Abstract |
S6 is a shock resisting steels. The solidify capacity of group S steels can be restrained by varying their composition instead of adjusting the liquefying procedures and grain size. These steels can grab ideal hardness at higher austenitizing temperatures. The tempering resistance of group S steels can be enhanced by addition of silicon, which also forms a microstructure to resist. S6 tool steels are gradually preheated at 750ºC. Temperature is then expanded to 917ºC trailed by holding the steel areas at that temperature for 15 to 35 minutes. Wire Electric Discharge Machine (WEDM) seems a good option for machining the complicated shapes on medium strength steel. This paper, identify the effects of various process parameters of WEDM such as pulse on (Ton) ,pulse off (Toff), peak current (IP), servo voltage (SV) for analysis the material removal rate (MRR) while machining S6 mild steel material. Central Composite Design is used to plan and design of experts. The output response variable being material removal rate will be measured for all the number of experiments conducted. As the lowest value of MRR indicates the poor cutting rate, the optimum parameter level combination would be analyzed which gives desired material removal rate. These optimized values of various parameters would then be used in performing machining operation in order to obtain desirable outputs. |
