Taguchi Orthogonal Design

This paper investigates the application of a Taguchi method to reduce warpage problem dealing with process parameters during production of bonding sheets. For this purpose, analysis was carried out by utilizing a combination of process parameters based on a two-level L12 Taguchi orthogonal design. The signal-to-noise and the analysis of variance are used to find the optimum levels and to indicate the impact of the process parameters on warpage. The results show that the method can reduce warpage by about 94%, and a verification test is also conducted to prove its effectiveness after the optimum levels of process parameters are determined. It can thus be concluded that this Taguchi method is suitable to solve the quality problems that occur due to warpage.

This study is focused on the effects of process parameters in plastic injection molding towards shrinkage and warpage problem of High Density Polyethylene (HDPE) specimen. The aim was to identify the main effects of different process parameters on warpage and shrinkage defects via numerical simulation software and experimental validation. Series of simulations were carried out using Cadmould 3D-F in order to utilize the combination of process parameters based on three level of L9 Taguchi orthogonal design. The Signal to Noise (S/N) ratio and the Analysis of Variance (ANOVA) were used to optimize the levels and to point out the impact of the process parameters on warpage and shrinkage. From the results, it showed that the most affected parameter on the warpage and shrinkage is packing time, with the P value of 48.93%, followed by melting temperature with 40.58%. The filling time and packing pressure were not a significant factor because they only contribute 7.30% and 3.19% of P value, respectively.

Optimization of process conditions in oriented strand board (OSB) manufacturing is a very important issue for both reducing cost and improving the quality of panels. Taguchi experimental design technique was applied to determination and optimization of the most influential controlling parameters of OSB panels such as press condition (pressure-time-temperature) and the ratio of adhesive parameters on modulus of elasticity (MOE). The value of the MOE is one of the very important mechanical properties of OSB panels. For this purpose, several experiments were conducted according to Taguchi L27 orthogonal design. The signal-to-noise (S/N) and the analysis of variance (ANOVA) were used to find the optimum levels and to indicate the impact of the controlling parameters on MOE. A verification test was also performed to prove the effectiveness of Taguchi technique. Since the predicted and the measured values were very close to each other, it was concluded that the Taguchi method was very successful in the optimization of effective parameters in OSB’s manufacturing.

Taguchi Orthogonal Design

The objective of this paper is to generate a mathematical model in order to minimize the value of surface roughness (Ra) through EDM by constructing an objective function consisting of combination of process parameters. Taguchi orthogonal design method of experiments with three process parameters viz., current, pulse-on-rate, pulse-off-rate were used to generate 25 numbers of experiments L25 at five levels. Experiments were carried out in Electronica S50 (CNC) EDM. Data obtained for performance measurement was subjected regression analysis using ANOVA. Equation was obtained for the surface roughness as a function of current, pulse-on rate, pulse-off-rate.It is found that discharge current, pulse-on-rate, and pulse-off-rate have significant effect on the Ra. Higher values of current and pulse-on-rate increased surface roughness. Lower current, lower pulse-on-rate and relatively higher pulse-off-rate produced a better surface finish.

Taguchi Orthogonal Design

In this paper, the authors present an experimental study of roughness characteristics of electroless Ni-B coatings and optimization of the coating process parameters based on L27 Taguchi orthogonal design. Three coating process parameters are considered viz. bath temperature, reducing agent concentration, and nickel source concentration. It is observed that concentration of reducing agent together with bath temperature play a vital role in controlling the roughness characteristics of the coatings. The analysis yields the optimum coating parameter combination for minimum roughness. A reduction of about 15% is observed in roughness at the optimal condition compared to the initial condition. The microstructure, composition, and the phase content of the coating are also studied with the help of scanning electron microscopes energy dispersive X-ray analysis, and X-ray diffraction analysis, respectively.

Taguchi Orthogonal Design

The present work deals with the synthesis of chemically deposited nickel–phosphorous (Ni–P) coating on copper substrate. The process parameters are optimized for maximum hardness based on L[Formula: see text] Taguchi orthogonal design with three process parameters, viz., bath temperature, concentration of nickel Sulphate (a nickel source) and concentration of sodium hypophosphite (a reducing agent), respectively. This is considered and fitted into an L[Formula: see text] orthogonal array (OA) to find out the optimized condition for improved hardness of the coating. The optimized results were obtained from 35[Formula: see text]g/L of Nickel Sulphate, 20[Formula: see text]g/L of Sodium Hypophosphite and 90∘C of temperature. Analysis of variance (ANOVA) was performed to determine the significance of the individual process parameters. ANOVA showed that the factor Nickel Sulphate, the interaction between Sodium Hypophosphite and Temperature were significant in determining the hardness of the coating deposited in the optimized condition. The surface morphology, compositional and phase structure analysis of optimized sample are conducted with the help of scanning electron microscope (SEM), energy-dispersive X-ray analysis and X-ray diffraction (XRD) analyzer, respectively.

Abstract A common problem faced in fabric manufacturing is the production of inconsistent fabric width on shuttleless looms in spite of the same fabric specifications. Weft-wise crimp controls the fabric width and it depends on a number of factors, including warp tension, temple type, fabric take-up pressing tension and loom working width. The aim of this study is to investigate the effect of these parameters on the fabric width produced. Taguchi’s orthogonal design was used to optimise the weaving parameters for obtaining controlled fabric width. On the basis of signal to noise ratios, it could be concluded that controlled fabric width could be produced using medium temple type and intense take-up pressing tension at relatively lower warp tension and smaller loom working width. The analysis of variance revealed that temple needle size was the most significant factor affecting the fabric width, followed by loom working width and warp tension, whereas take-up pressing tension was least significant of all the factors investigated in the study.
