金属切削加工时,在保证零件规定的加工质量前提下,如何提高劳动生产率、降低零件的加工成本以及提高其经济效益,都是人们非常关心的问题。为了实现这些目标,在生产实践中,当机床设备、切削刀具和加工对象等初步明确后,就应对金属切削参数,其中主要对切削用量(V、a_p、f)进行优化设计,以寻求最佳的切削用量及有关最佳参数。随着电子计算机的日益广泛使用,在机械制造领域内的计算机辅助设计和计算机辅助制造(CAD和CAM)正在我国逐步兴起。例如过去我们搞过的《组合机床多轴箱的CAD》,其中就遇到必须解决切削用量的选取问题,最终希望建立切削用量数据库;就是范围较小的计算机辅助工艺设计(CAPP),也至少希望建立切削用量的数据文件,这样才能使工作有效地进行。何况切削用量对刀具的合理使用、机床的合理
Metal cutting, the premise of ensuring the quality of parts under the processing, how to improve labor productivity, reduce parts processing costs and improve their economic efficiency, are people are very concerned about the issue. In order to achieve these goals, in the production practice, when the machine tools, cutting tools and machining objects are initially defined, metal cutting parameters should be dealt with. The cutting parameters (V, a_p, f) are optimized to find the best The amount of cutting and the best parameters. With the increasingly widespread use of electronic computers, computer-aided design and computer-aided manufacturing (CAD and CAM) in the field of mechanical manufacturing are gradually emerging in our country. For example, in the past we have engaged in the “combination of machine toolbox multi-axis box CAD,” which encountered the need to solve the selection of cutting the amount of material, and ultimately want to create a database of cutting; is a relatively small range of computer-aided process design (CAPP) It is hoped that a data file of cutting costs will be established so that work can be carried out efficiently. Not to mention the amount of cutting tools on the rational use of the machine tool is reasonable
