Abstract

A conventional machining has the limitation for machining advanced materials since it requires that the cutting tool material is harder than the work piece material. There is the need of use of non-conventional machining process such as electro-discharge machining (EDM) process for machining of shape memory alloy (NiTinol). A very few investigations have been documented to analyse the machining characteristics of EDM process during machining of NiTinol. In this investigation an analysis has been made on the effects of various process parameters such as polarity, peak current, pulse on-time, spark time etc. on MRR and Taper angle during drilling on shape memory alloy such as Nitinol by EDM process based on L18 OA of Taguchi method. The polarity and pulse on-time are significantly most influential process parameters. Maximum MRR and minimum taper angle are found at 12A/20s/6s and 12A/30s/4s respectively.
