Optimization of Grinding Parameters of Surface Grinding Process for AISI 1018 Mild Steel by using Al2O3 Grinding Tool

Recently, grinding is most common finishing process used for finishing different materials like Cast Iron, Steels, stainless steels, copper, crass, aluminium and its alloy, tool steel, high speed tool steel, nickel alloys etc. Generally the process used for giving finishing to the materials. Super finishing operation also carried out with the grinding process. AISI 1018 Cold rolled steel referred as low carbon steel or mild steel has good mechanical as well as physical properties. It has a good weldability, machinability, easy to forged, easy to cold rolled, good strength and provides ductility. It is used in many applications such as often employed in high volume screw machine parts, commonly employed in shafts, spindles, pins, rods, sprockets assemblies and wide variety of component parts, cars, domestic goods, constructional steel also employed in wire, plate , tin cans, mild steel flanges, tube fittings, pipe fittings, pipes, tubes, fasteners, sheets, rods, bars etc. It can be finished up to 0.46 µm with standard grinding operation generally used in industries. By optimizing grinding parameters, it is possible to achieve optimum surface roughness. Aluminium Oxide is often used in grinding of mild steels. Every parameters in grinding process should be considered for achieving minimum surface roughness value i.e. cutting speed, feed rate, depth of cut, coolant flow rate, grain size for both tool and work material(course/fine), physical properties of material, grit size for grinding tool, thermal effect etc. But still dominating parameter in grinding is cutting speed of grinding wheel second one is depth of cut.
