Preliminary information

A workpiece set-up and inspection probe is, in

effect, another tool in the system. A probe cycle

may be included at any stage of the machining

process.

Signals are transmitted between the probe and

the machine’s control, via the OMI or alternatively

the OMM + MI 12. Interface units convert probe

signals into an acceptable form for the machine’s

control.

MI 12

Twin OMM mounting

On large machine tools it is possible to provide

greater reception coverage by mounting two

OMMs connected to a single MI 12.

Remote indicator

The MI 12 interface contains an LED and acoustic

indicator. When the probe is triggered the LED

will change state and a beep is emitted.

If the MI 12 is hidden from the operator, a remote

lamp or bleeper may be placed in a position where

it is easily seen or heard.
