Experimental investigation on influence of process parameters &

magnetic field on machining characteristics of Titanium (Ti-6Al-4v)

in EDM.PRESENTED BYA.Aditya Reddy

ABSTRACT : Electric Discharge Machining (EDM) is one of the most accurate

non -traditional manufacturing process available for creating tiny apertures, complex shapes and geometries with in parts and assemblies.

The objective of EDM is to get high MRR along with achieving reasonably good surface quality of machined component.

It has important machining parameters like discharge current (Ip), pulse on time (TON), pulse off time (TOFF), magnetic field (Mf) and work time (Tw) are considered for investigation.

The effects of machining parameters such as metal removal rate (MRR), Tool wear rate (TWR), surface roughness (SR) are investigated with and without magnetic field for titanium (Ti-6Al-4V).

In this experiment a copper tool is used to machine the work piece.
