Abstract:

AISI A2 steel is an air hardened cold work steel. It is a 5% Chromium steel that provides high degree of hardness after heat treatment with good dimensional stability. It offers good toughness with medium wear resistance and is comparatively easy to machine. Wire Electric Discharge Machine (WEDM) seems to be a good option for machining the complicated profiles. This paper, identify effects of various process parameters of Wire EDM such as pulse on time (Ton) ,pulse off time (Toff), peak current (Ip) and servo voltage (Sv) for analysis of cutting rate (CR) while machining AISI A2. Central Composite Design is used to plan the design of expert. The output response variable being cutting rate will be measured for all number of experiments conducted. The optimal parameter level combination would be analyzed which gives desired cutting rate. These optimized values of different parameters would then be used in performing the machining operation in order to obtain the desirable outputs.
