Machine Tool Dynamic Measurements and Diagnostic System
Abstract
Vibrations in machine tools, commonly known as chatter, often are the cause for poor machining operations and breakdown of machinery. A state-of-the- art measurement and analysis system was designed, fabricated, and implemented. The system performs real-time acquisition of raw vibration measurement data and provides analysis for preventative/predictive maintenance action. The system has been used to determine the causes for poor surface finishes occurring during metal removal processes. The implementation of the Machine Tool Dynamic Measurements and Diagnostic System into maintenance practices enables technological advantages in the following manufacturing areas: ability to quickly determine and remedy existing machine tool mechanical problems, reference-baseline vibration signature (newly acquired machine tools and existing units), assistance in maintaining ordnance dimensional and surface finish requirements, improvement in reducing machine downtime, and input for short/long-term management purposes. Keywords: Machine tools, Vibrations, Acquisition, Baselines, Dynamics, Preventive Maintenance, Spindles, Surfaces.
