Simulation and prediction of CO2 laser cutting of Perspex glass has been done by feed forward back propagation Artificial Neural Network (ANN). Experimental data of Taguchi orthogonal array L9 was used to train the ANN model. The simulation results were evaluated and verified with the experiment. In some cases, the prediction errors of Taguchi ANN model was larger than 10% even with Levenberg M...

The goal of this paper is to perform complex assembly tasks, using a robot assisted by a multi-axis vibrator that reduces friction and avoids jamming. An experimentbased approach using the Taguchi Method is applied to the tuning of the vibrator. The vibrators are tuned so that effects of friction and stick-slip can be minimized. Using actual assembly data and an experimental analysis method, ca...

Purpose: This study aims to examine the interaction between process parameters and bead geometry, to perform the research to predict optimal bead geometry (bead width, reinforcement height, left leg length, right leg length) through the analysis of experimental data. For this, not only linear and the curvilinear equations were developed to predict bead geometry, but also interactions between pr...

The objective of the present study is to optimize the process by applying the Taguchi method with orthogonal array robust design. Taguchi Parameter Design is a powerful and efficient method for optimizing the process, quality and performance output of manufacturing processes, thus a powerful tool for meeting this challenge. Off-line quality control is considered to be an effective approach to i...

Dr Taguchi is a Japanese engineer and an international quality consultant who has made breakthrough improvements in product and process quality through the use of statistical design of experiments (SDOE). The Taguchi method became popular in the West in the 1980s as a means to design robust products and processes. Although many companies and industries have used the method with success, the rea...

The influence of medium ingredients on extracellular dextransucrase production by a new bacterial strain Weissella confusa Cab3 (Genbank Accession Number JX649223) was evaluated using fractional factorial design of Taguchi’s orthogonal array. Four metabolism influencing factors viz. sucrose, yeast extract, K2HPO4 and Tween80 were selected to optimize dextransucrase production by W. confusa Cab3...

Technological advances have facilitated many developments in the MEMS, electrical, medical and aerospace industries in recent years. As the devices commonly found in these industries have become smaller, so the requirements for high-precision machining techniques have become ever more pressing. Nowadays, micro-machining processes are playing an important role in satisfying these requirements. A...

Optimization for enhanced phytase production by Aspergillus oryzae SBS50 in submerged fermentation was investigated using Taguchi design. In first step design, starch, beef extract, magnesium sulphate, ferrous sulphate and Tween 80 were identified as significant factors affecting phytase production. These significant factors were further optimized at four different levels using a second Taguchi...
