Abstract
|
Ultra-precision machining has become the key to success in international competition , which is based on high-precision targeting technology in integrated application of new technologies , excellence in all aspects , be possible to break through the conventional techniques of not to the accuracy of the boundaries , and reach a new high - precision indicators . Grinding as an important processing methods in the ultra-precision machining , growing attention. Access to the technical information of the plane grinding at home and abroad on the basis of the plane CNC grinding machine the following studies : (1) the establishment of a workpiece friction rotation of the double-sided grinding CNC surface grinding machine model of the grinding disc to the workpiece friction drive torque , and analyzes the relative motion between the spinning motion of the workpiece and the workpiece and the grinding disc , laid a theoretical foundation for the future design of machine tool , grinding parameter selection and optimization . (2) Design on the workpiece friction rotation of the double - sided grinding CNC surface grinding machine , under the grinding bodies and bearing structure static analysis using the finite element method . (3 ) the machine with a dual-frequency laser interferometer detection of motion accuracy straightness Linear error compensation and based on the results of the machine . (4) the use of NUM system provides the rich the PLC resources as well as dynamic operation function, the force and position control for a preliminary study .
