Double-turntable five-axis numerical control machine tool virtual assembling and numerical control machining simulation method

The invention discloses a double-turntable five-axis numerical control machine tool virtual assembling and numerical control machining simulation method and provides a simulation method capable of improving simulation efficiency under the premise of guaranteeing simulation correctness. The method includes: modeling; conducting three-dimensional modeling of blanks and clamps required in all moving components, a machine tool body and numerical control machining; connecting all moving components and the machine tool body to conduct virtual assembling according to a moving relation by using a Pro/E three-dimensional platform; operating a virtual simulating machine tool; outputting models of all components in a standard template library (STL) form on the basis of the same coordinate system; establishing a double-turntable five-axis numerical control machine tool virtual model; establishing a model tree in VERICUT, and the sequence of model components includes two branches: machine tool body Base - Y axis - X axis - A axis - C axis - clamp - blank and machine tool body Base - Z axis - main axis - tool; the STL assembly model output by Pro/E is led into corresponding components in VERICUT directly, namely the double-turntable five-axis numerical control machine tool virtual model is established; and numerical control machining simulation is operated.
