This study investigates optimal parameter setting in abrasive waterjet machining (AWJM) on aluminium alloy AA 6351, using taguchi based Grey Relational Analysis (GRA) is been reported. The water pressure, traverse speed and stand-off-distance were chosen as the process parameters in this study. An L 9 orthogonal matrix array is used for the experimental plan. The performance characteristics whi...

Increasing demand and resource overuse has prompted the exploration of spent secondary materials as a primary raw material for variety applications, leading to more sustainable environment. Spent electric grid ceramic insulator, one waste industry, good hardness strength. It can be reused value-added in Abrasive Water Jet Machining (AWJM) industry. The present work deals with generation cost-ef...

Some brittle materials have found wide applications because of their excellent thermal, chemical, and wear resistance characteristics. Impeding the use of these brittle materials in precision engineering applications is the fact that currently it is very difficult for them to be machined in a way that ensures high precision in form and to a good surface finish. A non-traditional or unconvention...

Nontraditional manufacturing (NTM) involves nontraditional transport phenomena and often nontraditional media. Thermally based energy transfer is the main material removal mechanism for several nontraditional machining processes including electrical discharge machining (EDM) and laser machining (LM). Thermal phenomena are also central in processes such as laser forming and direct metal depositi...

INTRODUCTION The continuing drive towards miniaturisation in a number of industries including semiconductor, optoelectronic and medical is stimulated by requirements which include enhanced functionality, performance and reliability, increased energy efficiency, a cleaner environment, improved healthcare, together with reduced costs etc. [1, 2]. Also, new products for fastgrowing industries like...
