One of the goals of current research on machining is to provide adaptive control of metal removal operations, so that they can be performed unattended by human operators. This means that the control system must be able to correct for slowly varying conditions such as tool wear, and for sudden events such as tool breakage, formation of tangling-type chips, on-set of chatter, and other phenomena. The general approach is to use the computer to make the in-process decisions that would normally be made by a human operator. The principal investigator will study qualitative changes in the (empirical) physical models used to describe the metal cutting process. The principles of these models will be embedded in the control computer. Past and present data will be fed into the computer, which will 'adapt' the system not only by changing the processing conditions, but also, if required, by changing the process model. Analytical work will be followed by experimental evaluation.

当前机械加工研究的目标之一是提供 金属去除操作的自适应控制，使得它们可以 由人类操作员无人值守地执行。 这意味着控制 系统必须能够校正缓慢变化的条件， 工具磨损，以及突然事件，如工具断裂，形成 缠结型切屑、开始颤振和其它现象。 的 一般的方法是用计算机使过程 通常由人类操作员做出的决定。 的 主要研究者将研究 用于描述金属切削过程的（经验）物理模型。 这些模型的原理将嵌入到控件中 电脑 过去和现在的数据将被输入计算机， 将不仅通过改变处理条件来“适应"系统， 而且，如果需要，还可以通过改变过程模型。 分析工作 将进行实验评估。
