This paper studies the influence of factors contributing to electrode wear during the micro-electro discharge machining (EDM) process. The paper proposes a method for calculating the volumetric wear ratio based only on geometrical information obtained from the process. The objective of the work is to investigate the suitability of micro-EDM electrode wear compensation methods. Electrode shape deformation and random variations in the volumetric wear are studied as two main factors affecting the applicability of wear compensation methods as well as indicating the accuracy achievable with micro-EDM. EDM drilling and EDM milling are regarded as separate processes as they require different approaches in investigating and implementing the results of the study.

Abstract The Micro EDM is the most suitable machining process in the miniaturization of products at present era. The attainment of close precision is the primary obligation in miniaturization or micromachining. Especially in machining of hard-to-cut materials like titanium alloy. Such alloys are applied in several cutting-edge high-quit applications due to extraordinary properties. Current work presents an exploratory analysis of novel Maglev EDM while machining of commercially used pure titanium alloy (CP-TI). The work outlook is to establish the viability of novel Maglev EDM by comparing the with similar range of micro EDM. The pure DC power is employed with the conjunction of Maglev lucidity to refine the shortcomings of the conventional micro EDM. The novel technology deals with prime concerns of conventional micro EDM and cracked deficiencies like delay response of mechanical actuator and a servo mechanism. The Novel technology uses the logical arrangement of permanent and electromagnet to dealt with inadequacies like short-circuiting and arcing. The results of state of art novel technology proclaimed the improved Material removal rate (MRR), which are lying in the average range of 76.6 µgm/min, whereas the specific energy and surface roughness are observed 33.4 Joule/ microgram and 4.3 µm respectively.
