【 摘 要 】

This paper presents a detailed algorithm that can be used in grinding a ballend mill with a five-axis CNC grinding machine. To obtain a high-precision algorithm, a mill mathematical model is required before the profile of the mill gets parameterized. So the profile of the mill can be indicated by a group of parameters. We can set a unique local coordinates system for each grinding part. Then, with the mathematical model, the relative motions between the workpiece and the grinding wheel can be gotten. The NC code can be obtained easily. If we transmit the NC code to a simulation software based on openGL and make a 3D simulation before machining the mill, the NC code could get an effective test.
