7.3 Probing Cycles
To use the Inside/Outside Web Finding Cycle:
Place the probe in the spindle with its tool number active and the
tool type set to "Touch Probe".
Manually jog the probe stylus the approximate center in X or Y
within 0.1" (2.54 mm). If H = 1, the Z-axis should be within 0.1" (2.54
mm) above the part otherwise the Z-axis should be at the side
picking depth.
Type G145 Qn Xn Wn. If this is run from inside a program, this line
needs to be repeated for every web you wish to find or whose
position you want to reestablish.
Execute the line in Manual Data Input Mode by touching Start.
Field Code Description
DistIny B The distance from the starting point to
move in the Y-axis to find the top of the
part. The default is the current probe
position. (Optional)
X I This causes the cycle to make a protected
X move to the coordinate entered relative to
the current active work coordinate before
finding the web center. (Optional)
Y J Same as I only for the Y-axis. (Optional)
Z K Same as I only for the Z-axis. (Optional)
Offset W Work Coordinate to update with the center
location in X- or:
Y-axes. If set, work coordinate is updated.
Work coordinate register is not updated if
not set and a warning message tells the
operator no update has taken place if W is
not set. (Optional)
When positioning the probe from within the program you
should always use the G146 (Protected Probe Positioning)
cycle (see G146 instructions later in this document) or use
the I, J, or K cycle parameters for the same purpose.
