Vibration balancing analysis of a dual face mill eccentric grinder machine head.

摘要

Balancing of machinery is a well known technical aspect of engineering which is practiced throughout the world. Many studies have been performed to optimize the models and methods used to make rotor balancing faster and more efficient. This thesis deals with the unique problems associated with the balancing of eccentrically designed spindles for the machine tool industry. Cobra Machine Tool Limited has designed and patented the newest form of combination face mill and grinder operation in North America. The study performed in this analysis provides a benchmark for further vibration studies by the company in the future.; Standard vibration measurement equipment, available at the University of Windsor, was used to develop a testing and balancing procedure for this specific machining head and to demonstrate the method to others in the field. The methods employed as well as the final balancing procedures are outlined in the study for various areas of interest.; The conclusions for the study were based on the in situ, balancing performed at Cobra Machine Tool for the prototype machine. Engineering design changes have been identified that will make any subsequent machines produced in the future, operate more smoothly and efficiently than the prototype machine. Other studies relating noise and vibration measurements and dynamic modeling, have been included for the completeness of the study.
