Multidirectional Probe (3D); Bidirectional Probe; Monodirectional Probe - Siemens SINUMERIK 840 User Manual

1 Introduction

1.3.1 Multidirectional probe (3D)

1.3.1 Multidirectional probe (3D)
With this type of probe, tool and workpiece measuring cycles can be used without restriction.
1.3.2

Bidirectional probe

This type of probe can be used on turning machines for workpiece measurement. When
performing workpiece measurement on milling machines and machining centres, this probe
type is treated as a monodirectional probe.
1.3.3

Monodirectional probe

This type cannot be used on turning machines. It can be used for workpiece measurement on
milling machines and machining centres with some few restrictions (more information is given
in the respective cycles).
It must be possible to position the spindle with the NC function "M19" and to transmit the
probe switching signal through 380° to the receiving station (on the machine column).
The probe must be aligned mechanically in the spindle in such a way that measurements can
be performed in the following directions with the spindle positioned to 0°.
X-Y plane (G17)
Z-X plane (G18)
Y-Z plane (G19)
Measurement takes longer with a monodirectional probe, because the spindle must be
positioned in the cycle several times with M19.
