Development of Online Realtime Positioning Error Compensation System for CNC Machine Tools
CNC 공작기계용 온라인 실시간 위치오차 보정시스템의 개발

Abstract
The online realtime positioning error compensation system 'SKY-PACS' is developed to correct geometric errors, thermal errors and tool deflection errors induced by cutting forces on the vertical machining center. 'SKY-PACS' communicates position commands and position compensation signals with the CNC controller at 100Hz, which is CNC control frequency. So the compensation procedure can be applied during axis movement. Using 'SKY-PACS', Maximum 1 axis positioning accuracy was corrected from 5
