An intelligent controller based on constant cutting force for 5-axis milling

In the machining, process parameters need to be monitored and adjusted automatically, which can improve production quality and reduce machining time. At present, it is mainly concentrated on the study of some algorithms about tool wearing and tool breakage, or theory modeling of interrelated models in the processing machining. The monitoring systems independent of CNC are also investigated to realize the status monitoring on external parts, which result in lower integration and difficulty in operation. Consequently, an integrated controller of five axis milling, which is modular and configurable, is established. Its composition and control flow have been introduced in detail. This controller has the ability of keeping constant cutting force, adjusting feed-rate intelligently, which is a part of CNC system. With this system it can realize the real time status monitoring in machining, and improve the work-piece's quality and efficiency in rough milling. At last, the operating principle of the intelligent algorithm in this controller has been described.
