Touch Probe Cycles: Automatic Presetting | PRESET FROM OUTSIDE OF CORNER (Cycle 414, DIN/ISO: G414)

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.
The TNC always measures the first line in the direction
of the minor axis of the working plane.
By defining the positions of the measuring points
3 you also determine the corner at which the TNC sets
the preset (see figure at right and table below).
Corner X coordinate
A Point 1 greater than
point 3
B Point 1 less than point
C Point 1 less than point
D Point 1 greater than
point 3
