Automatic experimental modal analysis of milling machine tool spindles

Piotr Bąk , Krzysztof Jemielniak


Dynamic compliance of machine tool spindle is a necessary input for stability limit prediction. It can be determined by a single input–single output modal analysis, so called tap test. Despite methodology of modal analysis is well known for many years and there are several commercially available software packages supporting it, executing the experiments and evaluation of the results require both knowledge and skill. Therefore, there is a need for automation of all stages of data acquisition and signal processing to make this method applied in industry. This article presents the methodology, algorithms and software which execute all operations and analysis automatically; thus, they can be done directly on the factory floor without the involvement of highly qualified personnel. It enables completing of the tap test and obtaining proper results by an operator who do not have any knowledge on modal analysis. This article presents examples of the software application in factory floor conditions
