Compact high-accuracy 3D measurement touch probe for a wide range of machining centres.

About RMP600

Strain gauge structure The Renishaw RMP600 is a compact, high accuracy touch probe with radio signal transmission, offering all the benefits of automated job set-up, plus the ability to measure complex 3D part geometries on all sizes of machining centres including 5-axis machines.

The RMP600 successfully combines the patented Rengage™ strain gauge technology with the unique frequency hopping radio transmission system from the RMP60.

Strain gauges attached to the structure measure the smallest of stylus motions, allowing for a very sensitive system.

This innovative RENGAGE™ technology built into the RMP600 brings unrivalled performance in terms of 3D measurement. Use the RMP600 with Renishaw OMV for advanced on-machine verification when machining contoured surfaces and complex shapes.

The 2.4 GHz frequency band is compliant with radio regulations in the EU, USA, Japan, Canada, Switzerland, Australia, New Zealand.

RMP600 features and benefits

Patented RENGAGE™ technology gives very low and highly consistent contact forces as well as Sub micron 3D performance on contoured surfaces
Increased stylus lengths can be supported without a significant decrease in probe performance
Frequency hopping spread spectrum (FHSS) transmission means that once partnered, the RMP600 and RMI hop frequencies together to provide reliable communications
The RMP600 utilizes accelerometers to detect shock and motion to assess whether stylus forces are due to valid triggers or high speed acceleration
Multiple probe mode is available on RMP600 to allow the use of many different probes with the same RMI receiver
3D performance is ideal for the calibration and mapping of 5-axis machines

* Performance specification is for a test velocity of 240 mm/min (9.45 in/min) with a 50 mm carbon fibre stylus. Test velocity does not constrain performance in application.

** The stylus trigger force is the force exerted on the component when the probe triggers. However, the maximum force applied to the component will occur after the trigger point and will be greater than the trigger force. The magnitude depends on a number of factors affecting probe overtravel including measuring speed and machine deceleration. If the forces applied to the component are critical, contact Renishaw for further information.

§ Stylus overtravel force in XY plane occurs 40 µm after the trigger point and rises by 0.19 N/mm, 19 gf/mm (17 oz/in) until the machine tool stops (in the high force direction and using a 50 mm carbon fibre stylus).

† Stylus overtravel force in + Z direction occurs 7 µm to 8 µm after the trigger point and rises by 1 N/mm, 102 gf/mm (76.2 oz/in) until the machine tool stops.
