Popis: | In the present study the effect of cutting parameters on MRR are measured and are optimized. Experiments are performed using SA516 Grade 70 Carbon steel work material and are cut by CNC Oxy-Fuel cutting machine .Taguchi L 9 orthogonal array is used for designing the experiment. Cutting Speed, Stand-off-distance and oxygen pressure are the selected input parameters for Oxy-Fuel cutting and MRR is the output response parameter. For the present investigation the input variables values varies from the 450-500 mm/min for cutting speed, 4 - 8 mm for stand-off- distance and 3.5 – 5.5 kg/cm 2 for oxygen pressure. Regression equations are generated from the Minitab 17.The functional relationship & effect on different parameters were studied. ANOVA is applied to know which input parameter has most significant affect on the MRR. It was noticed that as increase in Oxygen pressure increases the MRR .The MRR with kerf the speed and Oxygen Pressure greatly influences the functional aspect and quality. The interactive graphs are presented in the analysis .The optimum combination for MRR is A3B3C3. The error of experimental results with regression equation are checked by comparing the predicted values with experimental values and found the results are in adequate |
