end section by section correspondence is proposed.The correctness of the technology is verified by simulation.
