“Application of Statistical and Metaheuristic Techniques with SEM in Abrasive Waterjet Machining of Composite Materials: A Review”

Abstract

In the era of algorithm-based technologies, researcher explores the scope of optimization of complex real world problems. Abrasive water jet (AWJ) is one of the advance machining processes to cut engineering materials; metals, alloys, and composites, even AWJ machining process can cut hard to machine materials satisfactorily. Recent trends shows augmentation in developments of various types of composite materials. Feature of high strength to weight ratio in composite materials makes it more significant in diversified industries mainly involves defense, aerospace, automobile and sport equipment making industries. Literature provides extensive application of AWJ for cutting, milling, drilling, slotting and turning of composite materials. Real world problems with two or more conflicting objectives requires endeavor to achieve best solutions from the search space of the problem.    The paper consolidates study of both statistical and metaheuristic techniques and its applications in complex machining mechanism of composite materials by AWJ in lucid manner. The intrinsic problem in machining of composite materials are structural inaccuracy, delamination, kerf taper and fiber pull out. The paper covers the systematic study of these issues using scanning electron microscopy (SEM).
