In a conventional method for machining sculptured surfaces, cutter location data that is generated from a master model or a surface model is input into a numerical controller. Since the data lacks the information of the original model in any case, there is a limitation to obtain a fine finished surface essentially. To overcome the limitation, we have proposed a numerical control with surface driven interpolation. The numerical control generates servo data by interpolating sculptured surfaces directly. However, the prototype system has a problem that some slight scratches are found on a finished surface. To resolve the problem, this paper proposes a distance estimation method using a digitized model and an acceleration compensation that adjusts acceleration within a tolerance. The experimental result compared with a commercial CAM system shows that the proposed numerical control provides a fine finish and reduces the scratches.
