Optimization of Wire EDM Process Parameters for Medical Grade Nickel Titanium Shape Memory Alloy

Study on Effect of Process Parameters on Responses during Planetary Edm of Titanium Grade 5 Alloy

Planetary or Orbital tool actuation is one of the process improvement techniques used in Electro Discharge Machining (EDM) process which has multi facetted advantages. In present work, an attempt has been made to study the effect of various process parameters during planetary EDM of Ti-6Al-4V; a material which is difficult and expensive to machine by conventional methods. Parameters viz. Pulse ...

Nickel Titanium and Nickel Titanium Hafnium Shape Memory Alloy thin films

Shape Memory Alloys (SMAs) coatings of NiTi and NiTiHf have been deposited onto Si substrates using pulse DC sputtering. Coatings of NiTi with compositions containing 45 to 65 at% Ti have been fabricated by co-sputtering NiTi with Ti. NiTiHf coatings with Hf compositions ranging from 2 to 30 at% Hf have been fabricated by co-sputtering NiTi with Hf. XRD results reveal the as-deposited coatings ...

Modeling and Optimization of Wire EDM Process

The present work is aimed to optimize the parameters of (WEDM) process by considering the effect of input parameters viz. Time On, Time Off, Wire Speed & Wire Feed. Experiments have been conducted with these parameters in three different levels data related to process responses viz. Metal removal rate, surface roughness (Ra) have been measured for each of the experimental run. These data have b...

Experimental Investigation of Wire-EDM Process Parameters on MRR of Ti-6al-4v Alloy

The objective of the present work was to investigate the effect of the wire electrical discharge machining process parameters on material removal rate of titanium alloy using Taguchi approach. A brass wire of 250μm was applied as a tool electrode to cut the specimen. L36 mixed orthogonal array (2 ×3) has been selected for experimentation under different variables like dielectric conductivity, p...
