Synthesis of Motor Motion Curves for Intermittent Indexing Tables with Minimized Positioning Time

A procedure that can be used to synthesize motor motion curves with minimized positioning time for intermittent indexing tables at high speeds is presented. First, based on the measured dynamic characteristic of an indexing table, it is then simulated as a two-degree-of-freedom (two-DOF) system to derive the equations of motion. Subsequently, favorable parameters for defining asymmetrical motor motion commands by s-curves for the modeled indexing table with improved kinematic and dynamic performance are identified. To verify the accuracy and effectiveness of the proposed approach, numerical and experimental results are revealed and compared to those obtained by using the traditional method
