The invention discloses a high-speed and high-precision processing method of a double motion platform, comprising: connecting a UV motion platform in series on a machine tool equipped with an XY motion platform to form a double motion platform structure; The data is processed, and the displacement interpolation point sequence of the XY motion platform and the displacement interpolation point sequence of the UV motion platform are output to control the synchronous movement of the two motion platforms and realize high-speed and high-precision processing; the algorithm proposed by the invention can coordinate the two platforms The synchronous motion of the two platforms completes the reasonable motion distribution of the two platforms, so that the large-stroke XY motion platform can move at high speed, so that the high-speed and high-acceleration UV motion platform can cooperate with the XY motion platform, and restore the high-precision trajectory through motion synthesis to achieve high speed. High-precision processing effectively overcomes the problem that the existing technology cannot achieve high speed and high precision at the same time.
Description
A high-speed and high-precision machining method for a dual-motion platform technical field The present invention relates to the motion algorithm technical field of dual motion platform, be specifically related to a kind of dual motion platform equipped with UV motion platform The high-speed and high-precision machining method of the motion platform can be applied to various types of machine tools equipped with an XY motion platform, such as plane cutting machines bed etc. Background technique Common plane cutting machine tools such as laser cutting machine or leather cutting machine on the market at present, mostly use XY motion plane [0002] The stage realizes plane movement and has a large stroke, but the inertia is large, the acceleration performance is general, and the speed-up is slow. When the XY motion stage executes At the corner between the trajectories, because of the sudden change of direction at the corner, in order to ensure the accuracy of the movement...
