TECHNICAL DISCUSSION ON THE WIRE EDM PROCESS AND A CASE STUDY

Abstract

Wire electrical discharge machining (EDM) is an innovative technique in the field of machining, widely used for the manufacturing and restoration of parts with high precision and superior surface finish. This paper aims to provide a comprehensive discussion on this process, highlighting its main advantages and applications. A literature review of reliable studies and articles serves as the chosen methodology to ensure the credibility of the information, sourced from reputable institutes and industries in Brazil. Additionally, a case study conducted in an industry in the interior of São Paulo is presented, demonstrating the effectiveness of the technique for keyway channel opening. The case study includes tests on gears and hollow shafts. Specific factors such as cutting time, precision, dimensional accuracy, and surface finish are considered to establish wire EDM as an efficient alternative for certain industrial applications, particularly in the production of complex, low-demand parts. The study also aims to leave room for new tests that can refine the operation's parameters, making it an even more competitive technology compared to traditional machining techniques.
