Due to the problem of the mutual interaction between the polishing tool system and the control of poses and positions, it is difficult to hybrid-synchronizationally control the polishing force, the posture of polishing tool head and the polishing trajectory. So the article designed a set of compliant tools that take the pneumatic servo system as the control system, which was used for active polishing aspheric surface of Robot. It was to accomplish the Robots self-adaptive control to the posture of the polishing tool as well as to figure out the correlation of the contact deformation between the polishing tool and the work piece surface, which makes a theoretical analysis on dynamic and steady characteristics of the contact deformation of the tool system. It applied the meek and polishing tools to the polishing processing of the rough machining of large aspheric surface samples to obtain the data. According to the statistics, the polishing tools can effectively solve the problem of the mutual interaction between the polishing tool system and the control of poses and positions. It also owns good adaptive ability and its machining aspheric surface quality can achieve nanoscale.
First it sets up a kinematical model for a kind of industrial robots by D-H notation, and inverse kinematics solutions of its end effector are deduced according to its motion trail. By transforming the rotation angles of the robot’s joints into impulse signals, pulse signals could be used to interpolate its motion trail. Finally, it uses Matlab software to join various curve of each joint impulse signal, and formulation a mathematical model about various curve of each joint impulse signal. In this way, it could simplify program in INFORM Ⅲ language. Simulation shows that direct pulse signal interpolation improves the accuracy of trajectory positioning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
