Abstract

The hybrid machining process is performed by connecting the ultrasonic machine tool with
its +ve & -ne poles that are linked to the tool electrode as well as the work piece, respectively. Due to
the comparative movement between the tool electrode and the work piece a pulse discharge is
generated. In this the two-hybrid process, the EDM & ultrasonic machining are complementary
techniques. Experimentation on Titanium Alloy coated to ceramic results showed that the MRR is a
bit higher than just the combination of USM as well as the EDM. The surface roughness obtained look
similar to that of finishing obtained in the USM.
