System performance Operating envelope Surfaces within the machine may increase the signal transmission range. Coolant and swarf residue accumulating on the RMP60 and RMI may have a detrimental effect on transmission performance. Wipe clean as often as is necessary to maintain unrestricted transmission. When operating, do not touch with your hand, either the RMI cover or the probe glass window, as this will change the performance. Operation in extremes of temperature will result in some reduction in range. RMI position To assist finding the optimum position of the RMI during system installation, a signal strength indication LED is available on the RMI interface. RMI signal strength is displayed on an RMI multi-coloured LED. 6 Operating envelope Operating envelope RMP60 probe + RMI RMP60 and RMI must be within each others operating envelope shown. 75 90 75 60 45 Range metres (feet) OPERATING AND SWITCH ON/OFF 75 15 (49) 60 45 60 45 10 (33) 5 (16) 30 15 0 15 30 5

(0.47 in) 10 Modes of operation Modes of operation The RMP60 probe can be in one of three modes:

1. Stand-by mode - The RMP60 is waiting for a switch-on signal . 2. Operating mode - Activated by one of the switch on methods described on this page. In this mode and the RMP60 is now ready for use. 3. Configuration mode - The trigger-logic configuration method allows a number of RMP60 set-up options to be configured by triggering the RMP60, including the switch-off options described on page 25. RMP60 switch-on RMP60 power on/off Switch-on options are configurable

- see page 13. Three switching methods can be used. 1. Radio start Radio switch-on is commanded by M code. 2. Spin start Spin at 650 rev/min for 1 sec minimum

(maximum 6 sec) 3. Shank switch Note:

RMP60 will be turned on after 1 sec in all modes. Modes of operation 11 RMP60 switch-off Switch-off options are programmable 3. Spin stop Three switching methods can be used. 1. Radio stop Radio switch off is commanded by a M code.

(Only applies when radio turn on is selected). A timer automatically switches the probe off after 90 min from last trigger if not turned off by M-code. 2. Timer off (time out)

(Only applies when radio on/spin on mode is selected). The RMP60 will time out (12, 33 or 134 sec) after the last probe trigger or reseat.

(Only applies when spin on mode is selected). A timer switch automatically swiches the probe off after 90 min from last trigger off, if not spun off. 4. Shank switch

(Only applies when shank on mode is selected). Note:

After being turned on, the RMP60 must be on for a minimum of 1 sec (7 sec for spin off) before being turned off. 12 Reviewing current probe settings Reviewing current probe settings START Batteries removed from probe Insert batteries: note the LED sequence, which follows the form below Note This menu will be omitted if shank turn on has been selected SWITCH OFF METHOD setting START UP SEQUENCE Settings review RADIO or SPIN Short timeout 12 sec Medium timeout 33 sec Long timeout 134 sec LED TEST SEQUENCE The probe LEDs will always begin with a colour test SWITCH ON METHOD setting RADIO ON SHANK ON SPIN ON START UP SEQUENCE COMPLETE The battery status will be displayed and after 10 s the probe will return to stand-by mode BATTERY GOOD BATTERY LOW Configuration using trigger logic Configuration using trigger logic 13 START Remove batteries from probe. Hold stylus deflected and insert batteries. Release the stylus only after 15 seconds. The current probe settings review sequence, detailed on page 12 will always be displayed first.

(Note: Once the RMI has been acquired, the RMP60 will only show acquisition mode off) It is recommended that settings are reviewed after programming. See Reviewing current probe settings. Always keep a record of probe settings following any programming. These will be needed should the probe be replaced. ACQUISITION MODE ACQUISITION MODE OFF ON Settings record table Once configuration is complete, leave the RMP60 in triggered for 20 sec to save configuration and go to stand-by. Return to SWITCH ON METHOD menu Switch on method Switch off method Radio Shank Spin Radio/spin Short time out 12 sec Medium time out 33 sec Long time out 134 sec System setup/establishing RMP60-RMI partnership. RMP60-RMI partnership 15 Setup is done by using the RMP60 trigger logic and powering on the RMI at a particular time during the process.

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. This leads the user through a series of choices allowing selection of the required options. Reviewing of choices made can be made by battery insertion alone. See pages 12 and 13 for full details of reviewing probe settings and configuration using trigger logic. 1. Use trigger logic to set RMP60 turn on/ off modes as desired. 2. Use trigger logic to access RMP60 acquisition mode (light blue flashes, 2 short 1 long). Warning When holding the RMP60 do NOT wrap a hand, or anything else, around the glass window. 3. Power on the RMI. 4. Wait until RMI signal led flashes green. 5. Trigger the probe (min 0.1 sec max 2 sec) RMP60 will flash 2 x turquoise short, followed by 1 red long and repeat until acquistion occurs. 6. RMI pattern will change to red & yellow flashing when it acquires the RMP. 7. Allow ~10 seconds for both RMP60 and RMI to timeout all RMP60 LEDs off and RMI signal LED off. The system is then ready for use. continued on next page 16 RMP60-RMI partnership Note. When the RMP60 and RMI become partners the RMI records the RMP60 serial number. It is not possible for an RMI to be partners with more than one RMP60. It is possible for an RMP60 to be partners with more than one RMI, but the system will not work correctly if more than one partner RMI is powered on at any one time. RMP60 batteries 17 Do not mix new and used batteries or battery types, as this will result in reduced life and damage to the batteries. Always ensure that the cover gasket and mating surfaces are clean and free from damage, before reassembly. RMP60 batteries Replacing batteries Only use specified batteries. Clean and dry RMP60 with a cloth or paper towel before removing 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 battery cassette. Take care to avoid damaging the cover gasket. When inserting the batteries, ensure they are loaded as shown (see next page). If one or more batteries are incorrectly loaded the probe will not respond. 18 RMP60 batteries Battery cover

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 19 Battery life expectancy Alkaline - Two AA type (see page 20). Typical battery reserve life Using the standard alkaline battery at 5 % usage, typically the probe will continue to operate for approximately 2 weeks after a low battery warning is first indicated. Replace the batteries as soon as is practicable. When inserting new batteries the RMP60 will flash to show current configuration (page 12). In order to achieve stated radio stand-by life, the RMP60 must be in range of powered partner RMI. BATTERY SHANK/SPIN TURN ON RADIO TURN ON CONTINUOUS USE Two AA type STAND-BY LIFE

Simultaneously, the low battery LED on the RMI will be lit. Dead battery indicators When the battery voltage drops below the threshold where performance can be guaranteed, the RMP60 probe status LED will change to constant red. Battery specification The RMP60 requires two identical AA size batteries, individually rated at a voltage of between 1.2 V and 3.6 V. The standard batteries are AA alkaline. Alternative batteries are lithium thionyl chloride (3.6 V), NiCad or NiMh. For applications requiring maximum battery life, a high capacity lithium thionyl chloride type is essential.

Remove plug from rear of RMP60 using pliars. 2. Place bobbin into shank. 3. Fully slacken four screws A. 4. Grease two screws B, and fit into shank. 5. Fit RMP60 onto the shank, and visually position centrally. 6. Tighten screws B to 6-8 Nm (4.4- 5.9 lb.ft)

(Partially tighten screws B to 2 - 3 Nm

(1.47 - 2.2 lbf.ft), if RMP60 is to be on-centre adjusted). 7. The RMP60 assembly is ready for use. Note :

1. DURING ADJUSTMENT CARE SHOULD 2. BE TAKEN NOT TO ROTATE THE RMP60 RELATIVE TO THE SHANK. IF A RMP60/SHANK UNIT IS ACCIDENTALLY DROPPED, IT SHOULD BE CHECKED FOR ON-CENTRE POSITION. 3. DO NOT HIT OR TAP THE PROBE TO ACHIEVE ON-CENTRE ADJUSTMENT. A B Bobbin Switch 22 Stylus on-centre adjustment Stylus on-centre adjustment (if required) Stage 2 On-centre adjustment 8. 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. 9. When the stylus tip run-out is less than 20 m, fully tighten screws B to 6 - 8 Nm

(4.4 - 5.9 lbf.ft). 10. For final centering use screws A to move the RMP60, progressively slackening on one side and tightening the opposite screw, as the final setting is approached, using two hexagon keys. Tip run out of 5 m (0.0002 in) should be achievable. 11. It is important that all four screws A are tight or tightened to 1,5 - 3,5 Nm

(1.1 - 2.6 lbf.ft) once the final setting has been achieved. 2,5 mm AF A 4 mm AF B Stylus trigger force adjustment 23 Stylus trigger force adjustment Spring force within the probe causes the stylus to sit in one unique position, and return to this position following each stylus deflection. Stylus trigger force is set by Renishaw. The user should only adjust trigger force in special circumstances e.g. excessive machine vibration or insufficient force to support the stylus weight. To adjust trigger force, and turn the adjusting screw anticlockwise to reduce force (more sensitive) or clockwise to increase force

(less sensitive). A stop prevents damage, which could be caused by overtightening the adjusting screw. Increase force 2 mm AF Reduce force 24 Probe moves Probe moves Probe trigger A probe trigger signal is generated when the probes stylus is driven against a surface. The machine control records the contact position and instructs machine motion to stop. To ensure a trigger signal, drive the probe against the workpiece to a target beyond the expected surface, but within the limits of stylus overtravel. After the probe stylus touches the surface, reverse clear of the surface. Single and double touch probing If the probe operating sequence is based on a single touch, then the probe is returned to its start point following a measuring move. On some types of controller, it is desirable to use a two touch method, as poor accuracy and repeatability can result at higher feed rates. With a double touch sequence the first move finds the surface quickly. Then the probe is backed off to a position clear of the surface, before making the second touch at a slower feed rate, thereby recording the surface position at a higher resolution. Probe measuring speed The probe system transmission delay time is small and constant. It does not normally limit the probing speed, because it is cancelled out during calibration of the probe on the machine tool. High probing speeds are desirable, however if used, a probing velocity must be chosen which allows the machine to stop within the limits of stylus overtravel, and measuring capability of the machine. Probe moves 25 It is important that calibration cycles are run at the measuring cycle feed rate to cancel out system errors. Z Calibration measurements should be made in every measuring direction to provide complete calibration data for the measuring cycles. X/Y X/Y Probing cycles are available from Renishaw Calibrating a system Probe interface signals 1. Error signal delay A delay of 28 ms maximum for the RMI, will elapse between an error occurring and the output indicating error. Calibration should be done in the following circumstances:

2. Probe signal delay 1. Before the system is used 2. When a new stylus is used. 3. To allow for machine thermal growth. 4. Poor relocation repeatability of the probe holder with machine spindle. There is a nominal delay of 10 ms with a variation of 10 s for an interface, from the time the probe actually operates, to the RMI interface outputting a probe change of state. 26 Software requirements Software requirements Probing cycles and features are machine software dependant. Good software will allow the following functions :

Simple to use cycles Update a tool offset If an out of tolerance is found, either generate an alarm stop, or set a flag for corrective action Update work co-ordinate systems for positioning Print data in the form of an inspection report to an external PC / printer Set tolerances on features Verify your software Does your software have suitable calibration routines which compensate for stylus on-centre errors? If not, you must set the probe stylus on-centre mechanically. Note: Machining centre applications :

When using probe styli which are not on spindle centre, spindle orientation repeatability is important to avoid probe measurement errors. Inspection cycle features Simple to use canned cycles for standard features :
