The purpose of this study is to clarify the relationship between the dynamic motion error of feed drive systems and the finished surface. In order to achieve this purpose, finished surface simulation of cone frustum which is used by evaluating machining accuracy of 5-axis controlled machine tool is proposed. In this study, motion trajectory of tool tip and tool orientation by considering dynamic characteristic are simulated by model of feed drive systems of 5-axis controlled machine tool. Then finished surface of cone frustum is simulated by using these results. In addition, in order to clarify the valid of simulation result and influence of motion error of axes on finished surface, cutting test is carried out. As the results, the influence of motion error of each axis on finished surface is discussed based on the results of cutting tests and simulations
