Entwicklung einer Projektierungstheorie fuer die Mehrwerkzeugbearbeitung mit den Moeglichkeiten der modernen CNC-Werkzeugmaschinen

摘要

The configuration of multi-tool machining on the CNC machine tools is essentially based on the intuition of the setter. Planners often avoid such complicated facilities, which means that the technological potential of modern CNC machine tools is not exhausted. Therefore, the main condition for solving the problem described is the development of a project planning theory for multi-tool machining, taking into account the possibilities of modern CNC machine tools. It is therefore necessary to have a model for determining the machining errors in multi-tool machines, taking into account the spatial arrangement of the tools, taking into account the simultaneous effect of all forces involved from all tools of the machine and the elastic displacements of the technological system in all coordinate directions. For this reason, a uniform model that records the nomenclature of multi-tool machines is offered for the dimensional deviations. A class of multi-tool machines which allow an analytical representation of the model is selected for the scatter fields. A uniform algorithm was developed to calculate the scattering fields of the dimensional deviations according to an analytical model. It shows the procedure for controlling multi-tool processes based on the developed theory of accuracy, including the optimization of the structure of multi-tool machining and the calculation of the maximum permissible cutting values.
