4.2 Probe Mounting

Mount the OMP40-2 probe into the machine spindle using the appropriate tool holder.
Ensure the probe is securely seated and aligned.
Refer to your machine tool's manual for specific spindle mounting procedures.

4.3 System Pairing and Calibration

The OMP40-2 probe communicates optically with a receiver unit on the machine. Follow these general steps:

Power on the machine tool and the probe system receiver.
Initiate the pairing sequence as per the machine tool controller's instructions and the OMP40-2 quick start guide.
Perform a calibration routine using a known reference artifact (e.g., a calibration sphere) to establish probe offsets and ensure measurement accuracy.
Verify successful communication and calibration before proceeding with measurements.

5. Operating Instructions

The Renishaw OMP40-2 probe is designed for automated measurement cycles. Operation is typically controlled via the machine tool's CNC program.

5.1 Workpiece Set-up

Use the probe to accurately locate workpiece datums (e.g., edges, bores, surfaces) before machining operations.
This allows for precise alignment of the workpiece with the machine's coordinate system, reducing manual setup time and errors.

5.2 In-Process Measurement

Integrate probing cycles within machining programs to measure critical features during the manufacturing process.
This enables adaptive machining, where subsequent operations can be adjusted based on real-time measurements, improving part quality and reducing scrap.

5.3 Post-Process Inspection

After machining, use the probe to perform final inspection of part dimensions and geometry directly on the machine.
This provides immediate feedback on part quality and can eliminate the need for separate inspection steps.

Note: Always ensure the probe stylus is clean and undamaged before any measurement cycle. Refer to your machine tool's programming manual for specific G-code or macro instructions for probing cycles.

6. Maintenance

Regular maintenance ensures the accuracy and reliability of your Renishaw OMP40-2 probe.

6.1 Cleaning

Probe Body: Wipe the probe body with a clean, soft cloth. Avoid using harsh chemicals or abrasive materials.
Stylus: Gently clean the stylus tip with a lint-free cloth. Ensure no debris is present on the ruby ball.
Optical Window: Keep the optical transmission window clean and free from coolant or debris to ensure reliable signal transmission.

6.2 Battery Replacement

Replace batteries promptly when the low battery indicator is observed (refer to your machine interface for indicator details).
Always use recommended 1/2 AA Lithium batteries for optimal performance and battery life.
Dispose of used batteries according to local regulations.

6.3 Stylus Inspection and Replacement

Periodically inspect the stylus for wear, damage, or signs of impact.
A damaged stylus can significantly affect measurement accuracy and must be replaced immediately with a genuine Renishaw replacement stylus.
After stylus replacement, always perform a full probe calibration.

7. Troubleshooting

This section addresses common issues you might encounter with your OMP40-2 probe.

Problem	Possible Cause	Solution
No signal/communication loss	Low batteries, obstructed optical path, probe out of range, receiver fault.	Check/replace batteries. Clean optical window on probe and receiver. Ensure probe is within receiver's line of sight and operating range. Consult machine tool manual for receiver diagnostics.
Inaccurate measurements	Uncalibrated probe, damaged stylus, debris on stylus, thermal drift, machine geometry errors.	Perform probe calibration. Inspect and replace damaged stylus. Clean stylus tip. Allow machine to reach thermal stability. Verify machine tool accuracy.
Probe not triggering	Stylus stuck, probe damaged, incorrect trigger force setting (if adjustable).	Inspect stylus for obstruction or damage. If probe is damaged, contact Renishaw support. Check machine parameters for trigger force settings.

For issues not listed here, or if solutions do not resolve the problem, contact Renishaw technical support or your authorized distributor.
