摘要
 目前，组合机床的需求量很大，国家鼓励其出口。而国内汽车工业的迅速发展也势必导致各类零部件加工量的增大。因此，组合机床可多刀、多轴、多面、多工位加工的优点就显得尤为突出。本设计就是在攻丝组合机床的设计基础上（比如攻丝加工设计、组合机床总体设计、夹具设计等），将PLC控制技术应用到其中，通过事先编制好的程序来实现攻丝加工要求，以便快速、简便地获得所要加工的零件。这种设计方案的优点在于所有被加工孔可一次加工完成，可大批大量生产，且生产时可实现无人加工或少部分人看管，也可进一步提高组合机床的自动化程度。

关键词：组合机床、攻丝、PLC控制技术、自动化

Abstract
 At present, the demand for the aggregate machine-tool is very big, the country encourages its exportation. But the rapid development of the domestic auto industry certainly will cause all kinds of spare parts to process the increase of quantity.  Therefore, the aggregate machine-tool may the multi-knives, multiple spindle, the multi-surface, the multi-locations processing merit appear for is still prominent. This design is in attacks the silk aggregate machine-tool in the design foundation (for instance to attack silk processing design, aggregate machine-tool system design, jig design and so on), applies the PLC control  technology to among, through the procedure which beforehand establishes realizes attacks the silk processing request, by fast, simple the components which obtains must process. This kind of design proposal merit lies in possesses is processed the hole to be possible a processing to complete, when large quantities of mass productions, also production may realize nobody processing or little the partial people safeguard, also may further enhance the aggregate machine-tool the automation.

Key words: The aggregate machine-tool,  attacks the silk,
  the PLC control technology,  the automation
