Abstract

본 발명은 공작기계의 작동상태나 다양한 공작기계의 종류에 따라 공구측정유닛에 의해 측정된 기준공구의 공구 끝단의 Z방향 또는 Y방향의 변위데이터 또는 가공된 소재의 가공부를 측정하여 산출된 공작기계의 열변위 데이터와, 온도측정유닛에 의해 측정된 온도 데이터에 의해 실시간으로 현재 공작기계의 열변위 상태에 최적화될 수 있도록 공작기계의 열변위 보정식의 보정 파라메터를 자동으로 변환하여 열변위에 따른 가공오차를 최소화하여 공작기계의 가공정밀도를 향상시킬 수 있는 공작기계의 열변위 보정 파라메터 자동 변환 장치 및 변환 방법에 관한 것이다.
