The positioning operation of axes is essential before initiating machining operations in NC machine tools. Residual vibration following the positioning operations of the axes deteriorates the cycle time and quality of the machined parts. The purpose of this study is to establish a design method for positioning commands that reduces the residual vibration generated after positioning. Because a shorter distance positioning of several millimeters with triangular acceleration profiles is typically applied before machining, the residual vibration amplitude is formulated as a superposition of responses to step jerk inputs. By analyzing an equation that predicts the residual vibration generated by the positioning operations, the condition of the command that reduces the residual vibration is derived, and an algorithm that uniquely designs the positioning command is proposed. It is experimentally confirmed that the positioning commands designed using the proposed method can reduce residual vibrations.
