Effect Of Aluminium Powder Mixed EDM On Machining Characteristics Of Die Steel (AISI D3)

Powder mixed electric discharge machining (PMEDM) is a recent innovation of EDM for enhancing its capabilities. The objective of present research work is to study the influence of process parameters such as peak current (Ip), pulse on time (Ton) and Aluminium powder concentration on machining characteristics of AISI D3 die steel with round copper electrode. The machining characteristics are evaluated in terms of material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR). It is found that aluminium powder mixed in dielectric fluid significantly affect the machining performance
