作者根据第34届CIRP年会情况综述了当前机械制造的总趋势是自动化、精密化和难加工材料的应用。反映在金属切削研究的主导思想仍然是科研必须结合工业需要。切削过程机理的研究、计算机的大量应用和应用优化理论、统计数学进行优化设计,是研究中的三个重要特征。 Based on the 34th Annual CIRP Annual Meeting, the authors summarize the current trend in machine construction for the automation, precision and difficult-to-use materials. The dominant thinking reflected in the study of metal cutting remains that research must be combined with industrial needs. Research on the mechanism of cutting process, a large number of computer applications and application optimization theory, statistical mathematics to optimize the design is the study of the three important features.
