  • Method for detecting and/or preventing grind burn
    Patent number: 10213898
    Abstract: The present disclosure provides a method of detecting and preventing grind burn from developing on a gear. The method includes performing acoustic emission testing while the gear is being ground during a grinding operation. The grinding wheel is evaluated during an eddy current test to detect material buildup on the grinding wheel which could cause grind burn. In addition, the method includes collecting swarf from the gear during the grinding operation and inspecting the swarf for an indication of grind burn.
    Type: Grant
    Filed: October 6, 2015
    Date of Patent: February 26, 2019
