To provide point-to-point output motions needed for automation, intermittent indexing tables have widely been employed in various industries. For ensuring adequate production volume and profit margins, such devices are usually required to accurately generate intermittent motions as rapidly as possible. As a result, both of the positioning time and residual vibration are major concerns with the design of a fast, intermittent indexing table.
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 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.
