Wire electrode diameter effect on cutting speed,inWEDM of varying height Inconel-718
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2018, Vol 5, Issue 7
Abstract
The wire electrical discharge machine is replacing the conventional machines at very fast rate. There is hardly any conductive and newly developed super alloy which cannot be machined by WEDM. Greater accuracy, higher cutting speed, better surface finish are fascinating features of WEDM. However enhancing cutting speed is still a challenge in difficult to cut material. In this paper a super alloy Inconel-718, is used with height variation, to evaluate effect of cutting speed by using different diameter wire electrode to get better cutting speed. Taguchi’s L27, orthogonal array is used to find the effect of pulse on, pulse off, wire feed, wire diameter and work height on cutting speed. It is observed that small wire diameter gives highest cutting speed at the same operating conditions. Small wire diameter ensures better greater accuracy.
