【摘要】 介绍了PowerMILL软件在汽车模具数控编程中的应用技巧,其中包括加工数模的导入,加工区域的划分原则,数控加工编程策略和长短刀分割技术,自动化程序的生成。通过程序编制减少由于刀具磨损，机床测刀误差造成的产品缺陷，达到程序能够在数控机床上加工自动化率到90%以上，这些技巧提高了数控加工无人化，自动化。对轿车侧围模具数控编程方法进行了相关分析和研究,并提出了一些改进性建议，以此实现数控机床加工自动化，对其它汽车模具的数控加工有一定的参考价值。更多还原

【Abstract】 This paper introduces the application of PowerMill in steam die numerical control programming application. Which includes the import of machining digital models, processing area division principle. Numerical control machining programming strategy and cutter segmentation technology, automatic program generation. Reduction through programming due to tool grining machine tool measurement error caused by product defects. TO achieve the program can be in the CNC machine tool processing automation rate to more than 90%. The techniques improve CNC maching unmanned,automated.The following will carry out the correlation analysis and research on the truss and row of the car side enclosure mold.And propose some improved construction. In the way CNC program processing automation is realized.It also has a certain reference value to the numerical control machining of other automobile die.更多还原
