Abstract

The flute plays an important role in the design process for tools. The complexity of the cutting edge is increasing continuously. Thus, it is difficult to grind flute precisely and efficiently. This paper presents a practical grinding method for the flute of tools. It solves the issue of how to grind the flute with the complex edge by standard wheels. It is summarized as follows: the curve of cutting edge and core are used as the designed parameters of the flute; we propose the fundamental conditions that the wheel does not interfere with designed parameters; we can find the posture and position of wheel in the curve frame easily, thus obtaining wheel trajectory. Finally, using a taper end mill as an example, the results show a good agreement between the CAM data and the model data. This proves the effectiveness of this method.
