Abstract
In this paper, new mathematical models and grinding methods of ball-end milling cutter were proposed based on the orthogonal spiral cutting edge curve. In order to avoid interference, a conical wheel was also designed and employed to grind the rake and rear faces of ball-end milling cutter on a five-axis grinder. Mathematical models of both rake face with equal rake angle and rear face with equal clearance angle were established to improve the machining characteristics of ball-end milling cutter. The design and simulation software of ball-end milling cutter was developed to design and optimize different shapes of both rake face and rear face. Furthermore, grinding experiment of the new ball-end milling cutter was carried out to confirm the validation of the mathematical models.
