A novel method for flute grinding of conical end milling cutter.

Conical end milling cutter is used more and more widely in NC machining. The flute is an important feature of the milling cutter, which directly affects the cutting performance of the milling cutter. However, the conical flute belongs to a complex spatial helix surface. In the machining process, the relative motion of the wheel and milling cutter is complex. To solve this problem, this paper presents a trajectory calculation method for grinding the flute of conical milling cutters. Firstly, the conical cutting edge line is deduced, and the position of the wheel in the whole grinding process is calculated under the design requirements of the rake angle and the core radius. Secondly, a method for calculating the flute profile of complex flutes is given. Finally, the effectiveness of this method is verified by numerical simulation, and it can also be extended to more complex flute grinding in future research. [ABSTRACT FROM AUTHOR]
