RMP60basics

Draft copy 09/07/12

2.12.1

Introduction

RMP60 is part of a new generation of radio
transmission part probing systems, ideally suited
to large machining centres or where line-of-sight
between probe and receiver is difficult to achieve.

RMP60 features an integrated probe module
delivering exceptional robustness and generous
overtravel.

RMP60 complies with worldwide standards
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-talk.

RMP60 can be operated/used alone or form part
of a larger system comprised of multiple radio
spindle probes and/or tool setters to function with
a single interface.

All RMP60 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.

Gettingstarted

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

For example:

• Switch-on and switch-off methods

• Probe status - triggered or seated

• Battery condition

Batteries are inserted or removed as shown (see
‘Installing the 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 or RMI-Q are integrated interfaces/
receivers used to communicate between the
RMP60 probe and the machine control.

Configurable settings are:

• Switch-on/switch-off method

• Trigger filter setting

• Hibernation setting

• Multiple probe mode

RMP60 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 deflection (triggering) 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 RMP60 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 RMP60 is ready for use.

Configuration mode: where Trigger Logic™ may
be used to configure the following probe settings.

Hibernation mode: ??????

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 1 second
minimum. A timer automatically
switches the probe off 90 minutes
after the last trigger if it is not spun.

NOTES:

In ‘radio on’ mode, the switch on time is user
selectable 0.5 or 1.0 second maximum when
using RMI-Q (selection is made in RMI-Q).
Otherwise 1.0 second maximum.

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.

For more information on the user selectable switch
on time when operating with RMI-Q, please refer
to the RMI-Q installation guide.

In 'spin on mode , the 2 seconds starts from the
moment the spindle reaches 500 rev/min.

After being switched on, the RMP60 must be on
for 1 second minimum before being switched off.

1 second maximum.

RMP60 installation guide

Draft copy 09/07/12

RMP60 basics

2.4

Enhanced trigger filter

Probes subjected to high levels of vibration or
shock loads may output probe trigger signals
without having contacted any surface. The
enhanced trigger filter improves the probe’s
resistance to these effects.

When the filter is enabled, a constant nominal 10
or 20 ms delay is introduced to the probe output.

It may be necessary to reduce the probe
approach speed to allow for the increased stylus
overtravel during the extended time delay.

Factory set to OFF.

Hibernation mode

Only applicable to ‘radio-on’ mode.

When RMP60 is in standby and RMI or RMI-Q
is powered off or out of range, the probe enters
hibernation; a low power mode designed to save
battery life. The probe ‘wakes’ from hibernation to
periodically check for it’s partnered RMI or RMI-Q.

The 'wake-up frequency can be set to 30 seconds,
5 seconds or set to off; the probe never goes into
hibernation.

Factory set to 30 seconds.

Multiple probe mode

The RMP60 can be configured, using Trigger
Logic™, to allow multiple radio probes in ‘spin on/
off’ or ‘shank on/off’ to be used with a single RMI
or RMI-Q.

Up to four RMP60s can be used with a single
RMI-Q in ‘radio on/off’ mode. For further details
of this functionality, please refer to the RMI-Q
installation guide.

NOTES:

Multiple probe mode is a function of the RMP60,
as such, the option will not appear when the 'radio
on' option has been selected.

RMP60 probes which are set to 'multiple probe
mode on' can coexist alongside any number of
RMP60 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 'Multiple probe settings' in Section 4 -
Trigger Logic™.

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. Only one probe per 'mode on' colour
choice needs to be partnered with the RMI or
RMI-Q 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 or RMI-Q so long as
they all have the same 'mode on' colour choice. All
RMP60 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 are then repartnered
with the RMI or RMI-Q.

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

Draft copy 09/07/12

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 RMP60 or RMI/RMI-Q is changed.

NOTES:

Systems using the RMI-Q can be partnered with
up to four RMP60s manually. Alternatively this
can be achieved by using ReniKey; a Renishaw
machine macro cycle which does not require the
RMI-Q to be powered cycled.

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 .

RMP60 basics

Partnering can take place anywhere within the
operating envelope.

Note 2 Trigger force, which is critical in some applications, is the force exerted on the component by the stylus

when the probe triggers.
The maximum force applied will occur after the trigger point i.e. overtravel. The force value depends on
related variables including measuring speed and machine deceleration.

and machine tool windows. This allows easy
installation, either inside or outside the machine
enclosure.

Stylus trigger force and
adjustment

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 to reduce the force (more
sensitive) or clockwise to increase the force (less
sensitive). A stop helps to prevent damage which
could be caused by overtightening the adjusting
screw.

Calibrating the RMP60

Draft copy 09/07/12

• calibrating either in a bored hole or on a
turned diameter of known position;

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.

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
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
on-centre, because this reduces the effect of
any variation in spindle and tool orientation (see
'Stylus on-centre adjustment' in Section 3 -
System Installation). A small amount of run-out
is acceptable, and can be compensated for as
part of the normal calibration process.

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

• calibrating either in a ring gauge or on a
datum sphere;

• calibrating the probe length.

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

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.

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.

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 'Reviewing the
current probe settings' in Section 4 - Trigger
Logic™).

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.
