초록

지금까지 금형의 표면관리를 위해 단순 현미경이나 표면 거칠기 측정기를 이용한 측정방법들은 구조적인 문제로 산업현장에서 적용하는 데 효율성이 떨어진다. 이에 따라 장소에 구별 없이 다양한 크기의 금형 측정과 품질관리 효율성을 높일 수 있는 측정시스템 및 분석시스템은 매우 필요하다. 본 연구는 이와 같은 필요성을 만족시키기 위한 현장맞춤형 이동식 표면측정 시스템 개발을 목표로 수행하였다. 측정시스템은 지지대(Base), 몸체(Body), 광학계(Opticalsystem)등 3부분으로 분리할 수 있도록 기구적으로 설계 및 제작하였다. 측정시스템의 실험결과 표면거칠기는 94.9~99.9%의 정확성을 나타냈으며, 원의 측정 값에 대한 편차는 $2{\mu}m$ 이내로 신뢰성을 확보하였다.

Existing measurement methods using microscopes or surface roughness measurement instruments for surface control in manufacturing die are low in their efficiency when they are applied in industrial fields due to structural problems. Therefore, it is very important to develop a measurement and analysis system which can enhance efficiency in the measurement of different-sized manufacturing dies and provide quality control regardless of location. This study aimed at the development of a portable surface measurement system to satisfy this need. This measurement system was designed and manufactured in such a way as to divide it into three parts: the Base, the Body, and the Optical system. As a result of testing the system, the surface roughness was measured with an accuracy between 94.9 and 99.9%, and the deviation in the measurement value of a circle was within $2{\mu}m$.
