15.9 PRESET FROM INSIDE OF CORNER

(Cycle 415, DIN/ISO: G415)

Touch Probe Cycle 415 finds the intersection of two lines and

defines it as the preset. If desired, the TNC can also enter the

intersection into 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 497) to touch point

figure at upper right) that you have defined in the cycle. The

TNC offsets the touch probe by the safety clearance in the

direction opposite to the respective traverse direction.

2 Then the touch probe moves to the entered measuring height

and runs the first probing process at the probing feed rate

(column F). The probing direction is derived from the number by

which you identify the corner.

1 Then the touch probe moves to the next starting position

from there probes the second position.

2 The TNC positions the probe to starting point

starting point

to probe the third and fourth touch points.

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 528) and saves the

coordinates of the determined corner in the Q parameters listed

4 If desired, the TNC subsequently measures the preset in the

touch probe axis in a separate probing.
