I have recently have been put in charge in figuring out how to run CNC machines without supervision. We have UR robots to do so but my concern is the breaking of inserts in my CNC lathes. We run mostly bronze and iron material so we get a lot of cast parts where we have issues of Porosity and cracks in the material. So my inserts could last 20 parts or could last 5 and break and when there is no operator around it will damage all the other tools in the remaining toolpaths. Is there a force sensor out there that i could install in the machine to monitor an increase in load that would E-Stop the machine or is there a better way?
