Safety 1.5 Before you begin RLP40 installation guide 1.6 This page left intentionally blank RLP40 basics 2.1 Introduction Getting started Welcome to the RLP40 job set-up and inspection probe. At only 40 mm diameter, this compact probe sets industry standards for functionality, reliability and robustness in the harshest of machine tool environments. Three multicolour LEDs provide visual indication of selected probe settings. RMP40 forms part of Renishaw's family of new generation radio transmission probes, It is ideally suited to large machining centres, where line-ofsight between probe and receiver is difficult to achieve or where Z travel is limited. RLP40 complies with FCC regulations and operates in the 2.4 GHz band. It delivers interference-free transmission through the use of FHSS (Frequency Hopping Spread Spectrum). This allows many systems to operate in the same machine shop without risk of cross-interference. All RLP40 settings are configured using ‘Trigger Logic’. This technique enables the user to review and subsequently change probe settings by deflecting the stylus whilst observing the LED display. Configurable settings are: • Radio on / Radio off • Radio on / Timer off • Spin on / Spin off • Spin on / Timer off • Filter on / Filter off • Multiple probe mode on / multiple probe mode off For example: • Switch-on and switch-off methods • Probe status - triggered or seated • Battery condition Batteries are inserted or removed as shown (see ‘RLP40 batteries’ for further information). On insertion of batteries, the LEDs will begin to flash (see ‘Reviewing current probe settings’ for further information). System interface The RMI integrated interface/receiver is used to communicate between the RLP40 probe and the machine control. RLP40 installation guide RLP40 basics Trigger Logic™ 2.2 Trigger Logic™ (see Section 4, "Trigger Logic™") is a method that allows the user to view and select all available mode settings in order to customise a probe to suit a specific application. Trigger Logic™ is activated by battery insertion and subsequent stylus deflection. A sequence of stylus deflection (triggering) is then used to systematically lead the user through the available choices to allow selection of the required mode options. Current probe settings can be reviewed by simply removing the batteries for a minimum of 5 seconds, and then replacing them to activate the Trigger Logic™ review sequence. Modes of operation The RLP40 probe can be in one of three modes: Standby mode: where the probe is awaiting a switch on signal. Operational mode: activated by one of the switch on methods described on this page. In this mode the RLP40 is ready for use. Configuration mode: where Trigger Logic™ may be used to configure the following probe settings. Configurable settings Switch on/switch off methods The following switch on/switch off options are user-configurable. 1. Radio on/Radio off 2. Radio on/Timer off 3. Spin on/Spin off 4. Spin on/Timer off 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. The RLP40 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. RLP40 switch off method Switch on options are configurable Switch off options are configurable Radio on Radio off Radio switch on is commanded by machine input. Radio switch off is commanded by machine input. A timer automatically switches the probe off 90 minutes after the last trigger if it is not turned off by machine input. Timer off (timeout) Switch on time 1 second maximum Note: This assumes a good radio communication link. In a poor RF environment this may rise to a maximum of 3 seconds. Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat. Spin on Spin off Spin at 500 rev/min for 1 second minimum (6 seconds maximum). Spin at 500 rev/min for 1 second minimum (6 seconds maximum). A timer automatically switches the probe off 90 minutes after the last trigger if it is not spun. 2 seconds maximum. Note: The 2 seconds starts from the moment the spindle reaches 500 rev/min. Timer off (timeout) Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat. NOTE: After being switched on, the RLP40 must be on for 1 second minimum (the RLP40 must be spun down before it can be spun off again) before being switched off. RLP40 basics RLP40 switch on method 2.3 RLP40 installation guide RLP40 basics Multiple probe mode 2.4 The RLP40 can be configured, using Trigger Logic™, to allow multiple radio probes to be used with a single RMI. NOTES: The 'radio on' switch on method cannot be used in multiple probe mode. Multiple probe mode will not appear as an option if the 'radio on' option has been selected. RLP40 probes which are set to 'multiple probe mode on' can coexist alongside any number of RLP40 probes set to 'mode off'. To allow multiple radio probes to work in close proximity, and with a single RMI, 16 choices of 'mode on' colours are available, each representing a different machine tool installation. The colour choices available are as shown on page 4.2. The addition of any further probe(s) into a single probe installation will require that all probes are reconfigured to the same 'mode on' colour choice and that one of the probes is then repartnered with the RMI. The addition of any further probe(s), or replacements, into a multi-probe installation can be achieved simply through the reconfiguration of the probe to the same 'mode on' colour choice. Acquisition mode System set-up is achieved using Trigger Logic™ and powering on the RMI. Partnering is only required during initial system set-up. Further partnering is only required if either the RLP40 or RMI is changed. Partnering will not be lost by reconfiguration of probe settings or when changing batteries, except All probes operating with a single RMI must be set where multiple probe mode is selected. to the same 'mode on' colour choice; any multiple Partnering can take place anywhere within the probes located on adjacent machines must all be operating envelope. set to an alternative 'mode on' colour choice. Only one probe per 'mode on' colour choice needs to be partnered with the RMI as, by configuring multiple probes to a single 'mode on' colour choice, all probes using this 'mode on' colour choice will have the same identity. The probe to be partnered is partnered after selecting the 'multiple probe mode' setting and choosing the 'mode on' option. See 'Changing the probe settings' in Section 4, "Trigger Logic™". There is no limit to the number of probes that can be used with a single RMI so long as they all have the same 'mode on' colour choice. All RLP40 probes are factory set to 'mode off'. 50 (1.97) RLP40 basics RLP40 dimensions 19 (0.75) Ø40 (Ø1.57) Battery cassette 2.5 M4 stylus 12.5° 12.5° A range of probe-ready shanks is available from Renishaw RLP40 window Dimensions given in mm (in) 58.3 (2.30) 43 798 ±X M-5625-1014 ±Y Stylus overtravel limits 43 798 M-5625-1014 +Z Stylus length ±X/±Y +Z 50 (1.97) 12 (0.47) 6 (0.24) 100 (3.94) 22 (0.87) 6 (0.24) RLP40 installation guide RLP40 basics RLP40 specification 2.6 Principal application Workpiece inspection and job setup on turning centres Dimensions Length Diameter 58.3 mm (2.30 in) 40 mm (1.57 in) Weight (without shank) With batteries Without batteries 260 g (9.17 oz) 240 g (8.47 oz) Transmission type Frequency Hopping Spread Spectrum (FHSS) radio Radio frequency 2400 MHz to 2483.5 MHz Switch ON methods Radio 'M' code, spin Switch OFF methods Radio 'M' code, spin, time out Spindle speed (maximum) 1000 rev/min Operating range Up to 15 m (49.2 ft) Receiver/interface RMI combined antenna, interface and receiver unit Sense directions Omni-directional ±X, ±Y, +Z Uni-directional repeatability maximum 2σ value in any direction 1.0 µm (0.00004 in) is certified at 480 mm/min (1.57 ft/min) using a 50 mm (1.97 in) long stylus.

The stylus trigger force is the force exerted on the component when the probe triggers. However, the maximum force applied to the component will occur after the trigger point and will be greater than the trigger force. The magnitude depends on a number of factors affecting probe overtravel including measuring speed and machine deceleration. If the forces applied to the component are critical, contact Renishaw for further information.

This allows easy installation, either inside or outside the machine enclosure. Coolant and swarf residue accumulating on the RLP40 and RMI may have a detrimental effect on transmission performance. Wipe clean as often as is necessary to maintain unrestricted transmission. Stylus When operating, do not touch either the RMI cover or the probe glass window with your hand, as this will affect the performance. Some reduction in range may result when operating in temperatures of 0 °C to 5 °C (32 °F to 41 °F) and 50 °C to 60 °C (122 °F to 140 °F). RLP40 installation guide System installation Performance envelope when using the RLP40 with the RMI 3.2 NOTE: RLP40 / RMI installation with RLP40 in radio-on configuration. RLP40 has a built-in hibernate mode (battery saving mode) that saves battery life when the RMI is unpowered in radio-on (radio-off or time-off) configurations. The RLP40 goes into hibernate mode 30 seconds after the RMI is unpowered (or the RLP40 is out of range). When in hibernate mode, the RLP40 checks for a powered RMI every 30 seconds. If found, the RLP40 goes from hibernate mode to stand-by mode, ready for radio‑on. RLP40 / RMI positioning The probe system should be positioned so that the optimum range can be achieved over the full travel of the machine's axes. 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 performance envelope shown below. To assist in finding the optimum position of the RMI, the signal quality is displayed on an RMI signal LED. Performance envelope The RLP40 and RMI must be within each other's performance envelope as shown below. The performance envelope shows line-of-sight performance, however radio transmission does not require this providing a reflected path (of less than 15 m (49.2 ft)) is available. 15 (49) Range metres (feet) OPERATING AND SWITCH ON/OFF 75° 60° 10 (33) 45° 75° 60° 5 (16) 30° 10 (33) 30° 15° (16) 15° 0° RLP40 M-5625-1014 15° 60° 45° 30° 15° 0° 75° 15 (49) 45° RMI 5 (16) 90° 0° 10 (33) 30° 15 (49) 75° 15° 15° 45° 60° 30° 30° 45° 45° 60° 60° 75° 90° 75° Preparing the RLP40 for use System installation Fitting the stylus 3.3 M-5000-3707 RLP40 installation guide System installation Installing the batteries NOTES: See Section 5 - Maintenance for list of suitable battery types. When inserting batteries, check that the battery polarity is correct. 3.4 If dead batteries are inadvertently inserted into the probe then the LEDs will remain a constant red, see page 4.4. Do not allow coolant or debris to enter the battery compartment. After inserting the batteries the LEDs will display the current probe settings (for details see Section 4 - Trigger Logic™). Please remove battery isolation device from the battery compartment, before use. 1 System installation Mounting the probe on a shank 3.5 2 mm AF 0.5 Nm - 1.5 Nm (0.37 lbf.ft - 1.1 lbf.ft) (x 2) RLP40 installation guide System installation Stylus on-centre adjustment 3.6 NOTES: If a probe and shank assembly is dropped, it must be rechecked for correct on-centre adjustment. Do not hit or tap the probe to achieve on-centre adjustment. 2 mm AF 0.5 Nm - 1.5 Nm (0.37 lbf.ft - 1.1 lbf.ft) (x4) 2 mm AF 1.5 Nm - 2.2 Nm (1.1 lbf.ft - 1.62 lbf.ft) (x2) 2 mm AF 1.5 Nm - 2.2 Nm (1.1 lbf.ft - 1.62 lbf.ft) (x4 ) 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 trigger force in special circumstances e.g. where there is excessive machine vibration or insufficient force to support the stylus weight. To adjust the trigger force, turn the adjusting screw anticlockwise (as shown) to reduce the force (more sensitive); eventually it reaches a stop. Turn the adjusting screw clockwise (as shown) to increase the force (less sensitive). If the internal screw becomes disengaged, remove any pressure on the stylus and turn the key anticlockwise to re-engage the thread. Trigger forces in the XY plane vary around the stylus and depend on trigger direction. Stylus trigger force adjustment and use of styli other than test stylus types may cause probe repeatability to differ from the calibration certificate results.

They are: Why calibrate a probe? • calibrating either in a bored hole or on a turned diameter of known size; • calibrating either in a ring gauge or on a datum sphere; • calibrating the probe length. A spindle probe is just one component of the measurement system which communicates with the machine tool. Each part of the system can introduce a constant difference between the position that the stylus touches and the position that is reported to the machine. If the probe is not calibrated, this difference will appear as an inaccuracy in the measurement. Calibration of the probe allows the probing software to compensate for this difference. Calibrating in a bored hole or on a turned diameter • when a probe system is to be used for the first time; • when a new stylus is fitted to the probe; Calibrating a probe, either in a bored hole or on a turned diameter of known size, automatically stores offset values between actual and theoretical stylus ball position and also the electronic ball radius of the stylus of the stylus being used. The stored values are then used automatically in the measuring cycles. Measured values are compensated by these offsets so that positional and size measurements relative to spindle centre line are accurate. • when it is suspected that the stylus has become distorted or that the probe has been crashed; Calibrating in a ring gauge or on a datum sphere • at regular intervals to compensate for mechanical changes of your machine tool; • if repeatability of relocation of the probe shank in the machine spindle is poor. In this case, the probe may need to be recalibrated each time it is selected. During normal use, the difference between the touch position and the reported position does not change, but it is important that the probe is calibrated in the following circumstances: It is good practice to set the tip of the stylus oncentre, because this reduces the effect of any variation in spindle and tool orientation (see page 3.6). A small amount of run-out is acceptable, and can be compensated for as part of the normal calibration process. Calibrating a probe either in a ring gauge or on a datum sphere with a known diameter automatically stores one or more value for the radius of the stylus ball. The stored values are then used automatically by the measuring cycles to give the true size of the feature. The values are also used to give true positions of single surface features. NOTE: The stored radius values are based on the true electronic trigger points. These values are different from the physical sizes. Calibrating the probe length Calibrating a probe on a known reference surface automatically stores the position of the stylus ball (probe length or geometry offset) relative to either a turret or workpiece reference face.

RLP40 installation guide Trigger Logic™ RLP40 – RMI partnership 4.6 System set-up is achieved using Trigger Logic™ and powering the RMI. Partnering is only required during initial system set-up. Further partnering is only required if either the RLP40 or RMI is changed, or a system is reconfigured for multiple probes (multiple probe mode). Partnering will not be lost by reconfiguring the probe settings or when changing batteries, except where multiple probe mode is selected. Partnering can take place anywhere within the operating envelope. In configuration mode, configure the probe settings as required until you reach the "Acquisition mode" menu.

When the probe is active, the batteries discharge until battery power becomes too low for the probe to operate correctly. 2. The probe stops functioning, but then reactivates as the batteries recover sufficiently to provide the probe with power. 3. The probe begins to run through the LED review sequence (see page 4.1). 4. Again, the batteries discharge and the probe ceases to function. 5. Again, the batteries recover sufficiently to provide the probe with power, and the sequence is repeated. 4.7 Trigger Logic™ RLP40 installation guide 4.8 This page left intentionally blank Maintenance 5.1 Maintenance Cleaning the probe You may undertake the maintenance routines described in these instructions. Wipe the window of the probe with a clean cloth to remove machining residue. This should be done on a regular basis to maintain optimum transmission. Further dismantling and repair of Renishaw equipment is a highly specialised operation, which must be carried out at authorised Renishaw Service Centres. Equipment requiring repair, overhaul or attention under warranty should be returned to your supplier. RLP40 installation guide Maintenance Changing the batteries CAUTIONS: Do not leave exhausted batteries in probe. When changing batteries, do not allow coolant or debris to enter the battery compartment. 5.2 When changing batteries, check that the battery polarity is correct. Take care to avoid damaging the battery cassette gasket. Only use specified batteries (page 5.3). CAUTIONS: Please dispose of exhausted batteries in accordance with local regulations. Never dispose of batteries in a fire. NOTES: After removing the old batteries, wait more than 5 seconds before inserting the new batteries. 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 cassette gasket and mating surfaces are clean and free from dirt before reassembly. If dead batteries are inadvertently inserted into the probe, the LEDs will remain a constant red.
