Develop Of NC System And Mechanism Simulation For 3-DOF Parallel Experiment Flat

Multi-degree-of-freedom parallel architecture has such disadvantages as difficult modeling, kinematics coupling, and furthermore a lot of customers needn't six-degree-of-freedom machine tool. Therefore some less-degree-of-freedom parallel architecture which has advantages as simple mechanism and lower cost has been a new study field and has obvious market potential.A 3-HSS parallel manipulator is proposed in this paper. It's easy to build the move modeling and get the direct and inverse kinematics for this machine tool. This machine tool also has other advantages, such as spacious workspace in horizon direction, simple structure, easy controlling and so on. The kinematics analysis and the kinematics simulation of this parallel mechanism have been studied. Regard Windows as the operating platform, the open NC system for parallel machine tool is set up. So the mainly content is as following:According to characteristic of parallel mechanism, the mathematical model of the 3-HSS parallel manipulator has been set up. And the inverse position kinematics and the DOF of the 3-HSS parallel mechanism are analyzed.The soft ware of NC systems is designed and developed according to the soft project thought and target -oriented design method. Windows XP is regarded as the operating platform, and Visual C ++ is regarded as the programming environment, module programming technology is adopted to design the user interface and some universal modules include the decipher module, the human-computer interaction module, interpolation module, cutter compensation module, the tool track simulation module and so on.The 3-HSS Parallel mechanism has been modeled based on UG, and the simulation and analyses on the parallel mechanism is done using ADAMS; the research on the machining trace of the 3-DOF parallel experiment flat has been done in the environment of ADAMS, and the correct machining trace is get.
