      Machining of Titanium (Ti6Al4V) Alloy Using RSM.

AB  - Titanium and its alloys exhibit numerous uses in aerospace, automobile, 
      biomedical and marine industries because of their enhanced mechanical properties. 
      However, the machinability of titanium alloys can be cumbersome due to their 
      lower density, high hardness, low thermal conductivity, and low elastic modulus. 
      The wire electrical discharge machining (WEDM) process is an effective choice for 
      machining titanium and its alloys due to its unique machining characteristics. 
      The present work proposes multi-objective optimization of WEDM on Ti6Al4V alloy 
      using a fuzzy integrated multi-criteria decision-making (MCDM) approach. The use 
      of MCDM has become an active area of research due to its proven ability to solve 
      complex problems. The novelty of the present work is to use integrated fuzzy 
      analytic hierarchy process (AHP) and fuzzy technique for order preference by 
      similarity to ideal situation (TOPSIS) to optimize the WEDM process. The 
      experiments were systematically conducted adapting the face-centered central 
      composite design approach of response surface methodology. Three independent 
      factors-pulse-on time (T(on)), pulse-off time (T(off)), and current-were chosen, 
      each having three levels to monitor the process response in terms of cutting 
      speed (V(C)), material removal rate (MRR), and surface roughness (SR). To assess 
      the relevance and significance of the models, an analysis of variance was carried 
      out. The optimal process parameters after integrating fuzzy AHP coupled with 
      fuzzy TOPSIS approach found were T(on) = 40 micros, T(off) = 15 micros, and current = 2A.
