摘要
模具型面的加工品质是模具制造技术中的关键。在分析比较了高速切削时三轴联动数控加工方式和五轴联动数控加工方式的优缺点的基础上,指出了分区域3+2轴(亦称定位5轴)数控加工方式在模具型面高速切削应用上的优势。研究了分区域3+2轴数控加工方式在模具型面高速切削应用中的关键技术,包括刀轴矢量与加工表面法矢倾角的优化,模具型面加工区域划分和最佳刀轴方向设计。
Based on analyzing and comparing excellence and shortcoming of continuous 3-axis and continuous 5-axis numerical control machining,this paper shows the advantage of 3 ＋ 2-axis （ positional 5-axis） numerical control for zonal high-speed machining auto panel dies surface and makes a study of the key techniques of applying 3 ＋ 2-axis numerical control to high-speed machining auto panel dies shape surface such as optimizing tool axis obliquity with the normal of cutting surface, the machining zone partition and the optimization of cutter direction design.
