I think it is time to reveal my idea for a new lathe safety system. The idea is to prevent accidental contact or "crashes" between the tooling and the chuck. These events frequently damage the chuck and require regrinding or replacement of the tooling.
The system works like this. I have designed a sensor that attaches to the tool and monitors for contact with the chuThere is a control and switching module associated with the chuck. This module receives input from the tool sensor and triggers the safety system
Attached to the spindle is a shaped charge of C4 as shown. The geometry is designed to pyrotechnically sever the spindle in case of an incident.
A similar amount of C4 is mounted on the motor:
This image shows an overview of the hardware:
In case of a crash the shaped charge from the plastic explosive will sever the chuck from the spindle and/or disable the motor preventing operator injury and tool damage. This will undoubtedly save time and money on replacement tooling as well reducing work-site related injuries.
Any constructive comments regarding this design are welcome!
