Апстракт:
During the machining of complex shape workpieces with asymmetrical surfaces, the accuracy of measures is often conditioned by the compliance of fixture for positioning and clamping the workpiece. This paper deals with the problem of clamping fixtures compliance during the machining of complex geometry workpiece on the 5-axial milling machine tool. Accuracy measures and quality of processed surfaces depend, to a large extent, on the compliance of fixture for positioning and clamping the workpiece and the stiffness of the machine tool system. In this paper, the methodology of analysis of fixtures from the aspect of compliance and results of measurement and calculation of displacement and vibrations of the workpiece during the machining process, is going to be presented. On the basis of analysis and measurement results, zones, elements and fixture sub-assemblies of relatively large compliance are determined. In order to reduce compliance, that is, to increase the stiffness of fixtures and raise the level of stability processes, it is presented the proposal of measures that tool reconstruction should include.
