| Research Abstract |
A simulation model introducing the pitch errors and backlash of rotational axes was developed for five-axis machining center. The simulation that assumes a fine cutting of the cone-frustum was conducted by using the model. As a result, it was confirmed that the simulation results are in agreement with the results measured by means of the ball bar instrument. When the simulation model was applied to the simulation of the truncated square pyramid, the surface profile curve measured by CMM was also in agreement with the simulation results. Therefore, if we use this simulation model, it is possible to predict the machining accuracy and to diagnose the errors.
