A probing cycle may be included at any stage of the machining process.
6 System performance System performance RMP60 and RMP60M have identical user options and radio performance Operating envelope Radio transmission does not require line-of sight and will pass through very small gaps and machine tool windows. This allows easy installation, either inside or outside the machine enclosure. Coolant and swarf residue accumulating on the RMP60/M and RMI may have a detrimental effect on transmission performance.
System performance Probe repeatability Environment Maximum 2 Sigma (2σ) value. Repeatability of 1.0 µm (40 µ in) is valid for a test velocity of 480 mm/min (1.57 ft/min) at the stylus tip, using a stylus 50 mm (1.97 in) long. RMP60 IP rating IPX8 RMP60 weight (without shank) Without batteries With batteries 855 g (30.16 oz) 901 g (31.79 oz) RMP60M weight (without shank) Without batteries With batteries 690 g (24.34 oz) 736 g (25.
Operating envelope 8 Operating envelope RMP60 probe + RMI Always face the front cover of the RMI in the general direction of the machining area and the tool magazine, ensuring both are within the operating envelope. RMP60 and RMI must be within each other’s operating envelope. The operating envelope shows line-of-sight performance, however radio transmission does not require line-of-sight as long as any reflected radio path is less than the 15 m (49.

12 Probe settings Probe settings The RMP60 probe can be in one of three modes: Stand-by mode - The RMP60 is waiting for a switch on signal. Operating mode - Activated by one of the switch on methods described on this page. In this mode the RMP60 is now ready for use. Configuration mode - The trigger logic configuration method allows the following settings to be configured. Switch-on / switch-off methods The following switch on / switch off options can be configured: 1. Radio on / Radio off 2.
Probe settings Switch-on method Switch-off methods available Radio on Radio switch on when commanded by an M code. Radio off Radio switch off when commanded by an M code. 13 A timer automatically switches the probe off after 90 minutes from the last trigger if not turned off by an M code. Timer off (time out) Time out will occur (12, 33 or 134 seconds) after the last probe trigger or reseat. Spin on Spin at 650 rev/min for 1 second minimum (6 seconds maximum).
14 Multiple probe mode Multiple probe mode RMP60 can be user configured using trigger logic to allow multiple RMP60s to be used with a single RMI. Note: Radio turn on cannot be used in multiple probe mode. Only one of the multiple probes per machine will need partnering as, by configuring multiple probes to a single ‘mode-on’ choice, all probes have the same identification. The probe to be partnered, is partnered after selection of multiple probe on in ‘Changing probe settings’.

22 RMP60-RMI partnership RMP60-RMI partnership System setup is achieved using trigger logic and powering on the RMI. 1. Use trigger logic to access the RMP60 configuration mode. Trigger logic is a method that allows user configuration of the options available in the RMP60. Trigger logic uses a sequence of RMP60 triggering and battery insertion followed by further RMP60 triggering. 2. Configure the turn on method (if not configured).
RMP60-RMI partnership 8. Release the RMP60 stylus and trigger it a couple of times. This causes the RMP60 to go into (and out of) acquisition mode. 9. The RMI signal LED will change to repeatedly flashing red and yellow (for the remainder of the 10 second interval), indicating a successful partnering. 10. Leave the RMP60 for 20 seconds to go into standby. 11. The system is ready to use.
24 RMP60 batteries RMP60 batteries Replacing batteries Only use specified batteries. Clean and dry the RMP60 with a cloth or paper towel before removing the battery cover. Where the RMP60 has been exposed to coolant, it is recommended that the area around the battery cover is cleaned. To access the RMP60 batteries, remove the battery cover by rotating the securing screw 30° anticlockwise and withdraw the battery cassette. Take care to avoid damaging the cover gasket.
25 RMP60 batteries + - + Battery cassette Batteries 2 x AA DO NOT leave exhausted batteries in probe DO NOT allow coolant or debris to enter the battery compartment DO check for correct battery polarity ! Please dispose of exhausted batteries in accordance with local regulations. Do not dispose of batteries in fire.
Battery life expectancy 26 Battery life expectancy Typical battery life Using standard alkaline batteries at 5 % usage, typically the probe will continue to operate for approximately 1 week after a low battery warning is first indicated. Replace the batteries as soon as is practicable. BATTERY Two AA type SHANK/SPIN TURN ON After batteries are inserted into the RMP60, the LEDs will indicate the current settings.
Battery life expectancy 27 Low battery indicator The low battery warning will be signalled by the alternate blue flashing of the probe status LED when the end of the usable battery life is approaching. Simultaneously, the low battery LED on the RMI will be lit. Dead battery indicator When the battery voltage drops below the threshold where performance can no longer be guaranteed, the RMP60 probe status LED will change to constant red, followed by flashing red.
28 RMP60 shank mounting RMP60 shank mounting Probe to shank alignment dot (used when bobbin is fitted) Stage 1 RMP60 shank mounting If the RMP60 is not to be used with a shank switch, proceed from step 3. 1. Remove the plug from the rear of the RMP60 using pliers. A Bobbin Rear plug 2. Place the bobbin into the shank. B 3. Fully slacken the four screws A. 4. Grease the two screws B, and fit into the shank. 5. Fit the RMP60 onto the shank, and visually position it central relative to the shank. 6.
Stylus on-centre adjustment 29 Stylus on-centre adjustment (if required) Stage 2 On-centre adjustment 7. Each of the four screws A will move the probe relative to the shank, in the X or Y direction, as pressure is applied. Tighten individually, backing off after each movement. SHANK 4 mm AF 2.5 mm AF 8. When the stylus tip run-out is less than 20 µm, fully tighten screws B to 6 - 8 Nm (4.4 - 5.9 lbf.ft). 9.
30 Stylus trigger force and adjustment Stylus trigger force and adjustment Spring force within the probe causes the stylus to sit in a unique position, and return to this position following each stylus deflection. Stylus trigger force is set by Renishaw. The user should only adjust the trigger force in special circumstances, e.g. excessive machine vibration or insufficient force to support the stylus weight.
Diaphragm replacement 31 Diaphragm replacement RMP60 DIAPHRAGMS OUTER DIAPHRAGM INSPECTION The probe mechanism is protected from coolant and debris by two diaphragms. These provide adequate protection under normal working conditions. 1. Remove the stylus. The user should periodically check the outer diaphragm for signs of damage. If this is evident, replace the outer diaphragm. The user must not remove the inner diaphragm. If damaged, return the probe to your supplier. 2.
32 Diaphragm replacement OUTER DIAPHRAGM REPLACEMENT 6. Fit the new diaphragm over centre. 7. Locate the outer edge of the diaphragm to rest on the outer edge of the inner diaphragm. M3 screw 2.5 mm AF 1 Nm (0.74 lbf.ft) 8. Refit the front cover and the M3 screws. Cover 9. Refit the stylus and re-calibrate the probe.
33 RMP60M system RMP60M system LPE extension bar RMP60M is a special modular version of RMP60. It enables probe inspection of part features inaccessible to RMP60, by fitting selected adaptors and extensions as shown.
