- Touch Probe to be used with CNC machines
- Electrically is just a switch
- Mechanically, the switch is activated with minimal displacement from 3 axis.
- Implementation can be piezo, mechanical (bearing balls), optical
- It is used to sense the touching of the CNC to the material surface and get as data
- objects shape or end-points,
- machine ends
- Tools length
- It can be attached to CNC moving head at the tool chuck or next to it, or at the machine table
- CNC Touch probes are high priced precise instrumentation
- A low cost alternative is to make a relative precise home-made touch probe
