The purpose of this research is to establish a test model of a highly comprehensive supervision system. It will be implemented on a 200 Series Omnimill with a Flex-Mate Controller. Sensors of tool wear, tool breakage, chatter, geometric errors due to cutter deflections, and of cutter overloads will be employed. Signals from the sensors will be processed together with predictions based on inputs derived from the numerical control (NC) program and on analytical models and simulations. Using these models and information theory, corresponding corrective actions will be derived and carried out through routines implemented in the NC Controller. Thus, this system will be comprehensive in that sense that apart from the sensor signals it includes also inputs from the Computer-Aided Design (CAD)/Computer-Aided Manufacturing (CAM) system for more than just the usual cutter location path data and it includes the Controller for the execution of the corrections. Some of these corrections will permanently modify the NC program.

本研究的目的是建立一个高度综合的监督系统的测试模型。它将在200系列万能铣床上实现，并配有柔性控制器。刀具磨损、刀具断裂、颤振、刀具偏转引起的几何误差和刀具过载的传感器将被采用。来自传感器的信号将与基于来自数控（NC）程序的输入以及分析模型和模拟的预测一起处理。利用这些模型和信息论，相应的纠正措施将通过在NC控制器中执行的例程推导和执行。因此，从这个意义上说，该系统将是全面的，除了传感器信号外，它还包括来自计算机辅助设计(CAD)/计算机辅助制造（CAM）系统的输入，而不仅仅是通常的刀具位置路径数据，它还包括执行校正的控制器。其中一些修正将永久地修改NC程序。
