SYSTEM DESCRIPTION

The MP18 Probe is used for job set up and workpiece measurement
on CNC machine tools. Signal transmission between transmitters and
recievers is non line of sight. The radio channel is selectable and signal
transmission range is up to distances of 3m (9.8ft).

9

FEATURES

● Transmission of the probe trigger
signal using FM radio transmission
at 433MHz frequency.

● User selection of the transmission
channel (up to 69 available),
permits many systems to operate
in close proximity, with no
interference between systems.

● Switch on - switch off mode.

● Two receivers to provide cover for

signal transmission dead spots.

● M code switch on and off of the probe,
using an optional optical transmitter
module (OM16).

SYSTEM OPERATION

The probe assembly is stored in the machine
tool changer as any other tool, and is transferred
to the machine spindle for probing routines.

The probe head acts as an omni-directional switch
and is effective in the ± X, ±Y and +Z directions.

During operation, the probe stylus is driven
against a workpiece feature. On contact the radio
module probe (RMP3) transmits a probe signal to
the two radio modules machine (RMM2), using
frequency modulated (FM) radio waves.

The signal then passes via cable to the MI16
interface and onto the CNC machine control,
thereby recording the stylus contact position in
the machine tool registers. Two different contact
positions enable features to be measured.

Probing software is available from Renishaw

Radio Module Machine - transmits and receives signals
between machine control and Radio Module Probe (RMP3).

Signals received by the RMM2, pass via coaxial cable to the MI16
machine interface, which decodes and converts them into solid state
relay (SSR) outputs for use by the machine tool’s CNC controller.

An M code causes the OM16 optical transmission module, to send
probe switch on/off signal to the RPM3.

The MI16 draws 24V DC power from the CNC machine and presents
a load of up to 500mA. If this supply is not available from the machine
power can be supplied by a Renishaw PSU3 power supply unit.
