Abstract:

In order to improve the accuracy of powder metallurgy gears,a numerical simulation method to calculate the profiles of grinding wheels for CNC (Computerized Numerical Control)was put forward,and the software for the profile calculation and machining of the grinding wheels was developed.A tooth-grinding experiment was then perform ed.Th e experimental results indicate that the proposed method is of simplicity an d rational data construction,which call be used to calculate any kind of gear shape.Th e developed software can be used to calculate the profiles of grinding wheels with any shape,such as spur gears and helical gears,to an alyze the grinding error to op-timize the grinding parameters,an d to create the wheel-dressing program and the gear-grinding program . The resuits of grinding experiment also show that the proposed software is feasible an d precise enough to meet the require-ments in the form grinding of gear dies.
