Abstract:The main objective of this study is to analyze the effect of cutting speed, feed, and depth of cut on response variables such as surface roughness, tool wear, and material removal rate (MRR). Turning of NIMONIC 80A was carried out at three levels of cutting speed, feed, and depth of cut. Analysis of variance (ANOVA) is used to find which factor is significant for the output parameters. From experimental analysis it is observed that mainly major factor responsible for flank wear is cutting speed,for surface roughness is feed and to get maximum material removal rate is depth of cut. It is found from experimental results that the ceramic inserts gives better surface finish compared to carbide inserts.

Aspect Orientation removed the code scattering and tangling drawback of Object Orientation by encapsulating the cross cutting concerns into their own modules called Aspects. It is gaining popularity these days as lot of languages, frameworks, programming and modeling tools already support aspects and developers have started to embrace these. But there exists lot of legacy object oriented code that needs to be moved to aspects as this makes cross cutting concerns easy to change (localized changes would be enough), test, extend, more comprehensible, etc. Converting it manually is tedious and there exist different techniques that semi automate the process making the maintenance engineer"s job easier. Another approach to the automation process using program slicing is also possible. In this paper, we discuss aspect mining and extraction from program slicing point of view.
