Abstract
To improve the quality of cylindrical roller bearing, on of the most important factors is edge quality of the end of a roller. The authors already have presented the edge chamfering method by means of water jet in the previous paper. This paper presents the analytical study on the machining mechanism of the proposed method. The analysis is done based on abrasive distribution model within the jet acquired experimentally. The analysis has capability of predicting the machined geometry, taking relative distance and orientation between the workpiece and waterjet. The analytical results are proved by the experimental results.
