The Study on Mechanical Modeling and Controlling System of Simulating Milling Force Mechanism

Abstract:

To design a set of force-applying mechanism, simulate the stresses of workbench in vertical milling process and complete dynamic test of performance parameters by controlling the mechanism on the basis of the research of a testing stand of precision preserve of rolling functional components. This paper establishes a mechanical model to simulate the milling stresses of workbench, and makes use of the principle of the force and moment equal to deduce the functional relationships between the force of mechanism applying and the milling force, makes appropriate transformation according to the working principle of force-applying mechanism; adopt the “PC+NC” NC system architecture and use VB complete programming of the testing stand open NC system based on the multiple axis controller PMAC. Operators can achieve the function of testing stand by the established system interface. In the process of the test of performance parameters by testing stand, the force-applying mechanism applies milling force which could ensure test data accuracy and also save energy.
