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 work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...

Chitinase production by newly isolated Serratia marcescens B4A was optimized following Taguchi’sarray methods. Twenty-three bacterial isolates were screened from shrimp culture ponds in the South ofIran. A chitinase-producing bacterium was isolated based on it’s ability to utilize chitin as the sole carbonsource. The isolate designated as B4A, was identified as Serratia marces...

This paper presents a study of the Taguchi design application to optimize surface quality in damper inserted end milling operation. Maintaining good surface quality usually involves additional manufacturing cost or loss of productivity. The Taguchi design is an efficient and effective experimental method in which a response variable can be optimized, given various factors, using fewer resources...

BACKGROUND Renal transplantation is the treatment of choice for chronic renal failure. Using a suitable ureterovesical anastomosis technique can prevent most of risks for kidney graft. Extravesical ureteroneocystostomy is becoming popular in renal transplantation because of the low complication rate and technical ease. The decreased complication rate is due to limited bladder dissection and the...

In this study, the integrated Taguchi-simulated annealing (SA) approach is applied to examine the wear behaviour of silicon nitride (Si3N4)hexagonal boron nitride (hBN). Wear tests for Si3N4-hBN composite versus steel (ASTM 316L) disc were carried out for a dry sliding conditions in a so-called pin-on-disc arrangement. The tests were realized at % volume of hBN 0, 4, 8, 12, 16 in Si3N4 under th...

In this work we solve the problem of architecting a conceptual, near-term, cost-effective system of systems (SoS) to respond to small boats used by terrorists to attack maritime commerce traffic and critical shore infrastructures in the United States, by formulating the architecting problem as an assignment problem which is then solved using the orthogonal array experiment. Also known as the Ta...

background and objectives: microbial caffeine removal is a green solution for treatment of caffeinated products and agro-industrial effluents. we directed this investigation to optimizing a bio-decaffeination process with growing cultures of pseudomonas pseudoalcaligenes through taguchi methodology which is a structured statistical approach that can be lowered variations in a process through de...

Robustness is an important requirement for almost all kinds of products. In this article we show how evolutionary algorithms can be applied for robust design based on the approach of Taguchi. As an example we consider the design of multilayer optical coatings most frequently used for optical lters.
