along the X axis and then along the Z.
(2) If pecking is specified then the tool moves in cutting feedrate in
-X axis direction by the cut amount . If pecking is not specified
then the tool moves in cutting feedrate in -X axis direction until
the bottom of the groove.

(5) From the bottom of the groove the tool moves in rapid traverse
first in –X direction up to the edge of the clearance and then in
–Z direction by the tool width cut amount.
(6) The steps 2 to 5 are iteratively repeated until position P2 is
reached.
(7) The tool moves to the right hand side of the groove next to the
center of the groove itself, at the edge of the clearance, moving in
rapid traverse first along the X axis.
(8) The steps 2 to 4 are iteratively repeated until the tool reaches the

(9) From the bottom of the groove the tool moves in rapid traverse
first in –X direction up to the edge of the clearance and then in
+Z direction by the tool width cut amount.
(10) The steps 8 and 9 are iteratively repeated until position P1 is
reached.
(11) The tool return to the initial position moving first along X and
