  • Publication number: 20120243952
    Abstract: An on-line vibration detected and intelligent control apparatus for cutting process which integrated with machine tool's I/O module and a method thereof are disclosed, which can detect vibration of the machine tool during a machining process and calculate a gain, which can be a plus value or a minus value, according to the detected vibration signal. By adding the gain to the current spindle speed or the current feed rate of the machining process, an updated spindle speed or an updated feed rate is obtained so as to be used in the machining process for compensating and thus preventing the vibration of the machine tool during the machining process.

  • Patent number: 7809474
    Abstract: A protection gas control method for a non-sealed process chamber including the steps of activating a protection gas control apparatus while coupling a protection gas to a plurality of throttle valves, opening all the throttle valves for a pre-determined period of time, closing at least one of the throttle valves if the oxygen concentration in the chamber is smaller than or equal to a first target value, determining whether the oxygen concentration in the chamber is smaller than or equal to a second target value, and stopping supplying the protection gas when the temperature of the chamber is lower than a pre-determined temperature.
