INVESTIGATION OF PROCESS PARAMETERS AND MACHINABILITY ON DIE SINKING EDM FOR INCOLOY 800 WITH DIFFERENT PROFILE ELECTRODE

Abstract

In Electric Spark Machining, choice of manufacturing constraints is a necessary feature. This Electrical Spark Machining is an advanced process in all manufacturing processes. For the manufacturing of sophisticated parts, which require accurate machining that time Electric Discharge Machining used. A super alloy, heat-treated tool steel, ceramics, heat resistance steels etc. which are tough to machining. For this, we use Electric Discharge Machining which also known as Electric Spark Machining. Incoloy alloy set in the group of super stainless steels. The main element of this incoloy alloy is nickel-chromium-iron with other extra copper, molybdenum metal. High solidity at high peak temperature and super resist of erosion is the main feature of incoloy alloy. Vast application of incoloy 800 is like Heat exchangers, Carburising equipments, Heating elements and nuclear steam generator tubing. In our research, we use hollow, flat, convex and concave electrode profile for machining of incoloy 800. MRR and TWR are the parameters we analyze after the experiment.
