Optimization of Machining Parameters in Turning Operation of Bronze Metal for MRR & Hardness

Author : Sandeep Sharma and Deepak Gupta

In most of the production industries mostly the number of components is manufactured by the Metal removal turning. Centre lathe is a general purpose machine which is mostly used in most of industries and large amount of work is carried on it. First pilot experiments were done on the work piece using random values and then from those pilot experiments the suitable values of these parameters were selected. On the basis of observations from the pilot experiments three values of Cutting speed 220,330,440, three values of feed 1, 1.5, 2 and three values of Depth of cut 1, 2, 3 were chosen. L9 orthogonal array performed using these values. It is concluded that for MRR be maximum factor Cutting speed has to be at high level 3, Feed has to be at high level 2 & D.O.C has to be at high level 3. It is concluded that for hardness to be maximum Cutting speed has to be at level 2, Feed has to be at high level 3 & D.O.C has to be at level 2.
