摘要： A method includes obtaining stamping system data from a stamping system data controller and vibration data from one or more vibration sensors disposed at the conduit; selecting a baseline vibration threshold and a frequency filter from among a plurality of frequency filters based on the stamping system data; generating a plurality of measured vibration values based on the vibration data and the frequency filter, where each measured vibration value from among the plurality of measured vibration values is associated with a given iteration from among a plurality of iterations of a stamping process; determining whether the conduit is in an obstructed state based on a comparison between a set of measured vibration values from among the plurality of measured vibration values and the baseline vibration threshold; and performing a corrective action in response to the conduit being in the obstructed state.

摘要： The present disclosure generally describes a method for processing a workpiece in a machine, where the method determines an offset of the machine and adjusts for the offset during production operation. In one form, the method includes logging offset data of the machine over a period of operational time having varying thermal conditions, and comparing the logged offset data against a thermal model, where the thermal model is generated based on a probing routine and dry cycling for a plurality of test cycles on a calibration artifact. Based on the comparing, the method estimates offsets for the machine and adjusts offsets of the machine during operation.

摘要： The present disclosure is directed toward a diagnostic method for a spindle arm of a machine. The method includes rotating the spindle arm of the machine at a first rotational speed, and acquiring, from an accelerometer, data indicative of a vibrational response of the spindle arm operating at the first rotational speed. The accelerometer is disposed along the spindle arm. The method further includes converting the vibrational response to a frequency based response to obtain a first frequency response, determining whether an amplitude of the first frequency response exceeds a diagnostic threshold, and performing a designated correction on the machine in response to the frequency response exceeding the diagnostic threshold.

摘要： The present disclosure is directed toward a method for monitoring health of a machining tool operable in a machining state to form a workpiece and a non-machining state. The method includes determining whether a machine health routine is to be performed based on a machine health record stored by the control system, and retrieving a non-machining cyclic schedule, in response to the machine health routine having to be performed, where the non-machining cyclic schedule defines a timetable for performing one or more maintenance routines. The method further includes identifying a primary maintenance routine from among the one or more maintenance routines based on the non-machining cyclic schedule, and scheduling the machine health routine with the primary maintenance routine.
