Method to Control Crimping Processes Using Ultrasonic Transmission Analysis

[摘要] A method of crimping wires includes positioning a wire/terminal combination between first and second crimp forming tools. A force is applied to the crimp forming tools to deform the wire/terminal combination. The method further includes measuring ultrasonic energy that is transmitted across the wire/terminal combination as the terminal is being deformed. A rate of change of the magnitude of the ultrasonic energy is also determined as the terminal is being deformed. The crimping process is terminated if the rate of change of the magnitude of the ultrasonic energy falls below a predefined threshold level. Data gathered during the crimping process can also be utilized to determine if a faulty crimp has occurred.
