Interactions between mechanical vibrations and surface roughness during the micro milling process
Abstract
Nowadays micro structured parts in sufficient quality concerning surface roughness and accuracy are only achievable by extensive effort. Especially the requirements, concerning the process results, on mechanical micro cutting technologies are very high. This paper gives an overview of the investigations in the for-front of an application-oriented, closed loop prediction model. In this context experimental series were carried out on a high precision milling machine tool. In addition to the measurements of the surface quality, accelerations caused by vibrations during the machining process were acquired at the spindle housing. Correlations between the process parameters and the surface roughness as well as the vibrations excited during the milling process and the surface quality were evaluated and presented in this paper. Correlations between the roughness at surfaces of high and low quality and the auto spectra of accelerations are visible. That means that the data acquisition by using this analysis can be implemented for further investigation.
