A device and a method of monitoring a condition of a machine in real time. The method includes: interfacing an edge device with the machine; requesting a handle from a controller of the machine; querying the machine with an adapter of the edge device for a control data; and acquiring control data from one or more sensors of the machine. The method includes repeating the steps of querying the control data and acquiring the control data after a period of time at a high frequency.

An abnormality in a process is grasped and a clue for determining a cause is obtained quickly. A process management device includes: a monitoring data acquisition means, a process capability index calculation means, a process capability index transition curve calculation means, a separation determination means, a change information acquisition means, and a target change information output means. The process capability index transition curve calculation means calculates a process capability index transition curve. The separation determination means calculates a separation between a process capability index and the process capability index transition curve, and determines that the separation is abnormal when the separation is equal to or more than a predetermined threshold. The change information acquisition means acquires, when the separation is abnormal, change information representing a change regarding a process in a period from a time when an abnormality is detected to a predetermined time before the time.

Some embodiments of the present disclosure provide a method for judging four key moments in a whole process (a feeding starting moment, an idling process, a cutting starting moment, cutting, a cutting ending moment, an idling process and a feeding ending moment) of a machining step for computer numerical control machine tools. The method includes that: the feeding starting moment and ending moment are determined according to a real-time execution state of a numerical control code; input power of a spindle of a machine tool is compared in real time with idling power to determine the cutting starting moment and ending moment; and for a special machining step in which power does not change obviously in a feeding process, the cutting starting and ending moments are determined in combination with a historical statistical average time of an idling process duration and a feeding moment.
