[Abstract]:With the rapid development of modern science and technology, machining and manufacturing technology is constantly improving. How to achieve high-precision machining has become the most important part of China's machinery manufacturing industry. This paper takes part in the 863 project of the "12th Five-Year Plan", and studies the error modeling, error analysis and error compensation of the complex boring and milling machining center which takes the complicated box parts as the machining object. The spatial error model of precision compound boring and milling machining center is established, its error is measured, analyzed and compensated, and an error analysis system is developed to improve the machining accuracy of compound boring and milling machining center. Effectively improve the quality of the end product. This paper mainly focuses on the following four aspects: research on the structure and error analysis of the overall layout of the compound boring and milling machining center, considering the structure and precision requirements of the military complex box parts, and combining with the structural characteristics of the new NC machine tool, The main error sources affecting machining accuracy, such as guide rail error, table slide error, spindle rotation error of machine tool, bending error of milling beam and bending error of boring and sliding pillow, are analyzed, and the definition of comprehensive error is introduced. In order to establish the mathematical model, the synthetic spatial error model of the compound boring and milling machining center is established. The topological structure of the special compound boring and milling machining center and the low sequence body array are established by the modeling method of the multi-body system. The Cartesian coordinate system of each typical body is defined, and the eigenmatrix equation is established. Finally, the model of spatial error of vertical milling and the model of spatial error of horizontal boring and milling are established respectively. The typical error analysis of the key parts of the machining center of compound boring and milling is carried out according to the analysis and research of the typical errors of the key parts. Laser interferometer is used to measure three kinds of errors, which are the error of NC turntable moving along X axis, the error of milling slider moving along Y2 axis, and the error of boring slider moving along Y3 axis. The error compensation and Comprehensive error Analysis Interface of compound boring and Milling Machining Center is obtained by using nine-line method. The error analysis of vertical milling of Z2-axis beam and horizontal boring of Z3-axis sliding pillow is carried out. It is known that the error value varies with the stroke, and a single measurement error and pre-compensation can not improve the machining accuracy. Therefore, the finite element analysis is used to obtain the functional relationship between the error and the stroke. According to the real-time compensation of the travel position and the spatial error model, the error analysis interface of compound boring and milling machining center is developed.
