This study used finite element analysis software DEFORM-3D to analyze the preform formability and die stress in pre-forming process of forging automobile transmission components. The materials are AISI- 5120 alloy steel JIS-SKD61 mould steel, respectively. research investigated phenomenon folding defects at end final process. First, as shape under pre-formed channel was designed change, its clo...

In the current study, combining powder with dielectric fluid in electrical discharge machining (PMEDM) is a very fascinating technological approach. This approach most effective at increasing both productivity and quality of machined surface same time. The Taguchi–GRA was used to optimize roughness (SR), material removal rate (MRR), micro-hardness (HV) die steels mixed powder. Workpiece materia...

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...

Production of lightweight metals with a higher strength to weight ratio is always the main goal of researchers. In this article, equal channel multi angular pressing (ECMAP) process as one of the most appealing severe plastic deformation (SPD) methods on production of ultra-fine grained (UFG) materials studied. Two main routes A and C investigated by FEM and compared with each other from differ...

In this study, the influence and optimization of the factors of a non-formaldehyde resin finishing process on cotton fabric using a Taguchi-based grey relational analysis were experimentally investigated. An L27 orthogonal array was selected for five parameters and three levels by applying Taguchi's design of experiments. The Taguchi technique was coupled with a grey relational analysis to obta...
