This study aims to explain the interaction between results measured in turning operation. For this purpose, Ti 6Al-4V alloy workpiece was machined on CNC lathe. Surface roughness (Ra), vibration and energy consumption values were determined by turning. Experimental analyzed statistically. Response surface method (RSM) grey relational analysis used statistical analysis. In RSM analysis, regressi...

Concrete with gangue which made with ordinary Portland cement at different water binder ratio (0.35, 0.40 and 0.45) or ordinary Portland cement at water binder ratio of 0.35 incorporating 10% fly ash or 20% fly ash; 20% fly ash and 1% early strength agent, slag with the replacement of 15% or 30%, or 15% fly ash and 15% slag were made and exposed to a wetting–drying sulfate environment. The comp...

Solid state joining techniques are increasingly used in different types of materials, this work TP347HFG austenitic stainless steel will be welded with HiPerFer ferritic stainless-steel alloy due to their similarity properties some extent after making heat treatment addition difference cost which save for economic reasons. In work, a three-dimensional finite element model was developed. The the...

Abstract Friction stir welding (FSW) is a solid-state process, which has significant role in processes for nonferrous alloys. Conventional arc aluminum alloys such as metal inert gas (MIG) and tungsten (TIG) are replaced by FSW. The effect of FSW parameters rotational traverse speeds, tool geometry, plunge depth, tilt angle, etc., on weld quality were considered several optimization studies. He...

The theory instrument of grey relational analysis is grey relational grade between the sequences. The grey relational grade is a measure of the degree of association between two factors, or between two systems. It describes the relative changes among the various factors in the development process of the system. In turn, we can calculate the grey relational grade, compare and judge the grey rela...

In present the improved demand of lightweight materials by high strength to weight ratio in the aerospace and automotive industries has managed to the development and custom of Al-alloy-based composites. In this paper an effort has been prepared the Al6082+Cu+Zn composite material and the optimization of CNC milling process parameters for two different work materials of compositions are Al6082 ...

In this study, a multi objective optimization for end milling of Al 6061 alloy has been presented to provide better surface quality and higher Material Removal Rate (MRR). The input parameters considered for the analysis are spindle speed, depth of cut and feed. The experiments were planned as per Taguchis design of experiment, with L27 orthogonal array. The Grey Relational Analysis (GRA) has b...
