Effect of Profile Geometry and Cutting Speed Override Parameter on Profiling Speed During Tapering Using Wire Electric Discharge Machining

Abstract

The oblique/tapered form of precise components has many applications like dies, nozzles, inserts, cutting tools, and other components. Wire electric discharge machining is an erosion technique that helps in precise machining of hard materials. In the present study, basic profiles were machined using a novel slant-type fixture to achieve a slant surface on Hastelloy X. The shapes like triangle, square, and circle are machined at different slant angles, namely 0° and 30°. This paper aims to study the effects of the cutting speed override parameter and profile geometry on profiling speed of machined profiles. The basic shapes of 1, 3, and 5 mm sides were machined. The cutting speed override parameter affected the most on profiling speed in both the angles irrespective of profiles. The profile geometry also affects the profiling speed although the machining parameters were maintained constant. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
