Abstract:
1. A machining center with on-line vibration detection/adjustment ability, comprising: a machine frame, comprising a computer numerical control (CNC) unit, a carrier module, a spindle module, a feeding module, a spindle override interface, and a feedrate override interface, wherein the carrier module, the spindle module, the feeding module, the spindle override interface, and the feedrate override interface are all respectively connected to the CNC unit; at least one vibration sensor, disposed on the carrier module and thus generating at least one vibration signal accordingly; and a vibration signal processor, electrically connected respectively to the at least one vibration sensor, the spindle override interface, the feedrate override interface and an inverter of the spindle module, wherein during a machining process, the vibration signal processor receives the at least one vibration signal from the at least one vibration sensor and a load signal from the inverter, and performs a calculation to generate a speed adjustment signal and a feedrate adjustment signal, the spindle override interface or the inverter receives the speed adjustment signal and automatically adjusts a speed of the spindle, and the feedrate override interface receives the feedrate adjustment signal and automatically adjusts a feedrate of the feeding module.
