To Determine the Effect of Machining Parameters on Material Removal Rate of Aluminium 6063 using Turning on Lathe Machine

Author : Sunil Kumar and Deepak Gupta

Turning is a basic operation for various industries & it is very essential to optimize the various parameters affecting turning for the optimum condition. Turning operation is affected by both machining parameters & Cutting fluids. The parameter influence most are cutting speed, depth of cut , feed, geometry of cutting tool like principle cutting edge angle ,rake angle, nose radius etc. In order to control MRR it is very necessary to control these parameters. More Material Removal rate directly controls the cost of production and reduces the production. Thus generates the overall increase in profit to the industry. Thus the optimization of material removal rate is very essential for the different machining parameters. . The rotation speed, feed rate and the depth of cut are considered as parameters of interest which directly affects the material removal rate of the used material. The parameter influence most are cutting speed, depth of cut , feed, geometry of cutting tool like principle cutting edge angle ,rake angle, nose radius etc. . In the process of turning operation the different values of cutting parameters, cutting speed (165, 220,275,330), feed rate (.2, 0.3, 0.4, 0.5 mm/rev), depth of cut (.5, 1, 1.5, 2 mm) are selected. It is concluded that the material removal rate is highly influenced by depth of cut than feed rate than speed. Material Removal rate increases with increase of Speed. Material Removal Rate increases with increase of Feed rate. Material Removal Rate increases with increase of Depth of Cut.
