(1) The tool moves from the initial position, to the edge of clearance
Z, moving in rapid traverse along the Z axis.
(2) The tool moves, in rapid traverse along the X axis, to the position
X=0.
(3) The tool moves in cutting feedrate along the Z by P-CUT (Depth
of Cut) in –Z direction.
(4) The tool retracts by the escape amount (parameter No. 5114),
along the Z axis in +Z direction.
(5) The tool moves in cutting feedrate along the Z by P-CUT (Depth
of Cut) –escape amount in –Z direction.
(6) Steps 4 and 5 are repeated until the tool reaches the bottom of the
hole.
(7) The tool moves to the edge of clearance Z, moving in rapid
traverse along the Z axis in +Z direction..
(8) The tool return to the initial position, moving in rapid traverse
first along the X axis and the along the Z axis.
