GRAU, J., P. SOUČEK, and M. SULITKA. The Influence of Servo Drive Control on the NC Vertical Milling Machine Dynamic Compliance. Journal of Manufacturing and Materials Processing. 2020, 4(4), 1-18. ISSN 2504-4494. DOI 10.3390/jmmp4040111. Available from: https://www.mdpi.com/2504-4494/4/4/111
A model Numerical Control (NC) machine tool dynamic compliance is analyzed, including the influence of its mechanical structure and position control feed drive algorithms. The dynamic model of the machine tool is divided into two main parts, which are closest to the machining process. First, the milling head assembly group is presented as a system of one mass oscillating in a 2D plane and 3D space. Second, the motion axes assembly group, XY cross table with linear feed drive, is presented. A square 2 × 2 dimension matrix of the total dynamic compliance is evaluated within the feed drive control system included. Partial elements of the mechanical structure dynamic compliance matrix of the general N × N dimension are contained in the total dynamic compliance matrix.
