Touch Probe Cycles: Automatic Presetting | SLOT CENTER PRESET (Cycle 408, DIN/ISO: G408)

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

Reset any coordinate transformations beforehand

Danger of collision!

To prevent a collision between touch probe and workpiece, enter

estimate for the slot width. If the slot width and the safety

clearance do not permit pre-positioning in the proximity of the

touch points, the TNC always starts probing from the center

of the slot. In this case the touch probe does not return to the

clearance height between the two measuring points.

Before a cycle definition you must have programmed a tool

call to define the touch probe axis.
