Abstract
The study presents a new method for 5-axis machining of blisk, which consists of both
roughing tunnels and finishing blades. The ruled surface is used to approximate the freeform
surface of blade, and the boundary contour of the tunnel is then determined. Based on the double
point offset method, the 5-axis tool paths for roughing blisk tunnel region are generated. Similarly,
by linking the corresponding points on the tool center curves and the tool axis drive curves, the
spiral tool paths are developed to finish milling thin-walled blades taking into account the residual
stresses induced part distortion during machining. This strategy is experimentally verified.
