5238-E P-164
SECTION 7 FIXED CYCLES
The deep-hole drilling cycle is executed in the peck feed mode.
In the program shown above, peck feed in 10 mm increments (diameter value) is repeated until the
programmed depth is reached, where dwell motion is executed for one second.

D word : peck feed stroke (mm)
E word
: duration of dwell motion (seconds)
•
Tool rotation, and C-axis clamp and unclamp commands in block N103 through N108 need not
be designated as they are generated automatically.
•
In block N102, which calls out drilling cycle on the second hole, program only the commands
differing from those specified in the previous block N103. In blocks N105 and N106, the same
programming concept applies.
•
S, M, and T codes must not be programmed during fixed cycle mode operation.
•
The value D of the peck feed stroke is specified in absolute value and is always preceded by a
plus sign.
•
The peck feed stroke D command is effective for deep-hole drilling cycle. The duration, E, of
dwell motion is effective for deep-hole drilling, boring, and reaming cycles.
