Cycle run

Touch Probe Cycle 419 measures any coordinate in any axis
and defines it as preset. If desired, the TNC can also enter the
measured coordinate in a datum table or preset table.
1 Following the positioning logic, the TNC positions the touch
probe at rapid traverse (value from FMAX column) (see
"Executing touch probe cycles", Page 339) to the programmed
touch point 1. The TNC offsets the touch probe by the safety
clearance in the direction opposite the programmed probing
direction.
2 Then the touch probe moves to the programmed measuring
height and measures the actual position with a simple probing
movement.
3 Finally the TNC returns the touch probe to the clearance height
and processes the determined preset depending on the cycle
parameters Q303 and Q305 (see "Characteristics common to all
touch probe cycles for presetting", Page 370).

Please note while programming:

Danger of collision!
Cycles for coordinate transformation must not be active during
execution of the touch probe cycles.
Do not activate the following cycles before using touch probe
cycles: Cycle 7 DATUM SHIFT,Cycle 8 MIRROR IMAGE, Cycle
10 ROTATION,Cycle 11 SCALING and 26 AXIS-SPECIFIC
SCALING
Reset any coordinate transformations beforehand
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
If you want to save the preset of several axes in the
preset table, you can use Cycle 419 several times in a
row. However, you also have to reactivate the preset
number after every run of Cycle 419. If you work with
preset 0 as active preset, this process is not required.
