This paper presents a new method of computing constant scallop height tool paths in 5-axis milling. Indeed, usual iso-scallop tool path computation methods in 3-axis or 5-axis milling generate tool path selfintersections, which prevent from reaching the required quality and productivity. The proposed approach consists in following parallel planes in 5-axis milling to avoid self-intersection of the tool path. The constant scallop height is guaranteed by modifying the machined strip width by means of the orientation angles of tool axis (yaw and tilt angles). Resulting scallop height and surface roughness are simulated using the NBuffer method.
