Effect of Process Parameters on Surface Roughness of Mild Steel Processed by Surface Grinding Process

Abstract

Surface grinding process is used mainly to grind flat surfaces. There are many conditions in manufacturing,where the work-piece material is either too hard or its shape is difficult to produce with sufficient accuracy by any other cutting methods, one of the best methods for producing such parts is to use abrasives. Grinding is basically a chip removal process in which the cutting tool is an individual abrasive grain. Surface grinding process cannot be efficiently carried out without the correct fluid. In the present study Horizontal spindle and reciprocating table type surface grinding machine fitted with test rig is used and cutting fluid is applied through the convergent nozzle to throw the cutting fluids at the cutting zone. This process can be utilized to create flat shapes at a high production rate and low cost. This paper investigates the effect of process parameters such as grinding wheel speed, work-piece speed and nozzle angle on the surface roughness value of mild steel specimen produced by surface grinding process. In order to evaluate the effect of selected process parameters, one variable approach has been used in the present study. Plots of various output responses have been used to determine the relationship between the output response and the input parameters. The value of surface roughness of grinded mild steel work-piece varies from 0.77 μm to 0.79μm.
