To meet the need for trained work force from the industries, industry-oriented education for students majoring in die & mold in university level is required. If the new university graduates with creativity and high technology could be put right into the work places without training at the work sites, that will lead to remove the wasting factor in education and reinforce the competitiveness of Korea's technology power. Industries would be satisfied with the trained workforce from universities and the rate of employment will be increased. To meet the needs from industries and universities, die & mold design engineering curriculum tailored for industries is developed.

This study is performed for investigating the effects of stripping and counter punching forces on shearing characteristics in fine blanking of T-shaped products, such as camber, burr-height and dimensional accuracy, etc by experiments. Conventional hydraulic press is used for experiments so that both the stripping force and counter punching force can be arbitrarily adjusted by another hydraulic unit connected to the fine blanking die. Specimens are selected as hot rolled steel sheet and carbon steel sheet commonly used in auto- mobile company. Based on the experimental results, both the dimensional accuracy and the burr height are not influenced by the stripping and counter punching forces, wherease the camber height representing dish- shaped deflection is much influenced by them, it can be seen through this study that the finely cut surface of T-shaped blank can be obtained even in conventional hydraulic press if additional equipments and specially designed die are employed.

오늘날, 플라스틱 사출성형용 금형(Injection Molding)산업은 플라스틱의 수요가 급증함과 아울러 매년 20∼30％의 성장율로 급속히 발전하고 있지만, 이의 생산은 대부분 중소기업에 집중되어 아직도 수동적인 설계 및 생산에서 벗어나지 못하고 있고, 대기업에서는 우리표준에 맞지 않는 값비싼 외국의 “금형설계용 CAD 시스템(Computer Aided Design System)”을 도입하여 금형을 설계, 제작하고있는 설정이다.(중략)

CRT용 Glass 산업의 경우, 금형 및 유리의 온도는 매우 중요한 변수이다. 이 온도는 상온에서 출발한 금형이 반복되는 Heat Cycle을 거치면서 안정화 상태로 이르게 되는 과정을 거치면서 결정된다. 이때 안정화되는 금형의 온도분포에 의해 제품의 품질이 결정됨에 따라, 불량이 발생할 경우, 안정화 시간 및 금형수정 Cost 증가 등 매우 큰 손실이 야기된다. 이에 본 연구는 CAE를 통하여 상기 Heat Cycle의 해석과정 중에서, I-DEAS의 MACRO인 "Program file"을 이용하여 Modeling 및 Meshing을 수행하여 단시간 내 정확한 Preprocessing을 통해 유동 및 열 해석에 적용하는 자동화 프로그램을 개발하였다.

This paper describes a hierarchical structure for feature definition and classification, and feature representation method based on frame structure for process planning of prismatic machined components of injection mold. The concept of Volume Removal Directions and Vertical Faces is proposed to develop a method to define and to classify features for components of injection mold systematically. A method for classifying features by the combination of volume removal directions and vertical faces is developed, and also a feature representation method by using frame structure to represent design and manufacturing information is presented.

디스플레이 산업은 우리나라의 대표적인 주력산업으로서 일본, 대만 등의 경쟁국들을 압도하고 있으며, 특히 LCD 분야는 우리나라가 최근의 대형화 및 고급화 경향을 선도하고 있다. LCD의 핵심 모듈인 BLU(Back Light Unit)에 사용되는 프리즘시트를 생산하기 위해 대면적 롤금형이 가장 많이 사용되고 있으며, 향후 도광판, 확산판 등으로 그 응용처가 확산될 것으로 기대되고 있다.

This study is designed to review the current status of the National Technical Qualification(NTQ) system in the field of die & mold, which is focused on deficiencies of the regulatory system and qualities of die & mold professionals including the master craftsman, engineer, industrial engineer and craftsman. And it is also the purpose of this study to suggest improvement strategies for the NTQ system in the field of the die & mold. This study analyze the NTQ system for the die & mold technologies or skills based on the role model which is matched their business demands, and prepares the authority(such as Human Resources Development Service of Korea) for NTQ creation, combination, abolition, setting questions, and standards correction with priority given to die & mold industry and NTQ. It also offers elective options to reshuffle NTQs through focus group interview by experts.
