Apstrakt:
Dynamics characteristics of machine tools, especially modal parameters, have significant influence on the cutting process and cutting accuracy. This paper shows research of dynamic behaviour and determination of modal parameter of horizontal milling centres. For this purposes 3D CAD model of horizontal milling centre has been created using CATIA software, and modal analysis (natural frequencies and mode shapes of the machine tool structure) has been conducted by ANSYS Workbench and APDL. Results gained by FEM modal analysis are validate by experimental modal analysis. Modal parameters obtained experimentally and by FEM are compared, and results shows satisfactory matching.
