| Abstract: | Taking the boring system of TX1600 boring-milling machining center as the research object, in view of deformation problem caused by heat load and structural load, the thermal-structure coupling model for the boring system was established to analyze the deformation when the ram in different strokes. The rule of deformation of the boring system varied with the stroke of ram was known. A cost-effective error compensation mechanism is proposed, which can improve the machining precision of machine tools greatly. |
