Thermal Effect on Surface Finish in Grinding Process

Mr. Dlilp M Patel

Abstract :

Within the spectrum of machining process, the uniqueness of grinding is found in its cutting tools. Prehistoric man’s aasive tool was natural sandstone, which contains grains of sand in a silicate bond matrix. Modern grinding wheels are faicated by cementing together aasive grains, usually from man - made materials, with a suitable bonding material. Grinding processes are often selected for final finishing of components because of their ability to satisfy stringent requirements of surface roughness. The reliability of mechanical components, especially for high strength applications, is often critically dependent upon the quality of the surface produced by machining. Surface quality may be considered to consist of two aspects: surface integrity and surface topography. Surface integrity is associated with mechanical and metallurgical alterations to the surface layer induced by machining. Surface roughness produced by grinding depends on various factors such as, type of grinding wheel, spindle speed, collent, alignment of workpiece, feederate, depth of cut etc. among therse factors, we analize variation of surface roughness with varying three parameters 1. Wheel Head Speed 2. Depth of Cut and 3. Feederate. It is found that there are certain values of parameter for getting good surface finishing in grinding process for each material and size of the workpiece. If we decrease or increase these values from its optimum value, it results in bad surface finish. Thus we will perform experiment on two workpiece of different material and get optimum value of these parameter, as how variation in these parameters affect the surface finishing.
