"多模式CAD信息智能提取算法培训及实践"

is paper will discuss the support for multiple mode CAD information intelligent extraction algorithm. Based on DPM technology, it further proposes the model of constructing CAD/CAM/CAPP integrated system. The main topics to be discussed include the definition of CAD templates, information extraction algorithms, CAD data and PDM data exchange, as well as the model and implementation of integrated systems. The extraction of process information from CAD graphics is essential for the optimization of production processes. This article will address the shortcomings of current systems and propose a more comprehensive and intelligent approach to extracting information from CAD graphics. By using DPM technology as a foundation, the integration of CAD/CAM/CAPP systems will be explored, highlighting the benefits of a multi-mode CAD information extraction algorithm. Key words: information extraction, PDM, CAD/CAM/CAPP, integrated system. Overall, the paper aims to provide a comprehensive training on the methods of extracting process information from CAD graphics. It will cover a range of topics, from the definition of CAD templates to the implementation of integrated systems. The goal is to equip the readers with the necessary knowledge and skills to effectively extract process information from CAD graphics, ultimately improving the efficiency and productivity of production units.
