摘　　要：汽车零配件形状复杂,编程人员仅凭经验选择数控加工的切削用量,导致切削用量的合理性因人而异,加工效率难以保证。为系统研究汽车零配件机械加工工艺特征对最佳切削用量选择的影响,在切削加工有限元仿真的基础上,开发汽车零配件工艺特征切削数据系统,并与UG CAM模块集成,形成基于UG数控编程的汽车零配件工艺特征切削数据系统。根据汽车零配件机械加工要求对工艺特征进行分类;采用Deform 3D有限元仿真并通过多元回归分析获得工艺特征参数、切削用量和刀具几何参数对切削温度的影响规律;根据马卡洛夫切削温度守恒定律获得最佳切削用量,并通过VC++软件开发获得汽车零配件-工艺特征切削数据系统软件。结果表明:该系统软件可有效解决编程人员凭经验选择切削用量,导致切削用量选择不合理、加工效率低的问题。Automobile parts have complex shape,the cutting amount in numercial control( NC) machining are traditionally selected based on experience of programmers,which will lead to rational amount of cutting personal dependent,so the machining efficiency is difficult to ensure. In order to systemtically study the influency of processing features in machinery machining of automobiole parts on selection of optimal cutting amount,based on finite element simulation of cutting machining,cutting data system for automobile parts based on processing features was developed. By integrated in UG CAM module,the data system based on UG NC programming was formed. The process features were classified according to the requirements in machinery machining of automobile parts. The laws of influence on cutting temeprature by precessing feature parameters,cutting amount,as well as cutting tool geometry parameters were obtained by using Deform 3D finite element simulation and through multielement regressive analysis. Optimization of cutting amount was obtained based on Makarov cutting temperature conversation law,the process features cutting data system software of automobile parts was developed by VC++ software. The results show that this system softwrae can effectively solve the problems of unreasonable cutting amount selection and low machining efficiency from experienced programmers.
