Fuzzy-Controlled Machining for Slack-of-Belt Grinding

Abstract

The slack-of-belt grinding method is used in the finishing process of high-grade furnishings and parts used for special functions. However, the abrasive belt flexibility causes difficulty in recognizing its characteristics and in automating this finishing process. In this study, for automation of the slack-of-belt type grinding process using fuzzy theory, fundamental research was carried out. A fuzzy rule was derived by investigating the characteristics of the slack-of-belt and by arranging the experimental results. This control system keeps the amount of stock removal at the required values. This system infers the necessary grinding time from the abrasive belt conditions by employing the fuzzy rule. The belt conditions are judged from the tangential grinding force which is detected when the workpiece is pressed against the abrasive belt. As a result of the experiments, it was found that there was a great possibility of applying the fuzzy theory to the automation of the grinding process using an abrasive belt. © 1993, The Japan Society for Precision Engineering.
