In the machining processes, the tool chipping are known to be the most dangerous when the variation of end of tool edges is largest. Therefore, chipping has been caused by the stress distribution in the moment of cutting. In this study, in order to predict the shapes of tool chipping with the tool shapes and the cutting conditions, the premier chipping shapes of involute cutter iss predicted by the stress distribution value of cutting edges and it is verified by the experiments. The growth behavior of the tool chipping is considered through the experiment of gear cutting and in case of evaluation of specific cutting energy in the proper machining conditions through the simulation result, it can be known that the prediction of cutting force is possible accurately.

In this study, the simulation program is developed where the tooth profile error in internal gear shaping is calculated considering several factors which affect it. This factors are the circular feed of the pinion cutter, the interference by the geometric conditions of the cutter and the internal gear, the deviation from the theoretical involute profile of the cutter and the eccentricity of the cutter and the internal gear. With this program, the effects are investigated which the geometric conditions and the cutting conditions in internal gear shaping have on the tooth profile error of the internal gear. The condition for the minimization of it is derived and then the results of simulation are adequately verified by measurements of internal gears cut by a pinion cutter.
