摘要数控机床可以加工各种各样复杂的零件，可以加工各种轴类零件、盘类等回转体零件，各种难以加工的工件。加工各种表面，比方说外圆柱面、圆锥面。加工各种螺纹，比方说圆柱螺纹、圆锥螺纹。还有各种复杂的切槽、钻扩、铰孔等复杂的工序，都可以在数控机床上进行加工。随着数控机床的广泛应用，人们越来越关心数控机床的工作效率、功耗以及安全性问题。根据中国机床工具工业协会组织用户调查表明，航天航空、国防军工制造业需要大型、高速、精密、多轴、高效数控机床；汽车、摩托车、家电制造业需求高效、高可靠性、高自动化的数控机床和成套柔性生产线；电站设备、造船、冶金石化设备、轨道交通设备制造业需求高精度、重型为特征的数控机床；IT业、生物工程等高技术产业需求纳米级亚微米级超精密加工数控机床；工程机械、农业机械等传统制造行业的产业升级，特别是民营企业的蓬勃发展，需要大量数控机床进行装备。这在我国数控机床来说，是一次挑战和机遇。因为数控机床是用计算机数字化信号控制的机床，其他机床难以加工的表面，比方说各种非圆曲面构成的回转面就可以用数控机床加工出来。所以数控机床是以后的发展大趋势，因为工人使用它，工人的劳动强度变轻松，生产工件将会更多，工厂的利益很大幅度提升，有利于生产办理现代化等长处。关键词：工艺分析；加工参数；工序卡；编程AbstractNumerical control machine can process a variety of complex parts, processing can be all kinds of shaft parts, plate, of axially symmetrical parts, such as in a variety of the workpieces. Outside the processing of surface, for example, tapered cylinder surface. Processing of thread, for example straight thread, taper thread. There are various kinds of complex cutting, drilling, reaming, such as expanding the complex process, can be processed on the nc machine tools.With the widely application of the engineering drilling machine, people are increasingly concerned with the work of drilling efficiency, power consumption and safety. The engineering drilling machine in working process, restricted by length of drill pipe, need to connect with continuously remove the drill pipe complete rated deep hole drilling. The engineering drilling machine of many current task is done by the workers loading and unloading drill pipe. The intensity of labor is very big, the efficiency is very low, at the same time due to the limitation of the engineering drilling machine working environment, workers in the process of operation construction accident rate is high. Therefore, design a kind of high efficiency, good safety automatic in rod system is particularly important. This thesis is encountered in the process of DTH drilling rig in the construction of bar, change long rod type problems such as designing a SWDB120 DTH drill library service
