You also need bodies to listen to the tool... ever since I build my small CNC machine I’ve learned just how important it is to listen to the cutting especially when you are doing adaptive passes to make sure your software doesn’t cock up the cuts.

This is probably the biggest area where i can see machine learning be actually useful with acoustic sensors.

I’m not an experienced machinist by any stretch of the imagination but even with my relatively small experience I can tell how good or bad the finish of a cut is going to be based on the sound the machine makes.

Great idea,, it already exists: https://en.m.wikipedia.org/wiki/CNC_machine_tool_monitoring_...

I would assume it does especially on 6-7 figure machines but I think even with basic microphones this might be a good application for ML at the small shop and hobbyist levels and I haven’t seen that yet.

Anyone know of reasonably priced acoustic emission sensors? Even on AliExpress I could only find transducers that start around 500 USD. Would love something closer to 50...

I'm not sure these are "reasonably priced" but these have been my favorite product in this are: https://endaq.com/collections/endaq-shock-recorders-vibratio...
