During the last few years, several sheet hydroforming processes have been introduced. Despite the advantages of these methods, they have some limitations. Of the processes, the two main ones are the standard hydroforming and hydromechanical deep drawing. A new sheet hydroforming die set was proposed that has the advantages of both processes and eliminates their limitations. In this method, a po...

The specific effect of chemical and physical factors on amidase production from Geobacillus subterraneus RL-2a was investigated using design of experiments (DOE) methodology. The one-factor-at-a-time (OFAT) method was used to study the effects of carbon and nitrogen sources on amidase production. Subsequently, optimal levels of physical parameters and key media components, namely temperature, p...

Methods of designing equipment to improve quality have been developed by Taguchi. A key feature of these methods is the development of loss function, which quantifies the financial cost (loss) resulting from deviations from target dimensions. Total knee arthroplasties can fail due to prosthetic component malalignment. A Taguchi loss function for varus/valgus alignment of the prosthesis and revi...

The fuzzy regression has been found effective in modeling the relationship between the dependent variable and independent variables when a high degree of fuzziness is involved and only a few data sets are available for model building. This research, therefore, proposes an approach for optimizing multiple responses in the Taguchi method using fuzzy regression and desirability function. The stati...

In this article, the dynamic Taguchi methodology is applied to the design of a barcode scanner. The concurrent engineering process involves a team of design and manufacturing engineers engaged in both hardware and software aspects of the product. The purpose of this experimental study is to determine the correlation between the outcomes of the conventional design and Taguchi optimization. The m...

Taguchi Method is explained in brief and one of the textile processes, called spinning process, is optimised by using Taguchi method for manufacturing optimum packing density of different technologies yarns. The effect of process variables like: lap hank, card draft, draft/doublings and drafts at speed frame, ring frame, rotor and air-jet spinning machine on packing density parameters of respec...

This paper is focused on minimization of the burr height and Tool wear in drilling of Aluminium Metal Matrix Composites(AMMC) using “Desirable-Fuzzy” approach, which is developed by combining the Desirability Function Analysis and Fuzzy Logic. AMMC samples are prepared based on selected material parameters and drilling experiments are conducted on these samples as per Taguchi OA L27 which is de...

Taguchi orthogonal array design is a statistical approach that helps to overcome limitations associated with time consuming full factorial experimental design. In this study, the Taguchi orthogonal array design was applied to establish the optimum conditions for bovine serum albumin (BSA) nanocarrier (ANC) preparation. Taguchi method with L9 type of robust orthogonal array design was adopted to...

The work presents a multi response optimization approach to determine the optimal process parameters in wire electrical discharge machining process. Experiments have been conducted using six process parameters such as discharge current, pulse duration, pulse frequency, wire speed, wire tension and dielectric flow rate each at three levels for obtaining the responses like material removal rate, ...

Process capability indices are designed to describe how the process of interest can achieve to meet specification limits under a condition of statistical control. One of the capability indices is denoted as Cpm proposed by Chan, Cheng and Spiring (1988), sometimes termed the Taguchi index. The primary goal of this paper attempts to construct a confidence interval for Cpm, which measures proces...
