Synopsis:
Synopsis:
Developed and optimized the wire electrical discharge machining (WEDM) process for Titanium Ti 6Al-4V alloy using both Taguchi design of experiments and Particle Swarm Optimization (PSO). Examined the influence of pulse on time, pulse off time, wire feed, and gap voltage on material removal rate (MRR) and surface roughness (Ra). Utilized regression modeling to derive empirical equations and applied PSO to find the parameter set yielding maximum MRR with minimum surface roughness.
Highlighted Skills & Contributions
Process Understanding: Studied the principles of WEDM and core properties of Titanium Ti 6Al-4V alloy.
Experimentation & DOE: Used Taguchi L9 orthogonal arrays to structure experimentation with four process parameters at three levels.
Statistical Modeling: Performed multivariate polynomial regression to model MRR and Ra based on key input parameters.
Optimization Algorithms: Implemented Particle Swarm Optimization (PSO) to maximize machining performance metrics.
Comparative Analysis: Benchmarked PSO results with Taguchi-based optimization and literature values.
Technical Documentation: Compiled detailed process tables, optimization results, and justifications in a comprehensive report.
