摘　　要：近年来,随着我国汽车工业的快速发展,并逐渐成为机械制造行业中的支柱性产业,而数控技术在汽车行业起到了举足轻重的作用,尤其是体现在重卡领域关键零部件的机械加工中。对于形状/结构简单的产品来说,为方便、快捷,数控加工程序通常采用手工编程来完成。文章以某重卡发动机支架为例,针对钻四个底孔和铣3°面的加工内容进行了研究。通过对产品加工工艺进行分析,制定了两种加工工艺方案,依据工艺方案,通过FANUC数控系统编程,对方案A和方案B两种手工编程方法进行了对比分析,经现场多次实践,并得出结论,方案B通过应用G68旋转指令,简化了编程难度,提升了编程效率,降低了编程出错率,为后续同类型产品提供了一个新思路、新方法。In recent years, with the rapid development of China’s automobile industry, which gradually becomes the mainstay industry in machinery manufacturing industry, the numerical control technology in the automotive industry plays a pivotal role, especially in the machining of key parts in the field of heavy trucks. For products with simple shape/structure, for convenience and speed, the numerical control machining programs are usually completed by manual programming. Taking the engine support of a heavy truck as an example, this paper studied the machining content of drilling four bottom holes and milling 3° surface. Through an analysis of product processing technology, two processing technology schemes were formulated. According to the process scheme, the two manual programming methods of scheme A and scheme B were compared and analyzed by FANUC numerical control system programming. After the field practice for many times, we concluded that by applying G68 rotating instructions, scheme B can simplify the programming difficulty, improve programming efficiency, reduce the error rate of programming and provide a new idea and method for the subsequent products of the same type.
