Addresses used in many cycles
Safety clearance G47
Safety clearances are used for approaching and departing paths. If the
cycle run takes a safety clearance into account during execution you
will find the address "G47" in the dialog. Proposed value: See (safety
clearance G47) Page 523.
Safety clearances SCI and SCK
The safety clearances SCI and SCK are considered for approach and
departure paths in drilling and milling cycles.
 SCI = Safety clearance in the working plane
 SCK = Safety clearance in infeed direction
Proposed value: See (safety clearance G147) Page 523.
Tool change point G14
With the address G14, at the end of the cycle you program a
movement of the slide to the tool change position (see "Defining the
tool change position" on page 93). You can influence the approach to
the tool change position as follows:
 No axis (do not approach the tool change position)
 0: Simultaneous (default)
 1: First X, then Z
 2: First Z, then X
 3: Only X
 4:Only Z
Cutting limit SX, SZ
With the addresses SX and SZ you limit the contour area to be
machined in the X and Z direction. Seen from the tool position at the
beginning of the cycle, the contour to be machined is truncated at
these positions.
Additive compensation Dxx
With the address Dxx you activate an additive compensation for the
entire cycle run. The xx stands for the compensation numbers 1 to 16.
The additive compensation is switched off at cycle end.
