Grey relational analyses are applied to determine the suitable selection of machining parameters for Wire Electrical Discharge Machining (Wire-EDM) process. The Grey theory can provide a solution of a system in which the model is unsure or the information is incomplete. Besides, it provides an efficient solution to the uncertainty, multi-input and discrete data problem. According to the Taguchi...

In this paper, a design is presented for high-speed, high-power motor four-legged robot actuator that was optimized using the weighted sum method (WSM) based on Taguchi method, and response surface (RSM). First, output torque, torque constant, ripple, efficiency were selected as objective functions design. The sampling implemented to use mixed orthogonal array single characteristics of each fun...

a series of experiments were designed to utilize the taguchi method for investigating the effects of important parameters on the synthesis of nax zeolite and to find the best conditions of synthesis. an l9 orthogonal design of taguchi approach was applied to design experiments consisting of 9 trails. the effect of molar composition, including sio2/al2o3 and na2o/al2o3 ratios, and the crystalliz...

Abstract Friction stir welding is a solid state joining method used to join materials which cannot be joined by fusion welding. In this method, heat produced due the friction between tool and workpiece weld material. Heat input depends upon amount of caused process parameters such as rotational speed, geometry, axial force etc. present study, effect shoulder pin diameter ratio, speed on peak te...

Solidity is one of the main factors that influence performance a wind turbine. The solidity an H-Darrieus turbine optimized in terms blade number, chord length, and rotor radius to get maximum power coefficient using Taguchi L16 (4^3) array. Power values are calculated by Double Multiple Stream Tube model house built MATLAB code according orthogonal found as 0.4728 for two-bladed with length 0....

Strong non-linearity combined with the complicated rheological behaviour of polymers makes the quality characteristics of products unpredictable in plastic injection moulding. The purpose of this work is to study the mechanical properties of injection moulded polypropylene/E-glass composites. The process parameters like the melt temperature, injection pressure, packing pressure and cooling time...

An experiment was conducted to compare the effects of ultrasonic and non-ultrasonic on glass lens using rotary ultrasonic machining (RUM) technology. The primary objective of this study is to analyze the experimental results of the grinding operations using Taguchi method. Feed rate and frequency are the main process parameters to be tested in this experiment. A three-level orthogonal array tab...

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...

manufacturing process frequently employs optimization of machining parameters in order to improve product quality as well as to enhance productivity. the material removal rate is a significant indicator of the productivity and cost efficiency of the process. taguchi method has been implemented for assessing favorable (optimal) machining condition during the machining of nylon by considering thr...
