7.3 Probing Cycles
Protected Probe Positioning
 When an X, Y, and/or Z move is programmed using the Protected
Positioning Cycle, the control stops the axis travel and program and
alarm, if the probe stylus is triggered before reaching the target set
in the X, Y, and/or Z parameters.
 This cycle is intended to offer some degree of safety when moving
the probe around the part; however, it is not fool proof and does not
protect against gross bad programming where the probe body
would encounter an obstruction before the probe stylus is triggered.
Extreme care should be taken to avoid this condition as probe
damage may result.
 Calibrate the work probe at least once before trying to use this cycle.
 A preliminary tool-length offset must be set by eye for the work
probe. The tool offset, and work coordinate must be active before
using this cycle in a program. See Section 4, "Tool-Length Offsets"
on page 73.
 The Protected Probe Positioning Cycle can be run from within a
program or from the Manual Data Input Mode.
To use the Protected Probe Positioning Cycle:
 Place the probe in the spindle and make sure that its tool and work
coordinate offsets are active and the tool type set to "Touch Probe".
 Type G146 Xn Yn Zn Fn. If this is run from inside a program, this line
needs to be repeated for every move you wish to make.
 Execute the line in Manual Data Input Mode by touching Start
Field Code Description
X X X Target position relative to current active
work coordinate.
Y Y Y Target position relative to current active
work coordinate.
Z Z Z Target position relative to current active
work coordinate combined with the current
active tool-length offset.
Feed F Feedrate at which to travel to target. F is
only active for the current move so it must
be restated every time or the default takes
precedence. The default is set in the
machine setup parameter
positioningFeedrate_Normally.
