组合机床是以通用部件作为基础，配以按工件特定形状和加工工艺设计的专用部件和夹具，组成的半自动或自动专用机床。组合机床多采用多轴、多刀、多工序、多面或多工位同时加工的方式，生产效率比通用机床高几倍至几十倍。由于通用部件已经标准化和系列化，可根据需要灵活配置，能缩短设计和制造周期。因此，组合机床兼有低成本和高效率的优点，在大批、大量生产中得到广泛应用，并可用以组成自动生产线。
本设计中选用的组合机床原来采用继电器控制系统，存在控制线路复杂、容易产生电气故障、维修困难且费用较高，而采用PLC控制系统则能克服上述缺点，减少电气故障，满足正常、稳定生产的要求。

Combination machine tool is common components as a basis for workpiece supported by the specific shape and design of the processing components and special fixture, The semi-automatic or automatic dedicated machine. Combination use of multi-axis machine tools, multi-knife, multi-process, multi-faceted public places or while processing approach production efficiency higher than generic machine several times or more. As generic components have been standardized and serialized and may need to be flexible configuration, can shorten design and manufacturing cycle. Therefore, the combination of both low-cost machine and the advantages of high efficiency, the large, mass production to be widely applied. which may be used to form automated production lines.
The design is chosen for a combination of the original machine used relay control system, there are complex control circuits, which can easily lead to electrical fault maintenance difficult and expensive, and the PLC control sy
