Touch Probe Cycles: Automatic Presetting | PRESET FROM INSIDE OF RECTANGLE (Cycle 410,

DIN/ISO: G410)

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

estimates for the lengths of the first and second sides. If

the dimensions of the pocket 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 pocket. In this

case the touch probe does not return to the clearance height

between the four measuring points.

Before a cycle definition you must have programmed a tool

call to define the touch probe axis.
