 Bigger Bigger  Smaller Smaller  Reset Reset

Hello!
I am a cnc machinist looking for a way to add a layer of safety to my machine.  I have 2 issues that I believe could be solved with a single set of sensors (accelerometers).  I need to detect excessive vibration (from an improper tool load), or sudden shock of gear slippage such as can happen if the spindle fails to start after an automatic tool change and the non-rotating tool reaches the material.

It looks like I can get this from accelerometers, but I need to be able to calibrate so that normal operation does not cause unnecessary trips.

I am totally new to arduino, so even a nudge in the right direction would be great.

Thanks to all in advance!

To start, you will need to purchase an accelerometer break-out board, hook it up to an Arduino and start making measurements so that you know how everything works, and how vibrational levels will appear in the measurements during normal machine operation. There are many tutorials; a search for "arduino accelerometer" will produce lots of ideas.

Thank you!  I appreciate the reply.   
The more I have looked into this, the more I believe this is a doable project.
