AI Technical Summary

Benefits of technology

The technology described in this patented describes an automated way to determine if there are any abnormalities or variations in machinery's performance caused due to their periodic movements during operation. This helps identify causes like excessive wear or damage from overload conditions before they become more severe than usual.

Problems solved by technology

This patents discuss how faulty machining operations may lead to reduced productivity due to poor quality control caused by unstable rotation rates during certain stages of milling processes. These issues include decreased lifespan of machine tools (rotors) and bearing damage. Current techniques involve measuring static and dynamic properties like frequency and force levels, identifying potential causes of defects, predicting their progress towards further deteriorated conditions, and developing models based upon them. However, existing methods require significant human labor input and result in imprecise estimates of machine status and component characteristics.
