Abstract
The present invention discloses a post-processing method for a special seven-five axis linkage machine tool, comprising: building a multi-body kinematic model according to the structure of the machine tool, and building the multi-body kinematic model according to the sequence of workpiece-turntable-machine tool-cross beam-ram-milling head-cutting tool; establishing position coordinate transformation matrices according to the built multi-body kinematic model to obtain the matrices of cutter location points and tool orientation vectors; solving transformation equations of every motion axis of the machine tool and cutter location point coordinates according to the matrices of cutter location points and tool orientation vectors; building a corresponding relationship between the cutter location point coordinates and every motion axis of the machine tool based on a geometric level, and solving specific values of C-axis rotation angle of milling head and C2-axis rotation angle of the turntable.
