OMP40-2 installation guide

Introduction
Welcome to the OMP40-2 job set-up and inspection probe, an upgrade of the multiple award winning OMP40. At only 40 mm diameter this compact probe sets industry standards for functionality, reliability and robustness in the harshest of machine tool environments. The OMP40-2 is ideal for small to medium machining centres including the growing range of HSK machines. Legacy or modulated transmission modes Modulated transmission is a method of sending signals from the probe to the interface to reduce the effects of light interference that in certain circumstances could cause false triggers in earlier legacy systems. Modulated transmission is capable of providing two different coded start signals. This allows the use of two probes with one interface. Twin probe installations require an OMI-2T interface. Twin probe system To operate a twin probe system, one probe needs to be set to probe 1 start and the other set to probe 2 start, these settings are user configurable. In a twin probe system such as a spindle probe and an optical tool setting probe, the spindle probe would be set to probe 1 start and the tool setter would be set to probe 2 start. Trigger Logic? The user can configure probe settings quickly and easily by deflecting the stylus in a sequence until the correct colour configuration is observed on the LED display, this programmable method is known as Trigger Logic?.
OMP40-2 basics

Probe settings
Configurable settings on the OMP40-2 are: ? ? ? switch-off method: enhanced trigger filter setting: optical transmission method and probe identity (ID): optical power:

2.2

?

Modes of operation NOTE: A visual indication of currently selected probe settings is provided, on battery insertion, by the three multicolour LEDs located within the probe window (see Section 4 - Trigger Logic?).

The OMP40-2 has three modes: Standby mode: where the probe is awaiting a switch-on signal: Operational mode: where the probe has been activated: Configuration mode: where Trigger Logic? may be used to configure the probe settings.

Probe settings continued
OMP40-2 basics

Switch-on/switch-off methods

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 probes resistance to these effects. When the filter is enabled, a constant 10 ms delay is introduced to the probe output. This is factory set to trigger filter off. NOTE: It may be necessary to reduce the probe approach speed to allow for the increased stylus overtravel during the extended time delay.

Switch-on method Optical on Optical switch-on when commanded by an M code.

Switch-off methods available Optical off Optical switch-off when commanded by an M code. Note: This option is required when operating a twin probe system with OMI-2T. Note: A timer automatically switches the probe off after 90 minutes from the last trigger if not turned off by an M code.

2.3

Optical on Optical switch-on when commanded by an M code, or when commanded by an auto start.

Timer off (time out) Timer off 1 12 seconds Timer off 2 33 seconds Timer off 3 134 seconds Note: Time out is factory set to 134 seconds and will occur after the last probe trigger or reseat. Note: Ensure that the probe does not remain active in the tool changer when optical on/time out option is selected by observing the LEDs.

OMP40-2 basics

Optical transmission method The OMP40-2 can be operated in either legacy or modulated mode. The modulated mode has a higher resistance to light interference. Certain forms of light interference can cause false triggers or mimic a start signal and falsely activate the probe. These effects are much reduced when modulated transmission is selected. Legacy mode When set to legacy mode, the probe will only function with an OMI or OMM/MI 12. If start problems are experienced in legacy mode, activate the Legacy Start Filter ON option. This introduces a 1 second delay to the probe switch on time, and improves the probes resistance to false starts caused by light interference. NOTE: The probing program on the machine will need to take account of this delay.

Low optical power Where the separation between the OMP40-2 and the receiver is small (no more than 2 metres), the low optical power setting may be selected. This setting will reduce the optical transmission range and extend battery life. Factory setting is standard power.

2.4

Modulated mode When set to modulated mode, the probe will only function with an OMI-2, OMI-2T OMI-2H or OMI-2C interface. For most applications the spindle probe should be set to probe 1 start. Probe 2 start should only be selected for a secondary spindle probe in a twin probe application.

All Renishaw equipment is designed to comply with the relevant EEC and FCC regulatory requirements. It is the responsibility of the equipment installer to ensure that the following guidelines are adhered to, in order for the product to function in accordance with these regulations: ? any interface MUST be installed in a position away from any potential sources of electrical noise, i.e. power transformers, servo drives etc; all 0V / ground connections should be connected to the machine 'star point' (the 'star point' is a single point return for all equipment ground and screen cables). This is very important and failure to adhere to this can cause a potential difference between grounds; all screens must be connected as outlined in the relevant user instructions; cables must not be routed alongside high current sources, i.e. motor power supply cables etc, or be near high speed data lines;

?

cable lengths should always be kept to a minimum.

The probe and receiver must be in the other's field of view, and within the performance envelope shown. The OMP40-2 performance envelope is based on the receiver being at 0°, and vice-versa. Natural reflective surfaces within the machine may change the signal transmission range. Coolant residue accumulating on the probe or receiver windows will have a detrimental effect on transmission performance. Wipe clean as often as is necessary to maintain unrestricted transmission. Operation in temperatures of 0 °C to 5 °C or 50 °C to 60 °C (32 °F to 41 °F or 122 °F to 140 °F) will result in some reduction in range.

Calibrating the OMP40-2
System installation

Probe datuming - general Often referred to as ‘calibration’ or ‘qualifying’, probe datuming involves the measurement of a calibrated feature, usually a precision ring gauge or reference sphere of precisely known diameter. Datuming software then compares the size of the ring gauge/sphere as ‘measured’ by the probe and machine tool to its calibrated size, thus calculating the ‘effective’ diameter of the stylus tip. As each spindle probe system is unique, it is imperative that you datum your probe: ? ? ? before it is used for the first time; when a new, replacement stylus is fitted; if it is suspected that the stylus has become distorted; periodically to allow for any thermal growth of the machine tool;

Probe datuming - OMP40-2 probe NOTE: Best accuracy will be achieved by minimising stylus on-centre errors during probe installation. This is necessary to allow for poor probe location in the spindle following a tool change, spindle orientation repeatability and ‘hunting’ of the spindle orientation if not mechanically clamped. Stylus ball centre to spindle centre-line relationship can be compensated for by suitable calibration of a known feature.

3.12

To relate the actual location of the workpiece surface to the machine tool’s reference frame, it is necessary to datum your OMP40-2 probe. This will allow you to: ? determine the position of the stylus ball centreline relative to the machine spindle centreline; determine the effective size of the stylus ball (electronic ball radius).

?

? ? if the repeatability of relocation of the probe shank is poor (datuming may be required each time the probe is selected); whenever the probe is moved from one machine tool to another; whenever a new shank is fitted to the probe.

?

Prior to datuming, you will need to establish the optimum length and diameter of the stylus to be used. To datum the probe:

?

1.

Perform a probe length calibration cycle in accordance with the manufacturer’s instructions supplied with your calibration software. Perform a stylus X, Y offset calibration cycle in accordance with the manufacturer’s instructions supplied with your calibration software. Perform a stylus ball calibration cycle in accordance with the manufacturer’s instructions supplied with your calibration software.

NOTE: Due to the nature of Lithium Thionyl Chloride batteries, if a 'low battery' LED sequence is ignored or overlooked, then it is possible for the following sequence of events to occur: 1. When the probe is active, the batteries discharge until battery power becomes too low for the probe to operate correctly. The probe stops functioning, but then re-activates as the batteries recharge sufficiently to provide the probe with power. The probe begins to run through the LED review sequence (see page 4.2). Again, the batteries discharge and the probe ceases to function. Again, the batteries recharge sufficiently to provide the probe with power and the sequence repeats itself.

Glossary

Kinematic switching probe A contact probe in which the kinematic seating forms an electrical circuit that is broken by the action of displacing the stylus, to provide the trigger signal. After displacement, the stylus ball returns to the highly repeatable position defined by the kinematic location points. Lobing The variation in trigger point position from a perfect spherical locus, as the direction of probing varies. Overtravel The distance travelled by the probe after the trigger point has been reached. Pre-travel The displacement from the point where the stylus ball contacts the workpiece, to the point where a probe trigger is asserted. Pre-travel variation The deviation of the pre-travel from its average value as it varies with trigger direction. This may be specified for 2D (X-Y) or 3D (X-Y-Z) measurements. Pre-travel itself is not a form of error, since it can easily be compensated for, by probe calibration. Strain gauge probe Although a strain gauge probe still uses a kinematic mechanism to retain the stylus, it does not use the resistance through the contact elements as the means to sense a trigger. Instead, a set of strain gauges are positioned on carefully designed webs within the probe structure, beyond the kinematics. These gauges measure the contact force applied to the stylus and generate a trigger. This provides a low trigger force, low pre-travel and therefore low pre-travel variation.

The closeness of agreement between the results of a measurement and the true value of the part being measured. Repeatability The variation in measurements obtained when multiple readings are taken with the same instrument and technique on the same part or item. In Renishaw terms, repeatability is the ability of a probe to trigger at the same point each time. Calibration The operation that identifies and corrects any deviation from the stated performance targets. Probe calibration Where a datum feature, of known size and position, is measured to establish the average pre-travel for the stylus concerned. Datum The reference feature from which other co-ordinates are measured. Hysteresis A systematic error arising from the difference in direction of a probing move resulting from the preceding reseat. Kinematic seating A seating mechanism in which the spatial position of a movable component is constrained in all 6 degrees of potential movement. This is achieved in a Renishaw probe by 6 contact points formed by a system of radial rollers (or ‘V’ grooves) and ball bearings.
