ABSTRACT:
Disclosed is a tunable damping system for use in reducing vibrations associated with metal cutting and tooling. The tunable damping system may be located in a boring bar, an end mill, a modular tool section or the spindle/tool holder of the metal cutting machine. The tunable damping system incorporates a damper mass, elastomeric supports, and a means to lock the mass so as to determine tuning parameters. A tuner assembly consists of sensors and a microprocessor capable of recognizing the most dynamically flexible mode of vibration. The tuner assembly is also capable, through signal processing and microprocessor controlled algorithms, to direct the operator in implementing the proper tuning adjustments of the tunable damping system.
