Abstract. The complexity and precision requirements of NC (Numerical Control) machining have become increasingly high due to the rapid changes of production capability and functionality [5]. NC machining shops are facing more and more thin-walled parts with freeform surfaces and other complex machining structures. These parts are easy to deform during machining. Besides, cutting tool wear and cutting tool breakage always exist during machining. The occurrence of these machining conditions will affect the quality of products and even cause scraps. Since production cost is crucial for enterprises in global competition environment, they are enforced to improve their competition capability by advanced machining techniques. Machining condition monitoring is proved to be an effective way to improve machining quality. Basically, there are two different ways to monitor machining conditions: locally and remotely. Each of them has its advantages and disadvantages. The local monitoring is intuitive for the machine tool operators to observe the real time machining conditions and to take corresponding actions, but limited by the knowledge and experience of the operators, as complex machining conditions can only be handled by experts.
