Increased process damping via mass reduction for high performance milling |
摘要 |
A cutting tool incorporates a body terminating in cutting edges distal from a chuck mount and having an axial bore for reduced mass to raise the natural frequency of the tool. In certain of the embodiments, the body is preformed from a steel or carbide blank into a cylindrical pipe forming the hollow bore prior to grinding of the cutting edges. Filling of the bore with a light weight polymer to further absorb vibration can also be employed. |
