由于数控机床的丝杠在制造、安装上存在误差以及长期使用造成的磨损，导致螺距实际移动值与预期设定值之间存在差异。提出了螺距误差的单向补偿方法和双向补偿方法。介绍了螺距补偿的原理，包括单向补偿方法、双向补偿方法的原理；提供了一种实现单向补偿、双向补偿的设计方案；编写了简单的零件位置移动程序来测试双向补偿方法是否生效。实验结果证明，该方案能够解决数控系统中的螺距误差。

Because the manufacturing and instal ation errors and wear oflLong￣ferm use exist in the lead of NC machine tool,its ac￣tual moving position is made different from its expected moving posifion. The article puts forward the uni￣direction and bi￣direction compensation in numeric control er,introduces the principle of lead￣screw compensation, including the uni￣direction and bi￣direction compensation,then gives out one method which is used to design uni￣direction and bi￣direction compensation and edits one program which is used to test whether the bi￣direction compensation is valid or not. The result of experiment shows the lead￣screw error exist￣ing in numeric control er is solved.
