摘要： A machine or autonomous system includes a diagnostic controller and is configured to perform a method for monitoring health of a machine. The method includes monitoring a set of first electrical signals indicative of control of a motor of the machine while the machine is operated in a first autonomous mode, determining that an abnormal operating condition has occurred in response to the set of first electrical signals meeting a first criteria, having the machine operate in a test mode in response to the determination that the abnormal operating condition has occurred, monitoring a set of second electrical signals indicative of control of the motor during the test mode, and determining a fault condition in response to the set of second electrical signals meeting a second criteria.

摘要： This disclosure is generally directed to 3D tolerance analysis. In one exemplary method, a combination of a variation analysis procedure and a finite element analysis (FEA) procedure is executed by a computer. The variation analysis procedure involves determining a first simulated force for effecting a mating between a first surface of a first part and a first surface of a second part. A first set of deformation parameters is determined by applying the first simulated force to the first surface of the first part. The FEA procedure involves determining a second simulated force for effecting the mating between the two surfaces based on one or more assembly loads. A second set of deformation parameters is determined by applying the second simulated force to the first surface of the first part. Various deformation parameters of the mated assembly can be obtained by combining the first and second set of deformation parameters.

摘要： A method of measuring quality in a machining operation of a device includes measuring lost motion for at least one axis of the device during the machining operation, calculating a spindle lag of a spindle of the device during the machining operation, determining a lost motion deviation, determining a spindle lag deviation, and identifying a machining defect based on the lost motion deviation coinciding with the spindle lag deviation.
