Probe Length and Radius
Probe tip radius and probe length are defined by your system installer in
AMP. These values can also be changed by using these paramacro system
parameters:
5095 Length of Probe -- used primarily for G37 operations. This distance is measured along
the axis being probed. For example, if an X-axis probing operation is being performed
(as shown in the following figure) then the value entered here is the length of the probe
on the X-axis. The length is measured from the tool gauge point to the center of the
probe radius.
5096 Radius of Probe -- used for either G31 or G37 operations. This parameter defines the
radius of the probe tip. If the documentation for your probe lists a tip diameter, enter half
of that value.
Figure 20.1 shows how these parameters are typically used.
