Development of an intelligent high-speed machining center

This paper describes a method for constructing an intelligent, high-speed machining system. According to the stability lobe diagram theory, there may exist a wide, stable cutting area at high spindle speeds. When cutting in this regime, it is possible to realize high productivity and efficiency and produce high quality products. On the other hand, when the spindle speed is high, the power consumption of the spindle motor is high and the prevention and control of thermal deformation is crucial. Furthermore, a machining state monitoring method in high spindle speed area should be established. The developed system has the following features: (1) active thermal deformation compensation function, (2) a real-time machining state judging function, and (3) a remote operation function using a computer network.
