摘　　要：切削过程的稳定性直接影响到切削效率以及加工质量。鉴于稳定域仿真在切削过程中的重要作用,对基于稳定域仿真的切削数据库进行了研究。首先对切削数据库进行了需求分析,得出数据流图。然后在需求分析的基础上建立了切削数据库的概念模型,并将概念模型转化为关系模型。最后通过实例说明了切削数据库系统的工程应用方法。该数据库充分考虑到切削过程中的稳定性影响因素,并注重切削稳定性优化,能够为切削加工提供可靠的参数选取依据。he stability of cutting process affects the cutting efficiency and machining quality directly.Taking the vital function of the stability domain simulation into account,it researches the machining database based on stability domain simulation.Firstly,the demand analysis of the cutting database is put into practice and the data flow diagram is designed as the result of the analysis.Afterwards,on the base of the demand analysis the conceptual model is built and the conceptual model is transformed into relationship model.Ultimately,the engineering application of the system is illustrated by an example.The influence factors of the stability in the process of cutting are fully considered in this database and this system can provide reliable basis for parameters selection in machining.
