本文对球形封头内、外球面及马蹄窝形焊接坡口的加工进行了研究,探讨了数控机床与普通机床交替完成同一工序及空间曲面三坐标轴联动的数控加工工艺方法。研究表明,这种方法不仅可以均衡关键机床的设备负荷,使工艺的可操作性与工艺的经济性更趋合理,而且通过对数控加工工艺的研究成功地编制了数控加工程序,加工出符合设计图纸要求的产品,并为类似件的加工提供了可靠的技术资料。

In this paper, the processing of spherical, spherical and horseshoe-shaped weld beveling was studied. The numerical control machining process that the CNC machine and the general machine tool alternated the same process and the three-axis coordinate of the space surface was discussed. The research shows that this method can not only balance the equipment load of the key machine tool, make the process operability and the process economy more reasonable, but also through the study of CNC machining process, CNC machining program has been successfully programmed, Drawings required products, and for the processing of similar pieces provided a reliable technical information.
