Abstract As the machining operation of closed blisk in 5-axis machine tool is a highly comprehensive process, the blade adjoining error is influenced by many factors such as machine tool, fixture, workpiece, clamping process, cutting parameters, workers and so on. Based on analyzing the formation mechanism of blade adjoining error, this paper presents a machining process flow for closed blisk and proposes a high-accuracy positioning method of workpiece as well as a quick calibration procedure of machine tool zero point by using machine tool probe. The verification experiment demonstrates that the presented strategy could control the blade adjoining error in machining operation of closed blisk effectively.
