Abstract
With the rapid development of modern industrial technology, complex curved parts are widely used in aerospace, automobile manufacturing, mold design and other fields. However, high-precision machining of complex surfaces has always been a challenge for the manufacturing industry. The integration of CAD/CAM (computer aided design and computer aided manufacturing) technology provides a strong technical support for complex surface processing, which greatly promotes the improvement of processing efficiency and accuracy. Based on CAD/CAM technology, this paper discusses the optimization strategy of complex surface machining deeply, aiming at providing theoretical basis and practical guidance for improving the machining quality of complex surface parts. The characteristics and difficulties of complex surface machining are analyzed in this paper. Complex curved parts have the characteristics of complex shape, high precision and diverse materials, which requires that many factors such as tool path planning, cutting parameter selection and machining stability control must be fully considered in the machining process. CAD/CAM technology provides the possibility for precise machining of complex surface by means of digital modeling, automatic programming and simulation. In this paper, the optimization method of complex surface machining based on CAD/CAM technology is described in detail. In the CAD stage, the three-dimensional model of complex surface is constructed by high-precision modeling technology to ensure the accuracy of design data. In the CAM stage, advanced algorithms are used for tool path planning and cutting parameter optimization to reduce vibration and deformation during machining and improve machining accuracy and surface quality. At the same time, physical parameters such as cutting force and temperature field are predicted by simulation technology to provide scientific basis for the adjustment of machining parameters. This paper summarizes the application effect of complex surface machining optimization based on CAD/CAM technology. By optimizing the machining strategy, not only the machining precision and surface quality of complex curved parts are significantly improved, but also the processing cycle is shortened and the production cost is reduced. In addition, the wide application of CAD/CAM technology has also promoted the digital transformation and intelligent upgrading of the manufacturing industry, and injected new impetus into the sustainable development of the manufacturing industry.
