| Abstract: | A formation mechanism of machined work-piece surface and a modeling method of machining accura-cy prediction for CNC machine tools are studied based on the multi-body system theories. And a software sys-tem of machining accuracy pred;iction is developed for CNC machine tools based on virtual machining. Finally,a simulation of machining accuracy prediction is given to validate the proposed accuracy prediction systembased on the measuring and identifying of the synthesis errors which contain geometry errors, the heat deforma-tion errors and force deformation errors of a CNC machine tool. |
| Keywords: | machining accuracy prediction volumetric error multi-body system theory CNC machine tool |
