In this paper, statistical and regression analysis of kerf width using design of experiments is proposed for WEDM operations. Experimentation was planned as per Taguchi's L'32 (21 X 44) mixed orthogonal array. Each experiment has been performed under different cutting conditions of gap voltage, pulse ON time, pulse OFF time, wire feed and dielectric flushing pressure. Stainless steel grade 304L was selected as a work material to conduct the experiments. From experimental results, the kerf width was determined for each machining performance criteria. Analysis of variance (ANOVA) technique was used to find out the variables affecting the kerf width. Assumptions of ANOVA were discussed and carefully examined using analysis of residuals. Variation of the kerf width with machining parameters was mathematically modeled by using the regression analysis method. Finally, the developed model was validated with a new set of experimental data and appeared to be satisfactory.Keywords

Objectives: In this paper, the effect of reinforcement content, load and speed on the wear behaviour of Cu/SiC metal matrix composite are investigated using design of experiment. Methods: A statistical model is proposed to find the significant factor which affects the wear resistance properties of the prepared composite material. Three samples of composites were fabricated using different SiC content by stir casting. The wear behaviour of composites was evaluated for a variety of load and sliding speed at ambient temperature. Findings: It is found with the increase in SiC content the rate of wear of the composite decrease while with increase in load the wear rate increased. Also with increase of sliding speed wear rate is increased. Among the three variable parameters chosen for the study viz. reinforcement content, load and sliding speed, the load is the mainly prominent factor that affects the wear resistance of the composite. Applications/Improvements: This study can be enhanced further by using different reinforcement’s combinations and parameters. Also the wear tests can be performed at elevated temperatures.Keywords
