In the present day manufacturing scenario, computer numerical control (CNC) technology has evolved out as a cost effective process to perform repetitive, difficult and unsafe machining tasks while fulfilling dynamic requirements of high dimensional accuracy low surface finish. Adoption CNC would help an organization in achieving enhanced productivity, better product quality higher flexibility. ...

In this research work the tool-chip interface temperature is measured experimentally during turning of EN-31 steel alloy with tungsten carbide inserts using a tool-work thermocouple technique. First and secondorder mathematical models are developed in terms of machining parameters by using the response surface methodology on the basis of the experimental results. The results are analyzed statis...

STUDY SELECTION AND ASSESSMENT Articles or dissertations were selected if they were qualitative reports, addressed turning points or a process of change in health behaviour over time, and were grounded in or supported by observational or verbatim qualitative data. 2 reviewers independently coded study findings in categories of main concept, pre-change influences, turning point, and steps in the...

This paper discusses the use of Box Behnken design (BBD) approach to plan the experiments for turning the yield of CVD, thickness and layer number of graphene sheets with an overall objective of optimizing the process to provide higher graphene production volume, fewer layers and thinness structure of graphene. BBD is having the maximum efficiency for an experiment involving four factors such a...

Article history: Received: 19.02.2013. Received in revised form: 29.03.2013. Accepted: 29.03.2013. There could be different procedure variants of chip removal by the applied kinematic relations in turning operations. Recently, some research and analysis of these variants have come to the front since turning can replace grinding in precision machining operations due to the development of tools w...

This paper presents an application of the Taguchi method parameter design to optimize the surface roughness, tool wear and cutting force by hard turning process. The Taguchi parameter design method is an efficient method in which response variable can be optimized, given various controls and using fewer experimental runs. Hard turning is the latest trend in all manufacturing industries and it i...
