[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.
