Abstract

The main purpose of this paper was to integrate CAD-CAPP-CAD system with optimizing cutting parameters for machining mold die. Due to the complexity of the machining process injection mold, its optimization as well as its optimal control is difficult to perform. Optimization of the cutting process needs efficient means for determining the optimal cutting parameters in order to minimize machining time and simultaneously preserve the quality of machining surface. With the recent development in CAD/CAM software, manufacturing engineers can proceed with the process planning problems, without knowing functional relationship between process input and process output in advance. In this study, the machining simulation in CATIA is used to obtain the results as initial inputs of optimal analysis. The response surface methodology (RSM) is used to analyze the cutting parameters such as cutting speed, feedrate, radial and axial depth of cut, and machining tolerance. Then this process will be integrated into process chain system that we have developed in the previous research.
以最佳切削参数加工模具的CAD-CAPP-CAM集成系统
本文的主要目的是将CAD-CAPP-CAD系统与模具加工的切削参数优化相结合。由于注塑模具加工过程的复杂性,其优化和最优控制是难以实现的。切削工艺的优化需要确定最优切削参数的有效手段,以最大限度地减少加工时间,同时保持加工表面质量。随着CAD/CAM软件的发展,制造工程师可以在不知道工艺输入和工艺输出之间的函数关系的情况下进行工艺规划问题。在本研究中,使用CATIA中的加工仿真来获得结果作为优化分析的初始输入。采用响应面法(RSM)对切削速度、进给速度、径向和轴向切削深度以及加工公差等切削参数进行分析。然后将此流程整合到我们在前期研究中开发的流程链系统中。
