With the development of society, automation is the trends of industry in the future. The manufacturing industry is also facing great challenges in our country. Various enterprises in order to compensate for the low rate of CNC machine tools, the status of the transformation of the old CNC machine tools has become a trend. So far, Transformation of the old machine at home and abroad on the early stage of assessment is still not mature unified approach, and most of the transformation on the basis of simply experience and efficiency of the original machine have been carried out with the corresponding numerical control system. As for the transformation of the original machine tools, enhance the performance of work done to extend the capabilities of the relatively small.The purpose of this research thesis is to transform pre-assessment for the machine tool by some of the theory of machine tool reliability analysis methods. With the finite element method, and relying on large-scale three-dimensional design software Pro/E, general-purpose finite element analysis software ANSYS, to carry out joint analysis for the model in this paper. Modal analysis conclusions, it is used in the choice and design of drive systems of machine tool.In the modeling process. Because pre-processing module of the ANSYS software to complex three-dimensional modeling approach is not easy maneuverability, and such a complex structure modeling can not be completed as accurately and efficiently coordinate boring machine in this paper, so in the modeling approach, using the powerful 3D modeling design software Pro/ENGINEER Wildfire2.0 to do three-dimensional solid model, then transmit the model into ANSYS10.0 by a seamless interface. Improve the modeling efficiency, and ensure the quality of the model. In order to the calculation precision and calculation of the size of a reasonable physical model to make a certain simplified. Under the premise of the analysis of cell quantity, quality and layout, to build a finite element model of machine tool of the whole body with the solid element mesh.Machine tool is equipped with high speed drive systems, it is based on modal analysis, while reference to experience in design and calculation. functional expansion of the machine tool has carried out with taking into account the machine tool itself, better stability and machining accuracy of the original machine, so the original can only be used in precision drilling mold, mold and other functions of the coordinates of boring machine, also has milling capabilities, while achieving more axis of machine tools, thereby matching a powerful CNC system and servo drive systems. So that the machine can be transformed to adapt to a wider range of processing requirements, improve resource utilization.
