  • Taguchi's multi-characteristic experiments seek proper choice of levels of contollable factors which satisfy that all reponses of characteristics in a desirable range simultaneously. This aim can be achieved by response surface techniques that allow more flexible in modeling than traditional Taguchi's parameter design. In this article, a multi-response surface modeling and analysis techniques is proposed to deal with the multi-characteristic optimization problem in experimentation with Taguchi's controllable and noise factors.

  • 클러스터형의 다중 공정용 장치에 부착키 위해 제작된 콘택 산화막 식각용 공정모듈에 대한 적정 식각 공정조건을 확립하기 위해, Taguchi 방법을 활용하여 공정최적화 실험을 수행하였다. Taguchi 실험은 2회에 걸쳐 시행되었는데, 제1차 실험은 장비변수에 대한 식각공정변수의 개괄적 거동을 타진하기 위함이었고, 제2차 실험은 상세 공정조건 확립을 위해서였다. 실험 및 분석 결과 $CHF_{3}/CF_{4}$ 가스유량은 72/8sccm, 공정압력은 50 mTorr, RF 전력은 500 Watts, 자계강도는 90 Gauss일때 최적 공정 성능을 발휘함을 알 수 있다.

  • Taguchi method is a technique widely used in industries to attain a reliable quality even under existence of various noise variables. Basically, it relies on the interactions between the controllable and the noise factors. Under insignificant interactions between the design parameters and noises, the effectiveness of Taguchi methodology will be doubtful. Furthermore, existence of strong interactions among controllable factors may undermine the power of Taguchi approach. An abundant crop may be expected by a well planned Taguchi approach. A well designed set of experiments is one of the important prerequisites for its successful result. For this, we must have a clear understanding on strengths and weaknesses of Taguchi methodology together with a sound knowledge on the applicable system. This study provides some insights on Taguchi approach based on two case examples of one successful and the other unsuccessful. Eventually, this research aims to facilitate deeper understanding and right application of Taguchi methodology in industries.

  • Chip control is a major problem in automatic machining process, especially in finish turning operation. In this case, chip breaker is one of the important factors to be determined. As unbroken chips are grown. these deteriorate the surface roughness. and proces automation can not be carried out. In this study to get rid of chip curling problem while turning internal hole. optimal chip breaker is selected from the experiment. The experiment is planned with Taguchi's method that is based on the orthogonal arrary of design factors. From the response table. cutting speed, feedrate, depth of cut and tool geometry turn to be major factors affecting chip formation. Then, optimal chip breaker is selected. and this is verified as good enough for chip control from the experiment.

  • It has many variables and factors to design the friction materials for automotive brake pads. The purpose of this study is to develop the proper method for design of low-cost and to know friction characteristics of each raw materials. For the purpose of examining the effect of each major raw materials, we used the Taguchi L9(3$^4$)orthogonal matrix and 1/5 scale dynamo machine for evaluation of the friction characteristics of composite brake pads. By adapting the Taguchi method, it is easy to investigate the influence of each component in complicated composites friction materials. After analyzing the testing results by the Taguchi method, the effect of factors and levels influenced friction behavior was studied.

  • 본 고에서는 품질향상 측면보다는 실험계획법 자체에 중점을 두고 이를 소개하고자 한다. 실험게획의 일차적 목적은 어느 의미에서는 모형화 즉 반응치에 미치는 각 인자의 주효과의 교호작용 관게를 규명하는 것이라고 볼 수 있으며 방법론에서 전조합실시법과 부분실시법으로 구분할 수 있는데 부분실시법의 목적은 어떻게 하면 경제적으로 시험횟수를 최소화하되 전조합실시법의 효과를 낼 수 있는가 하는 것이다. Taguchi의 실험계획은 직교배열을 이용한 부분실시법에 근거를 두고 있다.

  • Laser photolithography technique is useful for fabricating micro-patterns of silicon wafers. In this work, the laser photolithography micromachining technique is optimized based on Taguchi method. Sensitivity analysis was performed using laser scanning speed and laser power level as the parameters. The results show that for the photoresist used in this work, a laser scan speed of $70{\mu}m/s$ at 50mW laser power gives the best result.

  • The passenger car manufacturer should meet more and more strict requirements of customers on noise and vibration problems. It is proven that the Taguchi method is a powerful tool for improving the product quality in many areas. This paper employs the Taguchi method to reduce low-frequency booming noise in a passenger car. Selection of object function is very important to minimize interaction effects in the Taguchi method. We select logarithmic-scaled sound pressure level as an object function, which is commonly used to analyze the noise and vibration signals. The optimum noise level predicted with additive-model assumption agrees well with the test results. In addition, the optimum level is lower than the initial one by about 5 dB without any adverse effects. The results show that the Taguchi method can be applied efficiently to solve the noise problem in the passenger cars.
