Abstract：The CNC Spring Forming Machine is a special machine for producing springs, while key-press panel is a operating interface for controlling the spring forming machines. This paper introduces a method of designing and realizing the key-press panel for CNC Spring Forming Machines. It uses pellicle panel switch as the form, PS/2 Protocol as the communicating method,and AT89S51 as the processing unit. This key-panel has key-lock function and it is flexible and convenient for using, satisfies the requires of industry spot very well. It also can be used widely in the control systems whose host computers are PC because of its universal quality.
