Abstract
Techniques and apparatuses to provide vibration reduction of a workpiece when performing machining operations are disclosed. In various embodiments, a machine tool includes a shank having at least one end configured for engagement with a machine operable to rotate the shank. A cutting portion has a diameter defined by features used to remove material from a workpiece. The cutting portion is coupled to the shank. A vibration reduction dampener may be located between the shank and the workpiece.
Claims11
A method, comprising:
- engaging a machine tool to a machine operable to rotate the machine tool about a longitudinal axis of the machine tool, the machine tool comprising:
- a shank having a first end and a second end, the first end configured for engagement with the machine and the second end being distal from the first end;
- and
- a cutting portion proximate the second end of the shank, the cutting portion having a first diameter defined by one or more features used to remove material from a workpiece;
- placing a vibration dampener between the shank of the machine tool and the workpiece, the vibration reduction dampener formed from a compressible material and securely positioned on the shank at a location between the first end and the cutting portion and having a second diameter, greater than the first diameter, such that, upon machining engagement of the cutting portion to the workpiece, portions of the vibration reduction dampener are compressed against the workpiece and an axially-extending surface of the shank at a location between the workpiece and the axially-extending surface of the shank to dampen vibrations;
- and
- performing work on the workpiece by rotating the machine tool, where the vibration dampener absorbs vibrations of the workpiece that are caused by the performed work.
