Abstract

Machining techniques in the industry generally, modern processing techniques, that come between wire discharging machine, especially mold, defense, aircraft and aerospace industry, is often used. Processing, which is difficult with conventional manufacturing methods, the complex surface forms, the different material types, hard and is capable of handling high dimensional accuracy and surface roughness [1]. This manufacturing technique were carried on Uddeholm Sleipner cold-work tool steel, variable parameters with On time duration, feed rate, and the current value, as fixed parameters off time duration, voltage, pressure of fluid circulation, velocity of wire, wire tension and wire diameter. Surface roughness of the surface was shown changes as a result of the experimental parameters, diameter and circularity deviation values were studied

Keywords

Surface roughness, wire electro discharging machining operation, Sleipner cold work tool steel
