摘要： A control system for evaluating residual operating life of a machine component of a machine tool includes a sensor and a control system. The sensor is disposed on the machine tool and is configured to sense movement of the machine component. The control device is configured to calculate a length of time based on a sense signal received from the sensor and sampled at a time point right after the machine component is freshly oiled, and to enable output of an alarm when determining that the length of time thus calculated is smaller than a predetermined length.

摘要： A control system for controlling oil-injection of a machine tool includes a sensor, a signal-processing device and a control device. The sensor senses movement of a machine component of the machine tool and outputs a sense signal to the signal-processing device. The signal-processing device derives analysis signals from the sense signal and sends the analysis signals to the control device. The control device determines whether to output an oiling signal to the machine tool to trigger an oiling device to oil the machine component according to an accumulated moving distance and a variation value that are calculated based on the analysis signals.
