Abstract

In this study, a grinding process roughness model was proposed. To produce the proposed roughness model, the dressing and grinding conditions that affect the roughness were used as variables with respect to previous research results; in addition, the grinding wheel wear after grinding was also considered using these variables. The equation to represent the wear of the grinding wheel was developed using the equivalent chip thickness and time delay between the programmed and actual infeed rate. The proposed roughness model was also used to optimize the grinding process. The dressing and grinding costs, which are a function of time, were used as the cost function to optimize the grinding conditions and a differential evolution algorithm was applied to minimize it. Experiments were carried out to verify the performance of the proposed roughness model and optimization algorithm.


Keywords: Grinding, Roughness, Optimal, Differential evolution
