The internal gear grinding machine, ZI20A is the first of its kind that is applicable for mass production of internal gears. It is suitable for grinding planetary gears, heat-treated internal or external gears at high speeds with high accuracy. One of the features of this machine is its ability to grind stepped workpieces. In case of stepped workpieces, it is difficult to determine the axial stroke required to achieve proper grinding of the entire tooth surface without causing any interference of the stepped region with the machine parts or grinding wheel. During the grinding test of such workpieces, sometimes the tooth flank remains unground at the ends due to inadequate axial stroke. A new simulation tool has been developed to visualize and analyse the internal gear grinding process. Using this simulation tool, the axial stroke required for grinding can be estimated without performing actual grinding tests.
