This study aims to improve the efficiency of free-form surface machining using a five-axis controlled machine tool and a barrel tool. The barrel tool has cutting edges with curvatures smaller than its radius; thus, its pick feed width is larger than that of a conventional ball end mill with the same tool radius. Therefore, the machining efficiency can be improved. Barrel tools can be effectively utilized in a five-axis controlled machine tool. When five-axis controlled machining, tool interference may occur, which should be avoided during actual machine operation. Additionally, a sudden change in tool posture adversely affects the quality of the machined surface. This paper proposes a method to obtain the cutting points that render cusp heights below the target value. A method for generating an interference-free tool path, in which the tool posture changes continuously, is also proposed. The usefulness of the developed methods was confirmed through machining simulations.
