ABSTRACT
The correct selection of manufacturing conditions is one of the most important aspects to take into consideration in the majority of manufacturing processes and, particularly, in processes related to Electrical Discharge Machining (EDM). It is a capable of machining geometrically complex or hard material components, that are precise and difficult-to-machine such as heat treated tool steels, composites, super alloys, ceramics, carbides, heat resistant steels etc. being widely used in die and mold making industries, aerospace, aeronautics and nuclear industries. The objective of this Project Report is to study the influence of operating parameters of pure copper electrode on the machining characteristics such as, material removal rate for work piece material EN-31 and HCHCr ( hardness 20-22 and 55-56) Keywords: EDM; TON; Ʈ ; MRR; IP;EN-31;HCHCr Purpose: In this investigation, the effects of various process parameters of sinker EDM like: • pulse on time (TON), • • peak current (IP), Duty Cycle(Ʈ)
have been investigated to reveal their impact on material removal rate of materials: • EN 31 (Hardness: 20-22)
• HCHCR (Hardness:20-22) & • HCHCR (Hardness:55-56)
using one variable at a time approach. The optimal set of process parameters has also been predicted to maximize the material removal rate. . Design/methodology/approach: The experimental studies were performed on ELECTRONICA SPRINTCUT EDM machine. Findings: The material removal rate (MRR) directly increases with increase in pulse on time (TON) upto a certain level after that it shows a declining trend and increases directly
