Cost Optimization of Internal Grinding

Abstract

This paper presents a study on cost optimization of internal grinding. In this study, the influences of grinding process parameters including the wheel life, the total dressing depth, the radial grinding wheel wear per dress and the initial grinding wheel diameter on the exchanged grinding wheel diameter were investigated. Also, the effect of cost components including the machine tool hourly rate and the grinding wheel cost were taken into account. For finding the optimum exchanged grinding wheel diameter, a cost optimization problem was built. Based on the results of the optimization problem, a formula for calculating the optimum exchanged grinding wheel diameter was proposed. With the optimum diameter, a new and effective way of using the grinding wheel was proposed and both the grinding cost and grinding time can be reduced considerably.
