The current involute spline broach is analyzed, the grinding technology of involute spline broach with side clearance is described, the profile is designed, and profile error is analyzed.
With the tool of circle vector function, the involute helix profile with error is given, and with the media of engagement line, the error compensation mathematical model is established.
The theoretical analysis and experimental results show that the lead error measurement may share same generation system with involuteprofile measurement by this meshing method.
