A processing apparatus includes a processing unit for processing the workpiece, a processing quality prediction unit connected with the processing unit electrically, a signal interpretation unit connected with the processing quality prediction unit electrically, and a control unit connected with both the processing unit and the signal interpretation unit electrically, wherein when the processing unit is processing the workpiece, the processing quality prediction unit detects the processing signal and sends the signal to the signal interpretation unit, wherein when the signal interpretation unit interprets the processing signal, if there is abnormality in the processing signal, the signal interpretation unit will immediately notify the control unit to stop the processing unit from operating. Therefore, by real-time monitoring the abnormality of the processing signal and stopping suspicious operation during processing, it allows operating personnel to deal with the abnormal condition, so as to greatly reduce the defect rate of the workpiece processing.

A determination apparatus includes circuitry to receive operation information corresponding to an action being performed by a machine to be diagnosed and a detection signal of a physical quantity that changes according to the action of the machine; take out, from the detection signal, an operation detection signal indicating that the machine is operating, based on the operation information; extract feature information of the operation detection signal; select, from the feature information, particular feature information to be compared with a plurality of reference feature information; and determine a machining section of the machine in the feature information, based on the plurality of reference feature information and the particular feature information.

A processing apparatus includes a holding unit for holding a workpiece thereon, a processing unit for processing the workpiece held on the holding unit, a moving mechanism for moving the holding unit and the processing unit relatively to each other, a processed state measuring unit for measuring a processed state of the workpiece, and a controller for controlling the processing unit, the moving mechanism, and the processed state measuring unit. The controller acquires processed state information of the workpiece from the processed state measuring unit, acquires vibration information regarding vibrations that are being produced while the processed state information is acquired, links the processed state information and the vibration information that have been acquired with each other, and stores the processed state information and the vibration information that have been linked with each other.
