Sustainable Environmental Optimization of Abrasive Water Jet Machining Parameters of AZ31D/B₄C Composite Using TOPSIS Technique

MMCs are well known for their superior mechanical properties but are difficult to machine using traditional machining techniques because of hardness and brittleness. Among the non-traditional machining processes, AWJM was favoured as a cutting technique for hard and brittle materials. It is extremely beneficial in industries where finish quality and precision are the major concerns. Magnesium alloys possess an exceptionally high strength-to-weight ratio and find more application in structural use, especially in the automotive industry, as they are lightweight and have high performance. The research study comprises an investigation of the AWJM potentiality to cut B₄C and AZ31D composites produced based on the application of the Stir Casting process. The microstructure of composite material is observed with care so that Boron Carbide is uniformly dispersed in the magnesium matrix. Two crucial factors that affect machining precision and quality are used to evaluate the AWJM process. The settings are tuned using the Topsis technique to maximize composite material machining efficiency.
