Sustainable Operation Planning and Optimization in Manufacturing: A Case with Electro-Discharge Machining

Demands on today’s products have become very complex as buyers expect enhanced quality. Choosing a proper integrated manufacturing technology is the most difficult and time consuming act for enterprises. Again, Planning plays a crucial role in embedding sustainability into the day to day operations and businesses maintain a strong focus on factors that have a clear and direct effect on their economic performance like cost of materials, profit etc. Electro-Discharge Machining (EDM) is a thermoelectric energy based non-traditional machining processes with Material Removal Rate (MRR), Overcut and Surface Roughness as important outputs. People working on EDM have used a number of ways to optimize them. The objectives being more efficient material removal coupled with reduction in overcut and improved surface quality. In this study the same are individually and simultaneously optimized using Taguchi method on EN41 material and the best combination of the input parameters were identified. Results are validated to show its efficacy in using these in different manufacturing shop floors
