Probe contact
July 2013
In MP6531.x, enter the diameter (disk) or the edge length (cube) for the
probe contact.
In MP6580.x, MP6581.x and MP6582.x, enter the coordinates of the probe
contact center with respect to the machine datum. After calibration, the NC
internally stores the exact center of the probe contact.
If a PLC datum shift should be included in the tool measurement, set
MP6500 bit 12 = 1.
For a cube it suffices to probe from one direction:
Set MP6500 bit 8 = 1.
With MP6500 bit 9, specify whether the basic rotation of the cube is
measured automatically or whether it should be aligned to the axes
mechanically. During automatic measurement, the edge of the touch probe
is probed twice and the basic rotation is calculated. All subsequent probing
is done automatically at a right angle to the touch probe edge.
With MP6500 bit 10, select how to pre-position to the starting point. If bit
10 = 1, bit 9 must equal 0.
MP6500
Tool measurement with TT table touch probe
Format:
%xxxxxxxxxxxxx
Input:
Bit 7 – Reserved
Bit 8 – Probing routine
0: Probe contact is probed from several directions
1: Probe contact is probed from one direction
Bit 9 – Automatic measurement of the direction of the probe
contact basic rotation (bit 8 = 1)
0: Basic rotation is not measured
1: Basic rotation of the probe element is automatically
measured
Bit 10 – Probing routine (bit 8 = 1)
0: Pre-positioning to starting point in all three principal axes
1: Pre-positioning to starting point in the tool axis and in the axis
of the probing direction (MP6505) (bit 9 = 0)
Bit 12 – Inclusion of the PLC datum shift
0: Do not include the PLC datum shift
1: Include the PLC datum shift
