Vibration Monitoring of CNC Machinery

Vibration Monitoring of CNC Machinery

(OP)
I am looking for information on Vibration Based Condition Monitoring of CNC machines. What are the most common maintenance issues with CNC machines and which of those can be detected using vibration?

RE: Vibration Monitoring of CNC Machinery

My VMC currently has a drive belt on the spindle that is a bit damaged. It gets loud when running at high speeds. I'd think, since I can hear it, an accelerometer could sense it.

RE: Vibration Monitoring of CNC Machinery

Vibrations can indicate most component mechanical faults including bearings, gears, belts (if present). It can be used for monitoring tool issues such as missing tool, loose tool, tool wear and tool breakage. Generally spindle balance and bearings are the primary focus. Saving maintenance costs may not be as important as maintaining product quality and production. If your company has CNC machines, then ask operators and maintenance personnel for their concerns and requirements. There are several vibration systems ranging from portable meters to online monitoring for machine condition and tool issues.
