Compared with traditional hard cutting technology, the thread whirling has features of multi-DOF coupling motions and incremental forming with multi-tools. In order to analyze the forming process of thread whirling and obtain the scallop height on cutting surface, considering the specialties of thread whirling technology and thread raceway shape, the(More)
When form grinding special-shaped screw rotor, cubic parameter spline algorithm is used for the numerical calculation of screw rotor profile. And the screw rotor numerical calculation software is design and developed based on MATLAB programming and GUI graphical interface technology. Mutual conversion of the female and male rotor profile, profile(More)
