Abstract:This paper determines the effectiveness of the ultrasonic machining process with Stellite 6 in terms of the material removal rate and surface finish quality of the workpiece produced. Stellite 6 is the most generally useful cobalt alloy, having excellent resistance to many forms of mechanical and chemical degradation over a wide temperature range. Practical aspects are given on the characteristics of Stellite 6 as functions, type of abrasive slurry, their size and concentration, nature of tool material, and power rating of the machine. The optimum combination of various input factors for the ductile chip formation in the machining of Stellite 6 has been determined by applying the Taguchi multi‐objective optimisation technique and F‐test. The analysis of results has been done using the statistica 7.0 software and results obtained are validated by conducting the confirmation experiments. The results show the considerable improvement in multiple S/N ratios as compared to initial cutting conditions.

- International Journal of Machining and Machinabilty of Materials is a refereed international publication in the field of machining and machinability of materials. Machining science and technology is an important subject with application in several industries. Parts manufactured by other processes often require further operations before the product is ready for application. Machining is the broad term used to describe removal of material from a workpiece, and covers chip formation operations - turning, milling, drilling and grinding, for example. Machining processes can be applied to work metallic and non metallic materials such as polymers, wood, ceramics, composites and special materials. Today, in modern manufacturing engineering, there has been strong renewed interest in high efficiency machining.
