Study on Improvement of Machining Accuracy in Creep Feed Grinding with Difficult-to-grind Material : 1st Report, Estimation of Profiled Wheel Wear

摘要

The porous type wheel made for creep feed grinding with difficult-to-grind materials is excellent for the prevention of workpiece burning, but its wear is usually considerable. So we must exactly obtain the characteristics of wheel wear in the case of precision profile creep feed grinding operation. In this study, V profiled wheel wear is examined experimentally with SUS304 and SKD11(Hrc60) materials. From the results, characteristics of the edge wear and the linear relationship between wear and the inclined angle of the wheel surface are obtained. Further, a method is proposed by which any profiled wheel wear is able to be estimated using this relationship from a simple creep feed grinding test. And the usefulness of the method is examined experimentally.
