Title: | Experimental analysis and FEM modelling of a cutting tool vibrations | Authors: | Antić, Aco Zeljkovć M. Petrović P. Živković, Aleksandar Hodolč J. |
Issue Date: | 1-Apr-2012 | Journal: | Strojarstvo | Abstract: | Presented in this paper is a comparative analysis of vibrations, measured during machining process and modelled by FEM. Moreover, microscopic structure of chip cross section was analyzed in order to establish the frequency of lamellae generation and its influence on the total level of vibrations of the cutting tool. Based on the results thus obtained, a method was proposed which allows determination of tool wear degree through separation of reliable indicators from the high-frequency spectrum of the measured vibration signals. This investigation showed that the change of chip segmentation frequency significantly influences the output vibration signal within the high-frequency spectrum, and is a function of tool wear degree. | URI: | https://open.uns.ac.rs/handle/123456789/9514 | ISSN: | 5621887 |
