In order to solve the problem of the traditional way for machining drill’s end tooth, analyze the configuration of the universal tool grinding machine, study the component part of the drill’s end tooth, analyze the technological process of machining drill’s end tooth, exploit the parameter software based on SKX4-F CNC System. By means of inputting appropriate technological parameter and number, the CNC generate technological programs automatically. The applications show that the method can machining drill’s end tooth very well.
