Probing Parameters
Chapter 31
31-2
Function
The value entered for this parameter is the probe length used for probe
length compensation in G37’s cycles. Probe length is the distance from the
tool Gauge Point on the tool holder to the center of the probe radius, as
measured only along the axis that the probe extends.
For example, if the probe extends along the Z axis, but is mounted off
center from the tool Gauge Point, the Probe Length Compensation amount
is only the amount that it extends along the Z axis.
Axis Parameter Number
Single Process Process 1 Process 2
All [600] [20600] [21600]
Range
0.00000 to 1270.00000 mm, or
0.00000 to 50.00000 in.
This is a per process parameter. The value set here applies to all axes
assigned to that process.
Function
The value entered for this parameter is the probe radius used for probe
radius compensation in G31’s, G37’s, and G38’s cycles. Probe radius
refers to the radius of the probe tip. If the documentation for your probe
lists a tip diameter, enter half of that value here.
Axis Parameter Number
Single Process Process 1 Process 2
All [601] [20601] [21601]
Range
0.00000 to 254.00000 mm, or
0.00000 to 10.00000 in.
This is a per process parameter. The value set here applies to all axes
assigned to that process.
