VIBRATION MEASUREMENT DURING MILLING BY ACOUSTIC EMISSION

Abstract

Production processes are nowadays very much challenged by the continuous improvement of productivity, the reduction of energy and ecological burden and the pursuit of the highest possible economy of the whole process in general. In order to optimize any process, it is essential that the process quality can be measured, and its behaviour adjusted ideally "just in time". In the case of machining, vibration is a major problem. This phenomenon, which always accompanies machining and especially milling, has an essentially negative impact. The aim of this article is to present the possibility of measuring vibration both with special active tool grooves from SCHUNK and indirectly with the acoustic emission sensing method. The article also deals with the nature of vibration itself as well as the comparison of both methods and the validation of the results.
