Abstract
High machining accuracy is the unremitting pursuit of grinding technology. The radial deformation of grinding wheel is an important factor affecting the machining accuracy of the workpiece. In this study, a force model of grinding wheel during grinding was established, considering centrifugal force and distribution grinding force. The radial displacement and Mises stress distribution of grinding wheel under different grinding parameters (peripheral velocity, grinding depth, and feed speed) were obtained by finite element simulation based on the established force model. The simulation results showed that the radial deformation of the lowest point of the grinding wheel was most affected by peripheral speed, which increased with the increase of peripheral speed and decreased with the increase of grinding depth and feed speed. The actual grinding depth had deviation caused by the radial deformation of grinding wheel, especially in grinding with large grinding depth and feed speed. The deviation value of grinding depth was also obtained. This work can provide a reference for compensating the deviation and has certain engineering significance for improving the machining accuracy of workpieces.
