The Research And Developing Of Bending Machine Numerical Control System Based On Database

As CNC bending machine used for bending sheet metal, it is a kind of special-used automation machinery equipment. Due to its Simple operability and Process versatility, which is widely used in the industry. With the industrial development of China, high efficiency, high precision and intelligent will be the trend of Traditional industries.The Springback is a common phenomenon in the sheet metal processing. It is the key issues affecting the bending machine’s precision, and the phenomenon is one of the major flaws existing in the bent V-shaped sheet metal. The material properties, the sheet’s initial shape, mold geometry and process conditions will make the flaws and the accuracy of CNC bending machine is still difficult to meet the requirements of industrial applications. The traditional solution to obtain sufficient forming precision is the repeated testing and correction.To optimize CNC bending machine system’s parameter settings to ensure the accuracy of the premise and less bending correction steps is the main content of this paper. It will be efficiency and improved the reliability in data migration.In this paper, an appropriate description of CNC bending machine and investigation of the sheet metal springback phenomenon had been made. Trying to exploit a database management software to solve this problem. Developed a database system in CNC bending machine to achieve the parameter’s optimization. By Human-machine interaction and recording of bending parameter data storage, it achieved the modular management of bending parameter and Solve the repeated Correction problem. According to the parameters of different function and attribute design data table, the related parameters of CNC system are classified according to different parameters. Add the appropriate insert, delete and other functions, ensuring the accuracy of the query and query efficiency, and ultimately achieve efficient and high precision bending process.
