In the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. In this study, a series of compression tests were simulated using Abaqus software. In this study, it has been employed the Taguchi method to design experiments by the factor...

This paper aims at optimization of process parameters for gas tungsten arc welding (GTAW) of sheet samples of Aluminium alloy AA1100 using AC wave with Argon as inert gas. Tensile properties of parent and welded specimens were determined as per ASTM-E8M standard. Taguchi approach was applied to determine most influential control parameters which will yield better tensile strength of the joints ...

The effects of cutting tool coating material and cutting speed on cutting forces and surface roughness were investigated by Taguchi experimental design. Main cutting force, Fz is considered as a criterion. The effects of machining parameters were investigated using Taguchi L18 orthogonal array. Optimal cutting conditions were determined using the signal-to-noise (S/N) ratio which is calculated ...

The objective of this work is to optimize the control parameters of the direct injection (DI) single cylinder diesel engine with respect to NOx (Oxides of Nitrogen) and fuel emissions through experimental investigations and Taguchi method. A single cylinder 5.2 kW diesel engine was selected for this experiment. Five parameters such as clearance volume, valve opening pressure, nozzle-hole diamet...

The purpose of the present investigation is to compare the statistically controlled machining solution of titanium alloys using ultrasonic machining (USM). In this study, the previously developed Taguchi model for USM of titanium and its alloys has been investigated and compared. Relationships between the material removal rate, tool wear rate, surface roughness and other controllable machining ...

This paper focused on evaluation of machining parameters influencing thrust force during drilling of Al–SiC–Gr metal matrix composites using multifaceted carbide drills. There are three machining parameters i.e. Spindle speed, Feed rate, Drill diameter. Experiments are conducted on a vertical machining centre using Taguchi design of experiments. Taguchi orthogonal array is designed with three l...

Many factors may influence the successful development of software (SW). Most practitioners, however, tend to use their own preferred methods—some ad hoc—for this task. This paper reviews recent attempts of using orthogonal array (OA) experiments to determine the effect of various influencing factors and then their optimum settings to reduce errors in the SW created. Genichi Taguchi popularized ...

In the past few decades, there is increasing trend to use products from natural resources. Dyes obtained from natural sources are among such products. The present research mainly focuses on optimization of extraction conditions during a natural dye extraction from the flower petals of a tree ‘Flame of Forest’. Taguchi technique was employed for optimization of the parameters namely raw dyestuff...

  Background:The dynamic binding capacity (DBC) of a chromatography matrix in protein purification is the amount of the total protein absorbed into the matrix, before occurrence of a significant break in the breakthrough curve. Optimization of the process criteria for maximum DBC avoids extra process scale-up and reduces ...
