OMM TWIN MOUNTINGEach spindle of a twin spindlemachine can accept a probe.Although both OMM 1 andOMM 2 are switched on, onlyone probe may be used atany one time.

NoteOnly one O-M-I canbe used per machine.

OMM TANDEM MOUNTINGInstallations with exceptionally longspindle travel, may require a secondOMM to cover signal reception overthe probes full working envelope.The reception cones of OMM 1and OMM 2 overlap, so they actas one receiver.

REMOTE INDICATORA bleep is emitted from theMI 12 each time the stylus isdeflected or returns to rest.

Alternatively a remote lampor bleeper may be placed in aposition where it is easily seenor heard by the operator.

Dead battery indicationThe probe status LED indicates whenthe batteries have come to the end oftheir useful life.When the battery voltage dropsbelow a threshold whereperformance cannot be guaranteed,the probe status LED will change tocontinuous red.The probe output relay will alsobe forced into its open state, causingthe machine to stop, until newbatteries are inserted.The probe will revert to the stand-bymode after changing the batteries.

Low battery indicationThe MI 12 or O-M-I low battery LEDlights up when battery voltage is low.The low battery LED will onlyilluminate during the probe operatingmode. This will warn the user that theend of useable battery life isapproaching. The machine controlmay also be programmed to flag upa low battery alarm.

Typical battery reserve life.Using alkaline batteries at 5%usage, the probe will typicallycontinue to operate for 8 hours,after the low battery LED lights up.

STYLUS SPRING PRESSURE ADJUSTMENT AND

USE OF STYLI OTHER THAN CALIBRATION

STYLUS TYPE, MAY CAUSE REPEATABILITY TO

DIFFER FROM THE TEST CERTIFICATE RESULTS.

Spring pressure within the probe causesthe stylus to sit in one unique position, andreturn to this position following each stylusdeflection.Stylus pressure is set by Renishaw. Theuser should only adjust spring pressurein special circumstances e.g. excessivemachine vibration or insufficient pressureto support the stylus weight.The probe head detaches to provide accessto the spring pressure adjusting screw.First release the locknut, then turn theadjusting screw anti-clockwise to reducepressure or clockwise to increase pressure.

Finally tighten locknut to 1 Nm (0.74 lbf.ft).

Caution - Overtightening will eventuallyunseat an internal seal. To check if sealingis secure, press the stylus in, on release theprobe outer diaphragm should return to itsoriginal shape, any crumpling indicates thatthe internal seal is no longer effective.Turn the adjusting screw anti-clockwise toreseat the internal seal. Oil leakage aroundthe adjusting screw will also indicate overtightening.

1-19STYLUS ON-CENTRE ADJUSTMENT

How to check stylus positionStylus tip and stem position are establishedusing a low force (less than 0,2 N / 0,045 lbf.)dial test indicator or setting gauge.Alternatively rotate the stylus ball against aflat surface. Alignment is good when the stylusball maintains a consistent distance from theflat surface.

Stylus alignment with the spindle centreline need only be approximate, except inthe following circumstances.1. Alignment must be as exact as possible,

when probe vector software is used.2. The probe must be parrallel to the spindle

axis to prevent stylus stem contact whengauging deep holes.

3. When the machine control softwarecannot compensate for an offset stylus.

1. IF AT ANY TIME THE UNIT ISACCIDENTLY DROPPED, ITSHOULD BE CHECKED FORON-CENTRE POSITION.

2. DO NOT HIT OR TAPTHE PROBE TOACHIEVE ON-CENTREADJUSTMENT.

Stylus aligmentFirst remove the two probe front coverscrews, and remove the front cover.This provides access to four probe headholding screws.To adjust stylus alignment, slacken the probehead holding screws to allow the probe headto pivot on its spherical seat.Adjust and tighten these four screws tolock the probe head in its new position.Then check the new position for alignment.When the stylus is correctly aligned, checktightness of holding screws, and replace thefront cover.

Time outThe period during which the OMP will remainoperational before switching to stand-by, when inOptical on - Time out mode.

The time out is user selectable to 33 or 134 seconds- factory set to 134 seconds ±2 seconds.

Debounce timeSee OMP switches - pages 1-9 and 1-15.The debounce time, is the minimum time that mustelapse after sending a start signal, before the OMPis ready to act upon another start signal.

If a start signal is sent within the debounce periodthe OMP will ignore it. The debounce period afterthe OMP has been switched on, is user selectableto 5 or 9 seconds - factory set to 5 seconds.

The debounce period after the OMP has beenswitched off, or timed out, is less than 10 ms.i.e. It can be switched back on again, after 10 mshas elapsed.

The probe has two basic operating modes,which are user selectable.

1. Optical on - Optical off

2. Optical on - Time out (off)

DefinItion of termsThe terms and descriptions given below, definethe different phases of system operation.

The probe can only be used, if batteries withuseable life are correctly fitted in the OMP.

Stand-byWhen the OMP transmitter is off, and only thereceiver is active - waiting for a start signal.

Start signalA burst of infra red from the OMM or O-M-I,modulated at 7,8125 kHz, will switch on theOMP transmitter.

OperationalWhen the OMP is transmitting probe statusinformation, and the receiver is active.

SWITCH ON SWITCH OFF

1-23OPERATING MODES

OMP switch on optionsThe probe should be located in the machinespindle, and have a direct line of sight betweenits Rx diodes, and the OMM/O-M-I.

Switch on options are user selectable by MI 12or O-M-I switch settings - see MI 12 or O-M-Ihandbook.

OMP switch on is initiated by one of the followingmethods:

1. Manual start (Optical on) - MI 12 start button

2. Machine start (Optical on) - Optical switch onvia software M code command - factory set.

3. Auto start (Optical on) - Causes the system tosend an optical start signal once every secondand does not require a machine control input.

Note :Auto Start should not be selected when systemsare set to the Optical on - Optical off option.

OMP switch off optionsThere are two switch off options.Switch off options are user selectable by OMPswtich settings - see pages 1-9 and 1-15.

1. Optical on - Time out - factory setA timer automatically returns the OMP to thestand-by mode after 33 or 134 seconds.The timer is factory set to 134 seconds.The 33 second option is selected by changingthe internal OMP switch - see pages 1-9 and 1-15.

The timer is also reset for a further 33 or134 seconds each time the probe triggers duringthe operating mode.

Note : A start signal received during probe ontime also resets the timer (not during debounceperiod of 5 or 9 seconds).

2. Optical on - Optical offIn this mode a second start signal will return theOMP to the stand-by mode. Optical switch off iscommanded by a software M code.

The probe will remain off until the next switch oncommand. Switch off can only occur after the switchon debounce period has elapsed (5 or 9 seconds).


1-24PROBE MOVES

High probing speeds are desirable, however, a probingvelocity must be chosen which allows the machine tostop within the limits of stylus overtravel and measuringcapability of the machine.

CALIBRATING A SYSTEMCalibration should be done in the following circumstances :1. Before the system is used2. When a new stylus is used.3. If the stylus is bent.4. To allow for machine thermal growth.5. Poor relocation repeatability of the probe holder.

It is important that calibration cycles are run at the measur-ing cycle feed rate to cancel out system errors.

Make measurements in every measuring direction toprovide complete calibration data for the measuring cycles.

PROBE TRIGGERA probe trigger signal is generated when theprobe stylus is driven against a surface. Themachine control records the contact positionand instructs machine motion to stop.To ensure a trigger signal is given, drive theprobe against the workpiece to a target beyondthe expected surface, but within the limits ofstylus overtravel. After the probe stylus touchesthe surface, reverse clear of the surface.

SINGLE and DOUBLE TOUCH PROBINGIf the probe operating sequence is based on asingle touch, then the probe is returned to itsstart point following a measuring move.On some types of controller, it is desirable touse a two touch method as poor accuracy andrepeatability can result at higher feed rates.With a double touch sequence the first movefinds the surface quickly. Then the probe isreversed to a position clear of the surface,before making the second touch at a slowerfeed rate, thereby recording the surfaceposition at a higher resolution.PROBE MEASURING SPEEDThe probe system transmission delay timeis small and constant and does not normallylimit the probing speed, because it is cancelledout during calibration of the probe on themachine tool.

PROBE INTERFACE SIGNALS1. Error signal delayA delay of 48 ms maximum for the OMM + MI 12 or41 ms maximum for the O-M-I, will elapse betweenan error occurring and the output indicating error.

2. Probe signal delayThere is a nominal delay of 140 µs with a repeatabilityof 2 µs for each interface, from the time the probeactually operates to the MI 12/O-M-I interfaceindicating a probe change of state.Enabling the enhanced trigger circuit will adda further nominal 7 milliseconds.

SOFTWARE REQUIREMENTSProbe cycles and features are machine softwaredependant. Good software will allow the followingfunctions :

● 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 correctiveaction.

● Update work co-ordinate systems for positioning.● Report measured sizes and update tool offsets

for automatic tool offset compensations.● Print data in the form of an inspection report

to an external PC / printer.● Set tolerances on features.

VERIFY YOUR SOFTWARE1. Does your software have suitable calibration

routines which compensate for stylus on centreerrors. If not you must set the probe stylus oncentre mechanically.Note - Machining centre applications :When using probe styli which are not on spindlecentre, spindle orientation repeatability isimportant to avoid probe measurement errors.

2. Does your software compensate for probetriggering characteristics in all measuringdirections.

3. Does the software automatically adjust theprogram co-ordinate system to the relevantset-up feature on the component, for jobset-up purposes.

4. Does your software provide protected movesin the cycles to monitor for a collision.
