Abstract:

Purpose In the current exploration, the machining of a Nimonic 90 superalloy material was carried out in a die-sinking electric discharge machine. Experimentation was performed to investigate the impact of three input machining factors – current (I), pulse on time (Ton) and pulse off time (Toff) – on various response characteristics such as material removal rate (MRR), surface roughness (Ra) and electrode wear rate (EWR).

Nickel hydroxide electrodes with flower-like structure were prepared by pulse electrodeposition method. The samples were characterized by XRD, SEM and electrochemical measurements. XRD results show a typical characteristics of α-Ni(OH)2. SEM results show the morphology can be controlled by the ratio between on-time (Ton) and off-time (Toff). If Ton is constant to 10s, a flower-like structure will be obtained when Toff is bigger than 20s.

Wire Electric Discharge Machining (WEDM) of Titanium grade alloys with coated electrodes has several advantages over the traditional machining process such as increased productivity, reduction of processing cost, and improved material properties. The main objective is to create a relationship between WEDM parameters such as Pulse-on (TON), Pulse-off (TOFF), and Indicated Power (IP) with surface roughness (Ra) and Material Removal Rate (MRR).
