Parts of the Probing System
Parts of the Probing System

OMI
- Optical machine interface is tied in directly to the machine CNC control.
- The OMI or machine interface communicates with the other two probes by modulated infra red light.
- It acts as an optical receiver which sends and receives signals from the other two probes directly to the CNC machine control.
This picture shows the optical Machine Interface on the back of the VF2SS which can communicate with either the table or the spindle probe.
OMP
- Optical Machine Probe is a 3D triggered inspection probe that using a CAT40 tool holder    in the spindle.
- The OMP can be used to set work offsets and also to inspect parts.
- The probe will sense in 5 directions.

X + or -

Y + or -

Z +

- Set this probe to heavy tool (h) on the tool length offset page for safety reasons.
OTS
- Optical Tool Setter or also call the Table Probe
- This is used for tool lengths and diameters of tools.
- The OTS can also be used to check for broken cutting tools.
