Computer aided dynamic accuracy evaluation on CNC machine tools

전산기를 이용한 CNC 공작 기계의 동적 정밀도의 평가에 대한 연구

In this paper, a new measurement system has been developed for measuring servo errors of CNC machine tools. Unlike the ball link bar method using circular path, the developed system uses two orthogonal straight paths for measurement of errors, giving relatively short test length. For position measurment, linear displacement sensor and steel cube have been designed, and the software for relevant data sampling and error evaluation has been implemented.
