In-Process Evaluation Method of Complex Change in Wheel Working-Surface Condition with Wet Grinding

Abstract

The in-process evaluation method of the working surface condition of grinding wheel is required to perform a grinding more easily and reasonably. In this paper, the method applicable to wet grinding was proposed for the in-process evaluation of the working surface condition. In addition, to clarify the effectiveness and validity, the complex change of the working surface condition during wet grinding of steel was evaluated with the proposed method. As a result, the following were clarified: By improving the response characteristics of the laser micrometer and by equipping the coolant removal device with compressed air, the working surface conditions can be evaluated during wet grinding. Moreover, it is possible to grasp the condition of working surface, where the complex change occurs, at any time during grinding. In addition, the change in the working surface condition can be evaluated quantitatively by measuring the peak distribution of the working surface at constant grinding intervals.
