In order to improve the degree of automation of the gear chamfering process and the reuse rate of the software frame structure

based on the hierarchical state machine theory

quantum frame theory and embedded system implementation technology

a numerically controlled gear chamfering is proposed to design methods of angle control system. Hardware part of the system mainly includes an industrial control computer

solid high GTS series eight-axis motion card

and an open CNC system for gear chamfering. Software part introduces the relevant content of the quantum frame

and gives the organization structure of the quantum frame and the system diagram of the gear chamfering numerical control system. Finally

a processing software capable of logically controlling the chamfering machine was developed. Tests show that the gear chamfer CNC system designed by quantum frame technology has higher reliability

and reduces the difficulty of developing and designing control system software.
