Intermittent turning (IT) is characterized by a different context than continuous (CT). The cutting tool shocked each time it goes off-load and engages new surface. This interruption causes severe conditions, which fatally affect the performance parameters. purpose of this study to assess effects four factors, nose radius (r), speed (Vc), feed rate (f), depth cut (ap), on following output param...

-AISI D3 tool steel is a high-carbon, highchromium, oil-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Typical applications for D3 tool steel include Blanking, stamping, and col...

Laser cutting is a complex multi-input multi-output machining process. To satisfy different requirements regarding laser cut quality it is necessary to determine optimal laser cutting conditions. This paper demonstrates the application of the grey relational analysis for optimization of different laser cut quality characteristics such as the depth of separation line, drag line separation and bu...

The article presents the milled surface quality of Uni-Directional Carbon Fibre Reinforced Polymer (UD-CFRP) composites from Taguchi’s and grey relational analysis. novelty is demonstrating possibility detecting defects in polymer during milling using SEM material used for this study UD-CFRP composite laminates made by hand-layup process. All operations were carried out a solid tungsten carbide...

In view of the characteristics of multi-objective and uncertainty and complexity of the water resources allocation, the optimization of water resources allocation schemes can be regarded as a multi-objective grey relational decision-making procedure. This paper, integrating the grey relational decision-making method and the evidence theory, researches on the optimization method of allocation sc...

An improved Grey Relational Analysis (GRA) is used to quantitatively investigate the impact of Jiangxi Province regional economy on local logistics demand. The grey characteristics of data from regional economy and logistics is studied, which shows GRA is applicable; then a multi-sequence GRA is proposed, which generates total 4 groups of grey relational sequence from three indices of industria...

The aim of this research is to investigate the optimization of cutting parameters (cutting speed, feed rate and depth of cut) for surface roughness and metal removal rate in turning of AISI 8620 steel using coated carbide insert. Experiments have been carried out based on Taguchi L9 standard orthogonal array design with three process parameters namely cutting speed, feed rate and depth of cut f...
