数控多工位钻床设计
 [摘要] 
随着先进制造技术的发展和进步，数控加工已成为机加工过程中的一种主流技术。这一技术的运用提高了机加工过程中工作效率和加工精度。数控多工位钻床就是提高钻削加工精度和效率的一种很好的机加工工具。本文对数控多工位钻床进行了设计，采用了普通车床设计的步骤和方法，综合考虑数控机床的特点。从切削力入手确定主轴及电机，到整个机床的结构设计和机床的控制。最后到对机床初始化程序设计。
本文所做的工作:
1.完成数控多工位钻床的资料收集与国、内外现状的调查比较，提出较为可行的方案;
2.完成机床的机械结构设计计算与电气控制系统设计，初步完成控制系统的软硬件设计；提交论文及机械系统的装配与关键零部件的相应图纸及数控系统的硬件图，同时提交电子文档;
3.编写设计计算说明书。
完成了一台经济型的数控机床的设计。

[Abstract] 
With the manufacturing development, numerical control manufacturing has become one of the major advanced technologies. efficiency and accuracy has been improved in application of the technology. Numerical control auto-drilling machine is a kind of the new machine tools that can improve the machining accuracy and efficiency. The paner has designed for Numerical control auto-drilling machine, using design method of the ordinary lathe, and considering the characteristic of the numerical control machine tools synthetically. cutting force has been calculated, the structural and the control system has been designed. Finally, the software routine has been explored.
This paner has finished major works:
1. Completed a investigation of internal and external of current situation for numerical control multistage-drilling machine, and compared it, put forward a feasible scheme;
2. Completed the mechanical structural design an calculated and designed the electric control system, and finished the software and hardware of the control system tentatively; Submit thesis and the assembly of mechanical system and hardware picture of key spare part and drawing of numerical control system, submit the electronic file at the same time;
3. Write the specification of designing and calculating, has designed an economy numerical control machine tool.
