Abstract
High frequency vibrations of a boring bar cutting tip are minimized by use of a damping sandwich of plural layers of steel and plural alternate layers of viscoelastic solid material. This damping sandwich is placed at a joint in the machine tool between the cutting tip and a tool mounting area, and is shown as being provided between a mounting face of a tool mounting block and a mounting area. The damping sandwich permits greater depth of cut, with greater inches per revolution of chip removal without any chatter for improved metal removal.
