On June 16, at the invitation of Professor Wu Zhigang and Chen Rong of the State Key Laboratory of Digital Manufacturing Equipment and Technology,Robert G. Landers who is a Professor of Mechanical Engineering and the Associate Chair for Graduate Affairs in the Department of Mechanical and Aerospace Engineering at the Missouri University of Science and Technology made the academic report titled “Machine Tool and Robot Volumetric Error Compensation”in the room A416 of the Advanced Manufacturing Region.
At the meeting, Professor Robert G. Landers briefly introduced the basic situation of Missouri University of Science and Technology above all. Then combing with his recent progress, Professor Robert G. Landers gave a detailed account of the error compensation of large machine tools and industrial robots. A laser tracker is used to measure the machine tool or robot geometric errors, and the Implicit Loop Method, which is based on a maximum likelihood estimator, is employed to identify the coefficients of the geometric error model. An optimization algorithm is used to populate compensation tables for machine tools, or the inverse Jacobian method is used to modify the joint commands for robots.After the report, he discussed related issues with the present teachers and students in depth.
