Development of an active boring bar for increased chatter immunity
- Sandia National Labs., Albuquerque, NM (United States)
- Univ. of Florida, Gainesville, FL (United States). Dept. of Mechanical Engineering
The development and initial evaluation of a prototype boring bar featuring active vibration control for increased chatter immunity is described. The significance of active damping both normal and tangential to the workpiece surface is evaluated, indicating the need for two axis control to ensure adequate performance over expected variations in tool mounting procedures. The prototype tool features a commercially available boring bar modified to accommodate four PZT stack actuators for two axis bending control. Measured closed-loop dynamics are combined with a computer model of the boring process to simulate increased metal removal rate and improved workpiece surface finish through active control.
