Optimization of Silicon Carbide Belt Grinding for Ss304 and En8 Steels

Abstract

Belt grinding is a versatile process suitable for Finishing, Deburring, Stock removal applications. Stainless Steel 304 is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. High Carbon High Chromium steel is having good wear and corrosion resistance Properties and are used in Spindles, Cold Rolls, Slitting cutters, Master Tools. There are several objectives possible for grinding with coated abrasives. Among them are the right application (e.g. finish or stock removal), time saving and efficiency of the abrasive belt. To achieve the above objectives, it is essential to look in more detail to the variables, which affect them. These include the work material properties, the grit and abrasive type of the grinding belt, belt speed, contact wheel serration and grinding pressure. Changing these variables will affect the performances of the belt grinding process. The behavior of output parameters shall be well understood for the applications of coated abrasives in manufacturing of components for original equipments. In this study the factors such as Wheel serration, Grit size of belt, Belt speed and Feeding pressure were taken as input variables each at three levels. The experiments were designed with L9 orthogonal array for each metal. The metal removal, belt wear and Grinding ratio are calculated for these experiments and the optimal machine setting for obtaining higher metal removal and Grinding ratio and lower belt wear is found with S-N ratio graph. To achieve the better Grinding of these metals, the outcomes of our experiments can be utilized.
