Experimental Investigations to Determine Optimal Cutting Parameters in Grinding Operations by Design of Experiments

M. Akruthi, B. Anjaneya Prasad


Grinding is one of the important metal cutting processes used extensively in the finishing operations. Grinding machines are generally used for achieving of high dimensional accuracy surfaces and good surface finish. In most cases, the grinding is the final processing operation. A large amount of coolant is needed to achieve the grinding performance in terms of grinding forces, metal removal rate; temperature developed in grinding zone, Specific energy and better work piece surface finish.

The surface roughness and material removal rates are determined by performing different experiments on grinding of Aluminum alloy 6082 pieces is done in this thesis. This is done by varying the cutting parameters table feed, depth of cut and speed for minimum surface roughness and maximum material removal rates. The parameters considered for experimentation are feed rate 11mm/min, 19mm/min and 28mm/min, the Spindle speed 1100rpm, 1200rpm, 1400rpm, the depth of cut 0.01mm, 0.05mm and 0.1mm. L9 orthogonal array is taken and experimentation is done. The optimization is carried out by using Taguchi Method and regression analysis in Minitab software
