Research on the Robotic Polishing Combined with Electromagnetic Field of Rapid Metal Tool
In the rapid metal tooling, high efficient polishing process can improve the mould quality and shorten the lead time of the rapid tool, but the polishing process is frequently carried out manually. The application of industrial robot for the polishing process can minimize the production times and improve the working environment on a certain extent. In order to improve the robotic polishing efficiency continuously, the robotic polishing process combined with electromagnetic field is developed to fit for the application of commercial industrial robot, which is hard to be controlled online for its close control system. Free abrasive and soft polishing tool are also applied in the robotic polishing process to cooperate with the electromagnetic field. A minitype electromagnet is trial-manufactured and connected to the robotic end-effector, which can act on the polished surface along with the robotic moving. The electromagnet is coiled as solenoid that the polishing tool and the electrical spindle can be fixed in the hollow. A partition & flexible mapping method based on CAM is developed to generate the uniform robotic polishing path, which can compensate the elastic deformation and the abrasion of the soft polishing tool. Experiments are executed to test the infference between the electromagnetic field intensity and the polishing efficiency. The result shows that the polished material removal can increase over 50％ when the ferromagnetic substrate is acted by the electromagnetic field about 170 Gs.
