In this paper, the influence of micro-EDM-drilling process variables on surface roughness using an integrated multi-process micro machining machine (IMMM) is presented. The machining parameters considered are feed rate, capacitance & voltage and response parameter is surface roughness. Experiments are designed as per full factorial design using Design of experiments. Response surface methodology approach is used for modeling the surface roughness and finding out the optimal values of drilling parameters. The influence of each drilling parameter in micro-EDM process is characterized and the optimum value of parameters is determined. The interaction effects of parameters on surface roughness are discussed and the mathematical model and optimized parameters are validated for micro-EDM-drilling process.

Abstract


In this paper, the influence of micro-EDM-drilling process variables on surface roughness using an integrated multi-process micro machining machine (IMMM) is presented. The machining parameters considered are feed rate, capacitance & voltage and response parameter is surface roughness. Experiments are designed as per full factorial design using Design of experiments. Response surface methodology approach is used for modeling the surface roughness and finding out the optimal values of drilling parameters. The influence of each drilling parameter in micro-EDM process is characterized and the optimum value of parameters is determined. The interaction effects of parameters on surface roughness are discussed and the mathematical model and optimized parameters are validated for micro-EDM-drilling process.
