Research on Calculation and Smoothing of Grinding Wheel Profile for Machining Screw Rotor
Upon studying the form grinding principle of helical groove and the conjugate movement between the grinding wheel and screw rotor, the equation of their contact line is firstly derived. The problem of smoothing the profile of grinding wheel is then solved by using the point selection smoothing method which is concludes from the theory of complex curves and numerical analysis. Finally, with the help of computer, the simulation processing is done with the final result shows that this design method is reliable. It can not only reduce the time for design and the number of trial samples but also provides a 3D model which can be used in virtual test of screw rotor.
