Abstract


This article focused on the rapid spread and development needs of the current CNC technology, how to improve the existing CNC machine tools, machining accuracy and product quality, and improve the overall level of manufacturing and to give better play to the advantages of CNC machine tools in-depth discussions, CNC lathe finishing program decoding method to conduct in-depth research; processing center error compensation technology, especially in the error compensation technology research, through theoretical analysis, error modeling, machine tools, precision testing, error analysis and error compensation experiments. System to improve all aspects of compensation, especially in the practical application to explore a more feasible method. The main tasks are as follows: 1. Research and analysis of a typical system at home and abroad. From the application of the numerical control system, the functional structure and characteristics, research and analysis in the current market, the largest CNC machine tools share three CNC system FANUC CNC system, SIEMENS CNC system and Huazhong CNC system, typical NC system. The NC system with independent intellectual property rights TDNC-L4 architecture design concept. 2. The CNC lathe finishing procedures decoding method. Research CNC lathe the finishing procedures decoding module realization method, the traditional decoding method based on a combination of compilation and interpretation decoding method to take the task of error detection and decoding scan way of finishing the program twice The task of separation. Error detection task to take a scan layer by layer, to ensure full and quick check of a procedural error; taking into account the subsequent decoding tasks using interpretation, the real-time requirements, adding the finishing of the part program error detection task stored in accordance with the prescribed format and stored in the designated storage area, in order to improve the the subsequent decoding speed of execution and can save memory unit. 3 build error compensation model, the use of the laser interferometer advanced testing equipment machine error measurement, to achieve real-time machine error compensation. CNC machine tools geometry (positioning) error detection and compensation technique, a more systematic and in-depth discussion on the CNC machine work space plane (2D) error detection, modeling and compensation techniques, the use of a laser interferometer detection establish a geometric error model of the laser interferometer-based three-axis CNC machining centers. On the basis of accurate knowledge of the three-axis CNC machining centers geometric error, the error compensation software error compensation. The study using the laser interferometer detects the CNC machine tool position error, and then through the system parameters of the CNC machine tool to compensate for. Practice shows that, after error compensation, CNC machining accuracy can be improved significantly. Can be widely used in engineering practice.
