摘要
利用正交实验方法,对影响跟随误差大小的因素进行优先排序,找出关键影响因素;通过实验,分析并得出关键影响因素与跟随误差之间的关系,利用此关系提出一种跟随误差报警阈值的动态计算方法,能根据进给速度实时的计算跟随误差报警阈值。与国产数控系统中传统的以静态参数设置跟随误差报警阈值相比,该方法能减少误报次数,保证数控加工精度。
Prioritization the factors was made which affected the value of tracking error using the orthogonal test,and the key factors were found. The relationship between key factors and tracking error was analyzed through test,and a dynamic calculation method for tracking error alarm threshold was raised using the relationship,which could calculate the alarm threshold according to the feed speed in real-time. As compared with the traditional method which used static parameters to set tracking error alarm threshold in domestic numercial control( NC) system,it can reduce the number of false alarm and assure the NC machining accuracy.
