토크부하 공급장치를 이용한 가상 2축 이송계 평가

This paper introduces a torque load supplier to evaluate control errors of a virtual 2-axis feeding unit. The torque load supplier makes a various torque loads which substitute for real physical loads such as a friction force, cutting force and inertia force in a machine tools. Therefore unwanted disturbances can be eliminated in the evaluation. Contour error in a virtual 2-axis feeding unit is evaluated using proposed torque suppliers.
