Milling tools or milling cutters are made by grinding. It uses 5 or 6-axis grinding machine. However, it is difficult to calculate the desired
wheel position and trajectory, so the parameters are determined by trial and error or past experience. It is inconvenient and inefficient, especially
when making a new shaped tool. For a more flexible tool design, a more convenient and efficient way to get the operating parameters is needed.
In this paper, the groove of the 2-flute end mill is considered as the target to calculate the machining parameters of the grinding wheel and its
shape. The basic principle is groove prediction and evaluation with goals and optimization to minimize the difference. Groove shape is predicted
rapidly by using graphic methods and GPU, and it contributes to speed up the optimization process. By evaluating the core radius, rake angle,
and whole groove shape, wheel position and wheel shape are optimized. The results of the experiment, core radius, and wheel position are
optimized enough, therefore core angle and rake angle are met to target value. The whole groove shape remains a slight difference but it is
considerable progress from the current production site.
