To solve the problem of datum failure caused by deformation of workpieces during mirror milling, a kinematic model of wall thicknesses for mirror milling based on screw theory was established. Considering comprehensively of parts machining requirements and mirror milling constraints, a“ support–milling” trajectory generation method was proposed. Meanwhile, a supporting trajectory adjustment model for deformation compensation was developed. Then automatic trimming of the“ support–milling” trajectory for mirror milling was realized. The results of the verification experiments on the grid mirror milling of thin-walled parts show that the “support–milling” trajectory generation and automatic adjustment method for mirror milling can meet the requirements of the wall thickness for mirror milling.
