Investigation on MRR and RA of Surface Grinding on EN31

?Surface grinding is most common process used in the manufacturing sector to produce smooth finish on flat surfaces. Metal removal rateand Surface qualityare the two important performance characteristics to be considered in the surface grinding process. The process of grinding is affected by several factors such as wheel speed, depth of cut, table speed, material properties and abrasive wheel grade.The main purpose of this study is to study the effects of abrasive tools on EN31 steel surface by using three parameters (Table speed, Depth of cut & Grinding wheel speed). This study was conducted by using CNC surface grinding machine at IIT, Delhi. Total series of experiments performed was 15 set for grinding wheels of Aluminium Oxide.In this work, empirical models were developed for Material removal Rate and surface roughness by considering depth of cut,table speed, wheel speed as control factors using response surface methodology. In this Response surface methodology as applied to determine the optimum machining parameters leading to maximum metal removal rate and minimum surface roughness in Surface grinding process.
