Manufacturing Execution System (MES) is one of the crucial technologies that realizing the information integration for the enterprise, and its function modeling is the base of MES design and implementation. Basis on the analysis of the business process in mechanical blanking workshop and the functional requirements of MES system, the IDEF0 method was adopted to construct the function model of MES system oriented to mechanical blanking workshop, and a detailed description of the function modules and their relationship was given, which laid the foundation for the software development of the MES system.

The finite element method was applied in the construction design of the welding column of CNC boring machine for dynamic analysis and modal analysis. The laws of deformation and stress of a loaded column were obtained, and the natural frequency of each step and modes of column were also given according to this method. The results implied that the strength and the stiffness of welding column were met the machining requirements. Machine working frequency far less than inherent frequency, thus resonance is not easy to occur. Through the way, the optimization proposals of structure were given.
