【正文】 ystem software, the software is designed with modular method. Based on the control system function, different modules are designed for multitask ability of control system. The main control module should acplish many plex tasks, such as the initialization, the NC program input, edit piling, setting parameters and operation. So it is needed to design a series of unattached function program modules, and furthermore, the same program module has the different module contents under the different control methods. 大連交通大學(xué) 2020 屆本科畢業(yè)生畢業(yè)設(shè)計（論文）外文翻譯 j i The control program is designed based on the Windows operating system, so it has the multitask coordinated ability. In the program, user manipulative performance is posed of many windows and each of them executes one task. And the functions are realized petitively in the different windows. The states of each task are managed by the management program [5][6]. The main function of mainmenu performance is monitoring, performance management, function controlling and system managing. The control part is the vital part of the whole software, and it determines the qualification of the control system. The flow chat of the whole software is shown in . After initialization of the system, the reference point setting and etc., the SERCOS Master’s drivers can be used for operating its interface card. And SERCOSMaster interface card supplies the difference interpolation functions which are available for movement control. 5 Measurement Positioning accuracy of the machine tool six axes are measured by ML10 laser interferometer made by the Renishaw Company. The measurement results are analyzed by the corresponding analysis software. The following results are obtained. Overall Accuracy, A = Max (x? x). Positive Repeatability Accuracy, pos rep=max posmin pos. Reverse Repeatability Accuracy, rev rep=max revmin rev Bidirectional Repeatability Accuracy B= x ↑ ?x ↓ The analysis results are shown in table 1. The max overall accuracy is , the max positive repeatability is , the max reverse repeatability is , and the bidirectional repeatability is . From the results it is found that the control system can satisfy the machine tool’ s accuracy request. Table 1. Positioning accuracy of six axes motion axes Overall Accuracy(?m) Positive Repeatability (?m) Reverse Repeatability (?m) Bidirectional Repeatability (?m) X axis Y axis Z axis U axis V axis 264 W axis 6 Conclusions 1. Based on the CH2020, the control system of the lathing and welding 大連交通大學(xué) 2020 屆本科畢業(yè)生畢業(yè)設(shè)計（論文）外文翻譯 pound NC machine tool is designed, which
