Analysis of Influence on Machining Characteristics of Nimonic 80

The quality of the finished product depends on the contribution of many factors along with the complex process involved to move forward towards the new product development. Many operations like turning, drilling, milling in metal machining deserves the quality as a predominant measurement. The tool and work piece plays a vital role in machining process which depends on machining parameters such as spindle speed, feed rate, depth of cut, approach angle. In the present work the turning operation was carried out on Nickel alloy (Nimonic 80) as a work piece and the carbide insert was used as a tool for performing the machining operations. The cutting parameters were optimized using Taguchi based grey relational analysis. Provided that, the ANOVA analysis to find the predominant factors that affects the quality were also determined. The experimental results were compared with the predicted results and found to be a promising agreement between the factors and responses.
