The theoretical error of elliptical groove in outer race of plunging constant velocity joint ground by finger grinding wheel is about 0.004 mm. In order to decrease the error, a new grinding method with basin grinding wheel is proposed. When we optimize the design parameters, the basin grinding wheel will avoid the problems that the feasibility and grinding accuracy are restricted by the interference of the head in the grinding process by means of finger grinding wheel, and can be used to ensure the machining precision and the sectional shape of the raceway to the greatest extent. Aiming at the grinding process with basin grinding wheel, the paper establishes the mathematical model, optimizes the parameters by using simplex algorithm, studies the processing principle in detail, and analyzes the machining errors. The simulation results indicate that the theoretical error for elliptical groove ground by basin grinding wheel will be reduced to 0.631 μm. 相似文献

Grinding is used to meet the accuracy and surface finish requirements of the cam profile in most applications. In order to eliminate the contour error and enhance the processing precision of cam grinding, a methodology for contour error precompensation in cam grinding based on case-based reasoning and rule-based reasoning was implemented. By comparing the dimensional error variation and the corresponding adjacent error variation before/after intelligent precompensation, a satisfied result was obtained by applying the methodology to actual processing. 相似文献

This work reports on the subsurface plastic deformation depth (PDD) as a result of grinding of γ-TiAl, where the effects of grit size and shape, workpiece speed, and wheel depth of cut were studied. A grinding model based on a stochastic distribution of the chip thickness was used to estimate the expected maximum normal force per grit ( ${F''_{n\:{\rm max}}}$ ), which was correlated to the PDD. It was found that the PDD shows a linear correlation with ${F''_{n\:{\rm max}}}^{0.5}$ . The results suggest that the indentation model is still valid for grinding if ${F''_{n\:{\rm max}}}^{0.5}$ is used as a PDD predictor variable instead of the total grinding force. 相似文献
