최근 항공, 금형 등 고 정밀 가공분야에서 정밀 가공에 대한 수요가 증가하면서 5축 공작기계의 사용이 증가하고 있다. 그러나 일반적으로 5 축 공작 기계는 3개의 직선 축에 2개의 선회 축이 쌓여 있기 때문에 다양 한 오차가 누적되어 정밀 가공에 영향을 미치고 있다. 장비의 5축 정밀도 를 검사하기 위하여 NAS(National Aerospace Standard)979에 기록되어진 원 추대 가공 시편은 5축 공작기계의 성능 테스트용으로 일반적인 유저에게 널리 알려지고 있다. 그러나 장비의 일반적인 가공 성능은 잘 보여주지만 공작물의 프로파일 오차로부터 기계의 기구학적 오차를 개별적으로 찾아 내는 것은 일반적으로 어렵다. 본 논문에서는 5축 공작기계의 기구학적 오차 요인을 식별하기 위하여 참고 문헌 (1)에서 제시되어진 가공 방법을 기초로 수정 제안된 가공 테 스트를 제안한다. 그리고 완성된 공작물의 기구학적 오류의 식별은 datum ball 과 Probe를 이용한 측정과 비교한다.
