Abstract： A machining strategy for variable layer thickness with layered surfaces was proposed to address the rough machining issues of the channels across the entire blisk components. Considering the characteristics of the variation in the width of the channels across the entire blisk components，the geodesic ofset was used to determine the toolpath boundaries on both sides of the channels，and the step size and the number of paths were determined. A planning method for the longitudinal milling path along the channels was proposed，and then the tool axis vector of the channel boundaries is calculated，and the tool axis vector of the middle cutter positions of the channel boundaries is calculated by quaternion interpolation. The calculation results show that，compared with the conventional uniform layering method using the blisk hub rotary surface offset or the blisk covering rotary surface offset， the variable layer thickness surface delamination may better adapt to the surface changes from the covered rotary surface to the hub rotary surface，the surface quality of the blades is ensured，with the advantage of a uniform machined blade surface allowance，and the feasibility of the algorithm was verified through machining examples.
