Size generation process in Internal Grinding with High-aspect-ratio Grinding wheel

Abstract

In the internal grinding with grinding wheel that has high-aspect-ratio to finish deep hole, the dimensional accuracy becomes worse because of elastic deformation of wheel spindle and thermal expansion of not only workpiece but grinding wheel by grinding heat. In this study, grinding force and temperature distribution in workpiece were measured by the developed in-process measurement system. The causes of dimensional error in ground workpiece were experimentally investigated by analyzing wheel wear, elastic deformation, thermal expansion, and the above-mentioned in-process measuring data.
