Abstract

The three-dimensional complex curvature of the airfoil complicates the manufacture and repair of gas-turbine components. As a result of the developments in computer technology since the early 1990s, CNC-based technologies for machine tools and related programs have been increasingly applied in the gas turbine industry. In particular, fiveaxis simultaneous machines with adaptive functions have proven its excellent flexibility and productivity due to the capability in determining the 3D data from the unknown curvature. A well-organized robot system with eight-axis simultaneous control can lead to powerful standardization and high productivity. We summarize and review CNC technologies and their applications in the gas turbine industry, with a discussion of the manufacture and repair of gas turbine parts.

가스터빈 회전익이나 고정익 에어포일이 지닌 3 차원 곡면형상의 복잡성은 제조산업뿐만 아니라 재생정비 공정조차 어렵게 만드는 요인이다. CNC 기반기술을 이용한 공작기계와 공정 관련 프로그램들은 1990 년대부터 발달하기 시작한 컴퓨터 기술 덕분에 급속히 개발되면서 가스터빈 분야로 그 응용범위를 넓혀 나가고 있다. 특히 적응형 기능을 겸비한 5 축 동기 제어형 생산장비들은 유연한 공정능력과 손실된 부위의 형상 정보를 결정하는데 탁월한 성능을 보이고 있다. 8 축 동기제어가 가능하도록 구비된 로봇형 공정시스템은 매우 강력한 공정절차 표준화를 이룰 수 있게 할 뿐만 아니라 높은 생산성도 가져다 준다. 이 논문에서는 가스터빈 산업에서 CNC 기반기술의 응용현황을 검토하고, 부품 제조산업과 재생정비 산업의 공정비교와 개발사례를 통해 향후 전망을 제시한다.
