Class Objectives
/Class Outline This lecture teaches fundamental and practical knowledge to design a positioning mechatronics system, where the accuracy of motion is essential. Students will have basic and practical knowledge on mechanical elements in a positioning system, such as a servo motor, a ball screw, a linear motor, a guideway, and an encoder. Its principle, as well as causes for error motions, is studied. Measurement instruments and methodologies for error motions of a positioning system is lectured.
For a multi-axis positioning system, new measurement methodologies based on the machine's kinematic model is lectured. The theory to derive the machine kinematic model based on the coordinate transformation, model-based measurement schemes, error cause diagnosis, and numerical compensation are studied. This lecture mainly considers a positioning system in a machine tool.
