The purpose of this study is to provide a way to generate a tool path which considering the motion characteristics of feed drive systems. In order to achieve the purpose, this study focused onto the relationships between the motion characteristics of feed drive systems and machined surface. The relationships are investigated through both of actual cutting tests and its simulations. As the results of the investigations, it is clarified that the influence of the motion errors onto the machined surface depends on the tool path, even though the same motion errors exist.
