Modeling And Simulation Of Tilting Principal Axis Five-axis High-speed Milling Machine

Machine tool industry plays an important role in the development of industry in a country.However,there is still a great gap in the development of multi-axis machine between our country and developed nations.What is more, some developed nations regard high-end machine tools,especially five-axis machine tools,as strategic materials and limit their exportation to developing countries.Therefore,researching five-axis machine tools is very important to our country.First,the paper analyzes the structure of five-axis machine tools and studies the characteristics of all kinds of supporting structures.In accordance with the characteristics of large complex parts,such as large complex molds whose inertia is big and the parts are difficult to move,this paper raises a method to solve the question by moving and rotating the principal axis while keeping the part still.At the same time,the paper sets up the model of tilting principal axis five-axis high-speed milling machine.Furthermore,the key parts are selected and designed,such as the spindle system,rails and the feeding system.Second,the software UG is introduced.In addition,the text designs every part of the machine and has them installed by CAD part of UG.After that,the whole machine is simplified on the base of not impairing its normal operation. In this situation,the virtual model is more reasonable.Finally,the two directions swinging five-axis high-speed milling machine is transferred to ADAMS though Parasolid.Before simulating the machine, kinds of restrictions are programmed.The machine is proved correct by analyzing the data and simulated curves.The work in the paper provides a basis for the improvement of the machine and the further development,and lays foundation for CAM.
