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 completed a investigation of internal and external of current situation for numerical control multistage-drilling machine, and compared it, put forward a feasible scheme; completed the mechanical structural design an calculated and designed the electric control system, and finished the software and hardware of the control system tentatively;
