Paper Title:
Research on Machine Tool Components Contribution Calculation and the Weak Link Identification of the Whole Machine
  Abstract

After modeling and calculating of whole machine, the static and dynamic characteristics are obtained, since it is difficult not only to judge out machine components’ influence on machining precision intuitively , but also to identify the weak link of the whole machine. Therefore, through extracting key nodes coordinates of machine components and deformation information of finite element software calculated, we brought forward a space vector transfer algorithm, calculated the contribution of components for tools and work piece system and expressed impact of machine components on tool and work piece system by histogram. By this means ,we can judge out the whole machine’s weak links intuitively. Take XK713B Vertical Milling Machine as the case research object, extract key nodes and their deformation information of general structure such as lathe bed , column, headstock, sliding table, workbench etc. By using space vector transfer algorithm, the result shows that the largest contribution to tool system and workbench system is column, which is the weakest link in the whole machine and its vibration type is swing. According to this, further optimize design of column can be proceed.
