Pre-hardened steel (P20) is a widely used material in the production of moulds/dies due to less wear resistance and used for large components. In this study, minimization of surface roughness has been investigated by integrating design of experiment method, Response surface methodology (RSM) and genetic algorithm. To achieve the minimum surface roughness optimal conditions are determined. The e...

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...

Research in assembly planning can be categorised into three types of approach: graph-based, knowledgebased and artificial intelligence approaches. The main drawbacks of the above approaches are as follows: the first is time-consuming; in the second approach it is difficult to find the optimal solution; and the third approach requires a high computing efficiency. To tackle these problems, this s...

Taguchi’s robust parameter design has been widely applied to a variety of quality engineering problems; however, it is unable to deal with dynamic multiresponse owing to the increasing complexity of the product or design process. This study incorporates desirability functions into a hybrid neural network/genetic algorithm approach to optimize the parameter design of dynamic multiresponses with ...

Considerable amount of work has been devoted to the identification and quantification of contaminants in paper and paperboard for food packaging applications, particularly in papers containing recycled fibre. However, much less effort has been dedicated to the development of predictive migration models for such materials when used in contact with food. The work presented here has as main object...

In this paper, the experimental design of using the Taguchi method is employed to optimize the processing parameters in the plasma arc surface hardening process. The processing parameters evaluated are arc current, scanning velocity and carbon content of steel. In addition, other significant effects such as the relation between processing parameters are also investigated. An orthogonal array, s...

This paper presents the application of Taguchi approach in investigating the performance of mobile ad hoc networks (MANETs) with respect to drop rates. The performance of MANETs was influenced very much by the routing protocol designs and quantitative factors such as network size, terrain, pause-time, node speed, transmission range, traffic load, and packet rates. The NS-2 simulator was used fo...

EDM is a prominent non-traditional machining process, which is widely used for machining hard materials which is not possible byconventional processes. A very special aspect of this process is a surface modificationby material transfer from the tool electrode to the work-piece which is commonly known as electro discharge coating (EDC). In this work, electrode prepared with tungsten (W) and copp...

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...
