【 摘 要 】

Problem statement: Machines dynamic performance depends not only upon themechanical structure and components but also the drives and control system. However, the design ofthe machines is still at the nascent stage by working on an individual machine basis, hence lacksgeneric scientific approach and design guideline. Approach: Using computer models integrated drivesand control system to predict the dynamic performance of ultra-precision machine tools can helpmanufacturers substantially reduce the lead time and cost of developing new machine. This studyproposed a holistic integrated dynamic design and modeling approach, which supports analysis andoptimization of the overall machine dynamic performance at the early design stage. The modeling andsimulation process on an ultra-precision lathe machine tool is presented using the proposed approach.Results: Model of an ultra precision machine tool is established and used to predict the overallmachine performance of the configuration. Deformations of base and fixed sideways in motion arecalculated to demonstrate the valid of the method. Conclusion: Excellent accuracy on motiondeformation is achieved. The designed and implemented integrated time-domain dynamic analysis andmodeling system can predict the static and dynamic performance of ultra-precision machine tools,which can reduce the lead time and the cost of developing new machine.
