The multiobjective design of digital filters using the powerful Taguchi optimization technique is considered in this paper. This relatively new optimization tool has been recently introduced to the field of engineering and is based on orthogonal arrays. It is characterized by its robustness, immunity to local optima trapping, relative fast convergence and ease of implementation. The objectives ...
This paper presents the optimization of high speed milling process parameters with respect to the surface roughness of samples and the study of the Taguchi design application to surface quality in a CNC end milling operation. The Taguchi design is an efficient and effective experimental method in which a response variable can be optimized given various control factors using fewer resources than...
The theoretical foundations of Taguchi Methods were laid out by Genichi Taguchi, a Japanese engineer who began working for the telecommunications company, ECL (Electrical Communications Lab, a part of NT&T), in 1950’s. After World War II, his team was involved in the design of telephone system components, and successfully produced designs that performed better than their main rivals, Bell Labs,...
in this research work with the aid of tagouchi experimental design and rawing of interaction curves with minitab software, the best rotor speed and dump temperature of mixing for physico-mechanical and rheological properties of the rubber compound with three mixing steps was obtained. moreover by plotting the mean curves in excel worksheet, the dependency of properties on rotor speed, dump temp...
the research aimed to apply the taguchi method for techno-economical evaluation of cr+6 removal using the electro-coagulation process with the aid of two different coagulants (fecl3 and pac). taguchi orthogonal array l27 (313) was applied for analyzing the effect of four variables including initial ph, reaction time, current density and coagulant types in an attempt to improve the chromium remo...
surface roughness of engineering parts is very significant property that effectively influences on the wear and fatigue strength. there are many methods for improving surface quality of engineering parts such as grinding, lapping and honing. one of the methods for improving surface quality is roller burnishing. roller burnishing improves surface quality of engineering parts by means of cold wor...
Background and purpose: Taguchi method is a powerful design in experimental studies. This method, with the minimum number of test factors affecting the process, will save cost and time. This study was done using the Taguchi method to optimize the adsorption of fluoride from aqueous solutions by an adsorbent prepared from marble powder. Material and methods: Marble powder was supplied from Hama...
The Taguchi design of experiments was used to test the relative importance of medium components and environmental factors on poly(β-hydroxybutyrate)(PHB) production by Ralstonia eutropha. The optimum condition was obtained as: fructose concentration, 15 g/L; C/N ratio, 7.4; agitation speed 200 rpm; culture time, 40 h; temperature, 25 ° C; seed age, 15 h. At optimu...
The current essay analyzes the anti-corrosion properties of epoxy primers including anti-corrosion pigment calcium hydrogen orthophosphate and hydrophobic nano silica with various percentages optimized by Taguchi experimental design. The impact of influential factors such as the percentage of anti-corrosion pigments, percentage of nano silica and pigment to binder ratio on anti-corrosion proper...
BACKGROUND Enzymatic hydrolysis of lactose is one of the most important biotechnological processes in the food industry, which is accomplished by enzyme β-galactosidase (β-gal, β-D-galactoside galactohydrolase, EC 3.2.1.23), trivial called lactase. Orthogonal arrays design is an appropriate option for the optimization of biotechnological processes for the production of microbial enzymes. METH...
