A study is made of the forming theories and the computer aided design of the rotary cutting burs, for the purpose of finding the movement of the machining system and the corresponding sectional curvature of the groove conveniently. The equation of the cutting edges on the tool surface is deduced in this paper. The contact condition between the cutting edge of the tooth of the cutter and the grinding wheel is found, and the equation of the contact condition is deduced as well. Then the section line of the cutting edges of the rotary burs after CNC controlled machining is calculated. The research is useful for the programming of the CNC grinding on the CNC controlled machine tool.

Research on parametric modeling and grinding methods of bottom edge of toroid-shaped end milling cutter AbstractFor a toroid-shaped end milling cutter to have multi-structure features of tooth offset center and introversion of bottom edge, this paper proposes a generalized parametric modeling method of the bottom edge, including a straight edge segment and a circular arc edge segment. And based on the parametric model this paper also deduces the corresponding tool path for grinding of the bottom edge's rake and flank faces. The parametric modeling method is based on the geometric analytic equations while the grinding method is driven by the proposed parametric model and the parameters of rake and flank faces. The two methods can be applied to a bottom edge of a cutter with multi-structure features to guarantee G 1 continuity at the two joints for connecting a circular arc edge with a straight edge and a conical helix edge respectively. In order to verify the accuracy of proposed methods, experiments were carried out. The modeling and grinding experimental results verified the accuracy and utility of the methods.

Ball-end milling cutter with tooth offset center is widely used in machining industry, because it has higher machining efficiency and better stability compared with the ball-end milling cutter without tooth offset center. In addition, the tooth offset center has lower wear rate of the tool tip so the life of the milling cutter is improved. However, up to present, there is no mature and effective theory for the design and manufacture of this kind of milling cutters. This article presents a new mathematical model for S-shaped edge curve of the ball end taking the tooth offset center into account, which can construct accurate S-shaped edge curve for the ball-end cutting tools with tooth offset center as well as without tooth offset center. This model overcomes the complex computation and bad adaptability of the traditional modeling method. At the same time, a five-axis grinding algorithm for rake face of the ball end is also presented in this article. Finally, based on the application programming interface of CATIA™, a three-dimensional computer-aided design and computer-aided manufacturing system is developed. The accuracy and effectiveness of the grinding algorithm are verified by simulation in VERICUT™ and machining experiment in tool grinding machine.
