OMP optical machine probe

1 Data sheet H A - optical machine probe The compact for CNC machining centres reduces set up times Critical part dimensions are measured and offsets updated to reduce scrap The controlled process with easy to use software can run unmanned maximising the potential for productivity gains Features Signal transmission The transmits through 3, at an angle of 90 to the spindle axis, with a range of up to 5 m (16.4 ft). Modulated transmission Now upgraded to include modulated transmission for increased resistance to light interference. Probe repeatability Repeatability of 1.0 µm 2σ ( in 2σ) is certified at 480 mm/min (1.57 ft/min) with 50 mm stylus. Probe switch-on Probe switch-on is by machine input. Probe switch-off Probe switch-off is user configurable between machine input and time off. Battery life A standard battery life of 140 hours continuous use, or the equivalent of over 85 days at 5 % usage is achievable. Battery life is increased when low power mode is selected. Visible probe diagnostic LEDs Provides on/off, seated/triggered and low battery information. Optical receivers Compatible with OMI and OMM (Legacy transmission) and OMI-2T/OMI-2/OMI-2H (Modulated transmission). Software for probe routines The is suitable for use with Renishaw single and double touch probing cycles. Twin probing A probe can be designated either as Probe 1 or Probe 2 for use in twin probe systems. Probe sealing Sealed to IPX8 and designed for the machine tool environment.

Stand-by mode - The is waiting for a switch-on signal to be received. 2. Operating mode - Activated by one of the switch-on methods described below. In this mode the is now ready for use. 3. Configuration mode - The Trigger Logic TM configuration method allows the following settings to be configured. Probe settings Enhanced trigger filter Probes subjected to high levels of vibration or shock loads may output signals without having contacted any surface. The enhanced trigger filter improves the probe s resistance to these effects. Optical transmission start mode The can be operated in either legacy or modulated optical transmission modes. In modulated mode, the becomes compatible for use with an OMI-2T, OMI-2 or OMI-2H, to provide substantially increased resistance to light interference. In modulated mode, it is possible to define the probe ID. This is factory set to Probe 1 but can be changed to Probe 2 for use with twin probe systems. In legacy mode the is compatible with OMI and OMM/MI 12. In legacy mode a selectable start filter improves the resistance to false turn on/off. Probe switch on/switch off method Switch on/switch off methods are configurable: 1. Optical on/optical off 2. Optical on/timer off These options are detailed in the table below. optical power Where the separation between and the receiver is small, the low optical power setting may be used. In this setting, the optical transmission range will be reduced as shown on performance envelopes to extend battery life. Dotted lines on performance envelopes represent the in low optical power. Probe switch on Probe switch off Optical switch on (when commanded by machine input) Optical switch on (when commanded by Auto start) Optical switch off (when commanded by machine input) A timer automatically switches the probe off after 90 minutes from last trigger if not turned off by machine input Timer off (time out) Time out will occur (12, 33 or 134 sec) after the last probe trigger or reseat Timer off (time out) Time out will occur (12, 33 or 134 sec) after the last probe trigger or reseat

3 Performance envelope The has a 3 transmission envelope over the ranges shown below. The probe system should be positioned so that the optimum range is maintained over the full travel of the machine axis. The and optical receivers may deviate from the optical centre line, provided opposing light cones always overlap, with transmitters and receivers in the other s field of view (eye to eye). Natural reflective surfaces within the machine may affect the signal transmission range. Coolant residue, accumulating on the receiver will have a detrimental effect on transmission performance. Wipe clean as often as is necessary to maintain unrestricted transmission. performance envelope with OMI-2T/OMI-2/OMI-2H (modulated transmission) Typical plot at 20 C (68 F) 3 transmission around probe axis in metres (feet) Optical centre line 0 0 OMI-2T/ OMI-2/ OMI-2H Range m (ft) Switch on/off Operating - standard Operating - low performance envelope with OMI (legacy transmission) Typical plot at 20 C (68 F) 3 transmission around probe axis in metres (feet) Optical centre line 0 0 OMI Range m (ft) Switch on/off Operating - standard Operating - low performance envelope with OMM (legacy transmission) Typical plot at 20 C (68 F) 3 transmission around probe axis in metres (feet) Optical centre line 0 0 OMM Range m (ft) Switch on/off Operating - standard Operating - low
