Optimization of Abrasive Water Jet Cutting Parameters for Advanced Materials

Abstract

Advanced materials such as alloys, and composite materials etc. are replacing other materials in many different manufacturing applications. This is due to the improvements achieved in their engineering properties. Among various advanced materials come the Armox 500T, Titanium alloy Ti-6Al-4V, and CFRP laminates. These materials are exploited in many military and industrial applications especially in the Egyptian industry. The demand on these advanced materials acquire non-traditional machining techniques for better cutting performance.Because of they are often offering high strength and hardness. Productivity in terms of material removal rate beside the cutting surface quality particularly surface roughness and kerf tapering are the most commonly issues encountered with production engineers during machining these materials. Abrasive waterjet (AWJ) is one of the advanced machining processes applied widely in industry. It is superior to many other cutting techniques in processing various materials, particularly in processing difficult-to-cut materials. AWJ has many advantages like no heat affected zone. And has the ability to cut very complicated shapes and profiles. Besides the produced cutting surface has a good acceptable surface roughness value. In other words, there is no need for a secondary machining process. This technology is being progressively used in various industries. However, its cutting capability in terms of the material removal rate and kerf tapering are the major obstructions limiting its further applications. Artificial intelligence (AI) has been established as the area of computer science dedicated to producesoftware capable of sophisticated, intelligent, computations similar to those that the human brain routinely performs. AI techniques have gained popularity in engineering applications in recent years
