Abstract
The objective of the project is to investigate the effect of current, pulse on time and pulse off time. For the proposed work Material removal rate (MRR) and Tool wear rate (TWR) were chosen as responses and Current, Pulse on time and pulse off time were chosen as process parameters. Hybrid Aluminium Silicon Carbide (Al 7075 + 3wt. % of SiCp+ 3wt. % of B4C) is used as work material and copper is used as tool material. Design of experiment technique is employed for the experimentation. The mathematical models are prepared by Response Surface Methodology (RSM) technique and Box Behnken Design (BBD) is selected to design the matrix for different combination of process parameters. After completion of the experiments analysis was done using analysis of variance (ANOVA) for 90% confidence level.
