RMP400 basics

2.1

Introduction

The RMP400 offers an unrivalled combination of size, accuracy, reliability and robustness and, allows high-accuracy probing on small to medium machining centres or other machines where line-of-sight problems affect optical signal transmission.

Successfully combining patented RENGAGE™ strain gauge technology with the patented frequency hopping radio transmission system of the RMP40, the RMP400 provides existing probe users with a simple upgrade to solid-state strain gauge technology and all the associated benefits this brings:

• excellent 3D performance to allow probing of

contoured surfaces;

• improved repeatability in all probing directions;

• a low triggering force combined with low pre-

travel variation to provide high accuracy, even when used with long styli;

Performing this calibration for every 3D direction can be time-consuming.

The RMP400 has almost no pre-travel variation, so a single calibration value may be used for any probing angle in 2D or 3D. This results in a vastly reduced calibration time. An additional benefit is a corresponding reduction in errors introduced by environmental changes within the machine during a long calibration cycle.

• The ability to be used in applications

where axial and radial reorientations are used, enabled by the use of solid state accelerometers:

The auto-reset function is required and recommendations should be followed for optimum metrology performance.

Getting started

Three multicolour probe LEDs provide visual indication of selected probe settings.

• a proven ten-fold improvement in life (10 million

triggers); ????

• the elimination of reseat failures;

• high resistance to machine tool vibration;

• resistance to shock and false triggering

through the use of solid state accelerometers.

In addition to providing high-accuracy measurement on your machine tool, the RMP400 also offers:

• Faster calibration:

On complex 3D parts, it is common to measure in several different directions. Each direction of a standard mechanical probe must be calibrated, to ensure that the pre-travel variation is compensated in the measurement.

For example:

• Switch-on and switch-off methods

• Probe status – triggered or seated

• Battery condition

Batteries are inserted or removed as shown (see page 3.5, “Installing the batteries”) for further information).

On insertion of batteries, the LEDs will begin to flash (see page 4.1, “Reviewing the probe settings”).

Page 12

System interface

Draft 5 16/04/18

Configurable settings

The RMI and RMI-Q are integrated interfaces/ receivers used to communicate between the RMP400 probe and the machine control.

RMP400 basics

2.2

Trigger Logic™

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 uses a sequence of stylus deflections (triggering) to systematically lead the user through the available choices to allow selection of the required mode options.

A Trigger Logic app is available that simplifies this process with clear, interactive instructions and informative videos and is available for download on the following app stores.

Switch-on/switch-off methods

The following switch-on/switch-off options are user-configurable.

• Radio on/Radio off

• Radio on/Timer off

• Spin on/Spin off

• Spin on/Timer off

Current probe settings can be reviewed by simply removing the batteries for a minimum of

seconds, and then replacing them to activate

five

the Trigger Logic review sequence.

obe modes

The RMP400 probe can be in one of three modes:

Standb

signal.

NOTE: The RMP400 will enter hibernation mode should the system interface be powered off or out of range for a period of 30 seconds (only applicable to “radio on” mode).

y mode – Probe is waiting for a switch-on

Operational mode – When activated by one of

the switch-on methods, the probe is switched on and ready for use.

Configuration mode – Ready to change the probe settings using Trigger Logic.

Switch-on options are configurable

RMP400 switch-off method

Switch-off options are configurable

Probe ready time

Radio on

Radio switch on is commanded by machine input.

Spin on

Spin at 500 rev/min for one second minimum.

Radio off

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)

Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat.

Spin off

Spin at 500 rev/min for one second minimum. A timer automatically switches the probe off 90 minutes after the last trigger if it is not spun.

Timer off (timeout)

Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat.

1.7 seconds maximum.

RMP400 basics

2.3

2.5 seconds. (The probe must be stationary for 2.5 seconds minimum after it has stopped spinning.)

NOTES:

In “radio on” mode, the switch-on time is user selectable “fast” or “standard” when using RMI-Q (selection is made in RMI-Q). Otherwise

1.7 seconds.

For more information on the user selectable switch-on time when operating with RMI-Q, please refer to the installation guide RMI-Q radio machine interface (Renishaw part no. H-5687-8504).

In “radio on” mode, the switch-on time assumes a good radio communication link. In a poor RF environment this may rise to a maximum of

3.0 seconds.

In “spin on” mode, the one second starts from the moment the spindle reaches 500 rev/min.

The RMP400 must be on for a minimum of one second before being switched off.

Page 14

RMP400 installation guide

Draft 5 16/04/18

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.

RMP400 basics

2.4

When the filter is enabled, a constant 8 ms or 16 ms delay is introduced to the probe’s output. The factory setting is 8 ms. If false triggering is noticed, then consider increasing the filter delay to 16 ms.

Auto-reset function

In previous strain gauge products, the probe was required to be turned off during reorientation moves. The auto-reset function in the RMP400 can compensate for stylus forces, resulting from changes in probe orientation, that can cause the probe to trigger.

This feature is controlled by solid state accelerometers and is suitable for applications where axial and radial reorientation of the probe is applied.

To achieve optimum metrology performance when the auto-reset function is turned on, a dwell is recommended before making a programmed move that follows any reorientation of the probe.

When using a stylus of up to 150 mm long, a 0.2 second dwell is necessary. In most applications the machine response time will adequately provide this.

Up to four RMP400s can be used with a single RMI-Q in “radio on/radio off” mode. For further details of this functionality, please refer to the installation guide RMI-Q radio machine interface (Renishaw part no. H-5687-8504).

NOTES:

Multiple probe mode is a function of the RMP400, as such, the option will not appear when the “radio on” option has been selected.

RMP400 probes which are set to “multiple probe mode on” can coexist alongside any number of RMP400 probes set to “multiple probe mode off”.

To allow multiple radio probes to work in close proximity, and with a single RMI or RMI-Q, 16 choices of “mode on” colours are available, each representing a different machine tool installation. (see page 4.2, “Multiple probe settings”).

All probes operating with a single RMI or RMI-Q must be set to the same “mode on” colour choice; any multiple probes located on adjacent machines must all be set to an alternative “mode on” colour choice.

NOTE: Each probe per “mode on” colour choice needs to be partnered with the RMI or RMI-Q. By conﬁguring multiple probes to a single “mode on” colour choice, all probes using this “mode on” colour choice will have the same identity.

When using a heavy stylus configuration, or a stylus longer than 150 mm, it is recommended that the RMP400 should be turned off during reorientation moves.

Multiple probe mode

The RMP400 can be configured, using Trigger Logic, to allow multiple radio probes in “spin on/ spin off” or “shank on/shank off” to be used with a single RMI or RMI-Q.

The probe to be partnered is partnered after selecting the multiple probe mode setting and choosing the “mode on” option. (see page 4.4, “Changing the probe settings”).

There is no limit to the number of probes that can be used with a single RMI or RMI-Q so long as they all have the same “mode on” colour choice. All RMP400 probes are factory set to “mode off”.

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 or RMI-Q.

Page 15

The addition of any further probe(s), or

Draft 5 16/04/18

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 or RMI-Q.

Partnering is only required during initial system set-up. Further partnering is only required if either the RMP400 or RMI/RMI-Q is changed.

NOTES:

Systems using the RMI-Q can be partnered with up to four RMP400s manually. Alternatively this can be achieved by using ReniKey; a Renishaw machine macro cycle which does not require the RMI-Q to be power cycled.

RMP400 basics

2.5

For more information or to download ReniKey free of charge visit:

www.renishaw.com/mtpsupport/renikey

Partnering by ReniKey is not available for RMI.

Partnering will not be lost by reconfiguration of probe settings or when changing batteries, except where multiple probe mode is selected.

Partnering can take place anywhere within the operating envelope.

The featured range of solid carbon fibre styli ensure the best possible performance of the RMP400.

It is possible that the featured range of solid carbon fibre styli may not be suitable for every RMP400 application and that it may be necessary to select specialised styli configurations to meet specific application requirements.

In applications where specialised styli are to be used, it may be beneficial to reduce the speed of probing moves. It has been seen in some cases that specialist styli configurations do not exhibit the probing characteristics and performance that would have otherwise been expected and achieved when using standard styli. Reducing the speed of the probing move may, in some cases, improve the performance of the probe.

A-5003-6510 Carbon fibre

When selecting components for an application specific stylus, it is recommended that a configuration with the least number of components is chosen. The stylus diameter should always be as large as possible and the overall stylus length kept to a minimum. If a stem with a reduced diameter is required, then it is recommended that an M4 stem with a short length and reduced diameter is selected.

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 or RMI-Q 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 or RMI-Q, the signal quality is displayed on an RMI or RMI-Q signal LED.

The RMP400 has a built-in hibernation mode (battery-saving mode) that saves battery life when the RMI or RMI-Q is unpowered in radio-on (radio-off or timer-off) conﬁgurations. The RMP400 goes into hibernation mode 30 seconds after the RMI or RMI-Q is unpowered (or the RMP400 is out of range). When in hibernation mode, the RMP400 checks for a powered RMI or RMI-Q every 30 seconds. If found, the RMP400 goes from hibernation mode to standby mode, ready for radio-on.

Performance envelope

The RMP400 and RMI or RMI-Q must be within each other’s performance envelope, as shown below. The performance envelope shows line-ofsight performance, however, this is not necessary for the RMP400 radio transmission as it will operate with any reflected radio path provided that the reflected path length does not exceed the 15 m (49.2 ft) operating range.

Calibrating the RMP400

Draft 5 16/04/18

Why calibrate a probe?

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

Calibrating a probe, either in a bored hole or on a turned diameter of known size, automatically stores values for the offset of the stylus ball to the spindle centre line. The stored values are then used automatically in the measuring cycles. Measured values are compensated by these values so that they are relative to the true spindle centre line.

Calibrating in a ring gauge or on a datum sphere

System

3.7

installation

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:

• when a probe system is to be used for the first

time;

• when the enhanced trigger filter delay is

changed;

• when a new stylus is fitted to the probe;

• when it is suspected that the stylus has

become distorted or that the probe has been crashed;

• at regular intervals to compensate for

mechanical changes of your machine tool;

• if repeatability of relocation of the probe shank

is poor. In this case, the probe may need to be recalibrated each time it is selected.

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, “Stylus on-centre adjustment”). 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 determines the length of the probe, based on the electronic trigger point. The stored value for length is different from the physical length of the probe assembly. Additionally, the operation can automatically compensate for machine and fixture height errors by adjusting the probe length value that is stored.

Three different operations are to be used when calibrating a probe. They are:

• calibrating either in a bored hole or on a turned

diameter of known position;

• calibrating either in a ring gauge or on a datum

sphere;

• calibrating the probe length.

Master reset function

RMP400 features a master reset function to assist user’s who have mistakenly changed the probe settings into an unintended state.

The application of the master reset function will clear all current probe settings and return the probe to default settings.

The default settings are as follows:

• Radio switch-on

• Radio switch-off

• Auto-reset on, Enhanced trigger filter on 8 ms

• Hibernation mode on 30 s

• Multiple probe mode off

The default settings may not be representative of the required probe settings. Further configuration of RMP400 may subsequently be necessary to achieve the required probe settings.

To reset the probe

1. First enter into the Trigger Logic™ menu and ensure that the stylus is no longer deflected.

2. From within the Trigger Logic menu, hold the stylus deflected for 20 seconds. After this the status LEDs will proceed to flash yellow eight times. A confirmation for master reset is required, if nothing is done the probe will timeout.

To confirm that a master reset is required, release the stylus and then hold the stylus deflected again until the eight yellow flash sequence has ended. This action will clear all probe settings and return the probe to default settings. Following an LED check the RMP400 will then go back into Trigger Logic and will display “Switch-on method”.

3. Further configuration using Trigger Logic may be necessary to achieve the required probe settings.

1. Probe is in the Trigger Logic menu. Ensure that the stylus is no longer deflected.
