Measuring And Controling System Develops On Gear Measuring Center

The level of domestic manufacturing is improving and developing continuously, and the foreign economy trade relationships is enhancing, so not only the requirements of gear machining and measuring are more and more strict, but also various error evaluation standards are deduced. The traditional gear measuring apparatus possessed high precision, but their single function and data process abilities couldn't meet the needs of automatic measuring mission. The thesis came from engineering fact, the target of building up a measuring and controlling system of gear measuring center was achieved successfully.The realization method of setting up a measuring and controlling system of gear measuring center was discussed, basing on electronic generative metrology and combining with coordinate measurement techniques to correct errors. The open CNC system, status inspection and control system, data collection system were established according to the mechanical characteristics. The hardware condition of automatic measuring cylindrical gear was founded by these means. The parameters and metrical techniques of gear works were abstracted and packed with the help of OOP thoughts, basing on the criterion of software engineering, the codes of measuring and controlling system were written, which was a part of user application software in gear measuring center. It includes data collection program, status inspection and control program, motion control and user interface program etc. Working together with the hardware, the functions of measuring errors in involutes cylindrical gear were accomplished.Develops on hardware and software of the measuring and controlling system had been experimented and indicated its success. The ability of automatic measuring involute cylindrical gear was acquired. The experience could be used into other developing or upgrading activities of the products with the same class.
