ABSTRACT:
A device for determining the quality of a part includes a sensor for detecting a strain on a selected portion of a part forming machine. A controller utilizes the detected amount of strain to make a determination regarding the quality of a corresponding part. In one example, the sensor detects a compressive or tensile strain on a machine frame when the sensor is aligned to detect a strain parallel to a direction of a force applied during the part formation process. The controller uses one or more characteristics of the sensor output and determines whether the detected amount of strain is within an acceptable range. In one example, monitoring the strain during the formation of a plurality of acceptable parts provides information for determining the acceptable range. The disclosed arrangements allow for making part quality determinations without requiring a sensor to be “in line” with the load.
