提出一种用于测量数控机床圆运动轨迹误差的新装置———二维球杆仪 ,讨论了该仪器的误差分析和补偿。理论分析和测量试验证明 ,该仪器不仅可以测量圆轨迹点的径向误差 ,而且可以测量角度误差。
A new device for measuring the error of the circular motion of NC machine tool, a two-dimensional ballbar, is proposed. The error analysis and compensation of the instrument are discussed. Theoretical analysis and measurement tests show that the instrument can not only measure the radial error of circular track point, but also measure the angular error.
