The numerical control system FANUC OiC user macro program was used to develop the cutting tool length automatic measurement procedures for the machining center. The automatic input of the cutting tool length solved the error-prone in processing cutting tool length manual input. Trial results show that the method is easy, accurate. The machine tool waiting time is shortened and efficiency is improved. It has a good practical value.%利用FANUC OiC数控系统的用户宏程序开发适用于加工中心的刀具长度自动测量的程序,且刀具长度值的自动输入解决了加工过程中刀具长度手动输入易出错的问题.试用结果表明:该方法方便、准确,缩短了机床等待时间,提高了效率,有很好的实用价值.
