The tool path trajectory generation for CNC machining has been a main topic in the improvement of the manufacturing process for many years. Different approaches tried to merge efficiency and minimal tool wear with reasonable computing times. A smooth curvature progression of the tool path is a main requirement to limit jerks in all axes and thus ensure minimal tool wear. Currently this requirement is met by constructing tool paths with polynomials or smoothing simpler linear and circular curves. This paper presents an alternative interpolation method based on curvature-smooth clothoids.
