Parametric optimization in wedm machining process for ohns steel and its experimental validation

Abstract

The demands for alloy materials with high hardness, durability, and impact tolerance continue to be increased with the growth of the mechanical industry. Specialized industries such as space exploration, rocket, automotive, nuclear, medical, moulding, and plastics industries include the use o complex components manufactured of exotic alloys and high-resistance materials. Despite recent advances in technology, conventional machining techniques are not sufficient to machine these materials from an economic point of view. Furthermore, it is difficult, time-consuming, and often impossible to machine these products to complicated forms with conventional processing. newlineIn the last decade, the machine tool industry has increased its productive capacity exponentially, but the maximum output of the machine tools is still unused. The reason why the tools are not running in optimal working conditions is this constraint. Researchers and practical engineers have long been aware of the issue of achieving optimal ranges of operational parameters. Wire EDM machines are used to cut any hardness of leading metals or those which are tough or impossible to cut using conventional techniques. Due to the ability to cut highly hard materials with relatively high precision and automatic feasibility, WEDM has achieved considerable development to satisfy the machining needs of new-age alloys and hard-to-wear products. newlineHowever, the possibility of wire breakage limits the maximum cutting speed achieved. The development of newer, more unconventional materials with different thermal characteristics or specialized materials like Incoloy 800, AISI D3 tool steel, and OHNS steel also has threatened the WEDM process feasibility in the potential production setting. The consistency of the surface still requires special attention. To define the machining capacity for improving the machining rate and performance, more research is required into the present WEDM Features.
