Recently 304 stainless steel finds many applications like Automotive, Aerospace, Nuclear, Chemical and Cryogenics. The cylindrical grinding parameters on 304 stainless steel are conducted using Taguchi design of experiments of L9 orthogonal array was selected with 3 levels with 3 factors and output parameter of Surface Roughness is measured. The quality of the surface describes the relationship...

Dimensional distortion occurs due to the thermal and transformation stresses formed during the heat treatment processes. Taguchi and Factorial design of experiment concepts were applied to optimize the operating variables involved in the gas carburising and induction hardening processes so as to minimize the geometrical distortions. Experimental data obtained for the materials EN353, EN351, AIS...

In this study, the effects of different welding parameters applied during laser AA2024 aluminum alloy materials on tensile strength were investigated and their optimizations made using Taguchi ANOVA methods to obtain most suitable parameters. The variable such as power, pulse duration, beam power density energy used in study. As a result, it was concluded that lowest obtained when 1800 W 5 ms 6...

This study investigated the multi-optimization of turning process on AISI1045 steel material with CNMG cutting tool for an optimal parametric combination to yield minimum surfaces roughness maximum MRR using a Grey relational analysis (GRA) and Taguchi method. In view fact, that traditional method can’t solve multi-objective optimization problem: To overcome this limitations relation theory has...

Background: Hydrocarbons degradation is principally achieved by microorganisms in natural environments. The extent of hydrocarbons biodegradation is mainly conditioned by environmental factors and its success depends on the optimal condition for the crude oil degrading isolates. Objectives: The aims of the current study was to isolate and identify crude oil degrading bacterium from surface sed...

The purpose of this paper is to present an integrated approach for improving the quality characteristics of the injection molded part (Honda Upper Part) being manufactured at manufacturing industry (Pakistan), where the rejection rate for Honda upper part was on ramp due to sink marks defects. The proposed integrated approach embraces the concept of Design of Experiments (Taguchi Approach) and ...

We present an optimization procedure that uses the Taguchi method to maximize the mean stiffness and workspace of a redundantly actuated parallel mechanism at the same time. The Taguchi method is used to separate the more influential and controllable variables from the less influential ones among kinematic parameters in workspace analysis and stiffness analysis. In the first stage of optimizati...

background and objective: microbial protein production can resolve one of the major world challenges, i.e. lack of protein sources. candida tropicalis growth was investigated to specify a medium to reach the highest cell proliferation and protein production. material and methods: fractional factorial design and the index of signal to noise ratio were applied for optimization of microbial protei...

Girth welded replica of API X70M material have been produced on NG-GMAW welding technique. The particular area interest is to develop suitable girth process parameter using NGGMAW. major aim the work was replicate welds having tensile strength between 650 and 680 MPa. Design Experiment (DoE) method by Taguchi design, some selected processes adopted. Two parameters (factors) – arc voltage wire f...
