一种简易的数控机床圆度误差在线测量系统

摘要

利用FANUC 0i-MC数控系统的用户宏程序开发适用于加工中心的圆度误差在线测量系统.在不增加专用测量装置的条件下 ,将数控机床原有的功能加以扩展 ,使其具有辅助测量功能.通过寻边器来实现在数控机床上对工件圆度误差的检测 ,直观显示测量结果.实验结果表明:该方法简便、准确 ,可以避免多次装夹引起的误差 ,提高了效率 ,有较好的实用价值.%The numerical control system FANUC 0i-MC user macro program was used to develop the roundness error online measure-ment system for the machining center .Under the condition without increasing special measuring device ,the functions of numerical control machine tool were extended with auxiliary measurements .Using the edge finder to detect the workpiece roundness error in numerical control machine tool ,the measurement results were displayed visually .Experiment results show that the method is easy , accurate .The machine waiting time is shortened and efficiency is improved .It has a good practical value .
