In view of the key technical problem of inner gear form grinding
the grinding wheel dressing method for the inner gear form grinding is studied.On the basis of establishing the mathematical model of inner gear form grinding
the coordinate calculating equations for wheel dressing and profile is deduced.Wheel dressing software is compiled based on VC++6.0
which can be used to output the CNC program for dressing form grinding wheel.The practical software running results show that the dressing method is correct and the dressing software is feasible.
