摘要

摘要: 五坐标加工中心的主轴摆长是实现五坐标机床自动跟踪的关键参数，其确定值的精度直接影响加工中心的加工精度。提出一种主轴摆动式五坐标加工中心摆长的测定方法，其原理是机床坐标值的实际变动量应与通过摆长、主轴摆动角度之间几何关系计算出的坐标值变动量相符。与传统测量方法进行了比较，证明所提方法精度高于传统方法，并且实用、可靠。

Abstract: The pendulum length is a key parameter which achieves automatic tracking about 5-axis machining center. The processing precision of machining center is directly influenced by the pendulum length. A method for measuring the pendulum length about tool axis pendulum type machining center is presented, in which the principle is that actual variations of machine coordinate values should be consistent with the calculated variations according to the geometric relations between pendulum length and swing angle of tool axis. Compared with the traditional method, example demonstrates that the present precision is higher than the traditional. In addition, the method is proved to be reliable and practical.
