A related question on cutter vibration measurement
(OP)
Hi
I have a related query to my post "Noise and Vibration in Vertical Milling Cutters". What is the best location/method to measure the milling cutter vibration?
- Is it through an accelerometer on the spindle bearing which houses the cutter spindle?
or some other mechanism such capactive probes, laser etc.?
I believe torsional vibration would be difficult to measure using these methods. Does torsional vibration also play an important role in radiating noise?
Thanks

RE: A related question on cutter vibration measurement
Torsional vibration measurement could not be monitored with a standard vibration sensor like an accelerometer, but it is possible to measure torsional with some additional instrumentation. Sometimes "normal" vibration is a by-product of torsional vibration. Torsional vibration has been shown to be very influential in radiated sound from drive train components on trucks and busses. I would guess that it could also be influential on radiated noise from a milling machine. Maybe a good Google search, or trying the Global "engineering" search engine could turn up something on torsional vibration with regard to machine tools.
