A series of experiments were designed to utilize the Taguchi method for investigating the effects of important parameters on the synthesis of NaX zeolite and to find the best conditions of synthesis. An L9 orthogonal design of Taguchi approach was applied to design experiments consisting of 9 trails. The effect of molar composition, including SiO2/Al2O3 and Na2O/Al2O3 ratios, and the crystalliz...

abstract: the aim of this research is to propose a new approach of kansei engineering, kano model and taguchi design of experiments to identify, categorize and prioritize customersʹ emotional needs (kansei) in the automotive industry in order to more customer satisfaction. to achieve the above aim, first customersʹ kansei words identified and screened; then these words classified based on kano ...

In this paper we propose the use of design capability indices for use in robust design. These indices allow the design requirements to vary within a certain range. Design capability indices are based on process capability indices from statistical process control and provide an alternate approach to the use of Taguchi’s signal-to-noise ratio which is often used for robust design. Successful impl...

In the measurement process, there are many parameters affecting the measurement results: the influence of the probe system [3,5,7,15,10,16,17,19,21], material stiffness of measured workpiece [7], the calibration of the probe with a reference sphere [3], the thermal effects [14]. We want to obtain the limits of a measurement methodology to be able to validate a result. The study is applied to a ...

for all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. in the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by psychrobacter sp. csw4 was investigated by means of taguchi approach and box-behnken statistical design under resting cell conditions. taguchi desi...

Drilling thrust force calculations require a large amount of experimental work, which can be greatly reduced, since an extensively validated CAD-based approach, using the DRILL3D software application, has become available. DRILL3D calculates the thrust force of both the cutting areas of the tool (main edges and chisel edge) simultaneously, which means that every simulation can substitute two se...

Every engineering design is subject to variations that can arise from a variety of sources, including manufacturing operations, variations in material properties, and the operating environment. When variations are ignored, non robust designs can result, which are expensive to produce or fail in service. The concept of robust design may be first used by Taguchi. He introduced this concept to imp...

With the growing commercialization of watermarking techniques in various application scenarios it has become increasingly important to quantify the performance of watermarking products. The quantification of relative merits of various products is not only essential in enabling further adoption of the technology by society as a whole, but will also drive the industry to develop testing plans/met...

Machining operations are involv3ed in many manufacturing industries. Turning process is one of the most fundamental cutting processes. Cutting used in metal cutting. Surface finish and dimensional tolerances are used to determine quality of product and are the important quality attributes of turned product. In the present paper of investigation the experimental work has been employed for the op...
