Vibrations of a tool or a workpiece in cutting shorten tool life and deteriorate a surface roughness. In this research, we propose a method to reduce vibrations of the workpiece at a cutting point. An algorithm that generates a cutting path to minimize workpiece displacements at a cutting point is developed. The algorithm is applied to the generation of end milling paths for a cantilever part. A simulative investigation shows that obtained cutting paths can suppress the workpiece displacement compared with two conventional cutting paths.
