Unconditional Restart of Automatic Operation
105
If in the selected plane the address of one of the axes has not been programmed (e.g., Y) and
movement has been made also in this direction, or in Z direction, the movement may be led
back to the 1
st
case, i.e., the axes will move after pressing START in neither Y, nor Z
direction.

th
case: Interrupting canned cycle in the course of positioning to R
If in the above example the movement is interrupted in the course of positioning to the
coordinate in Z direction to R=2 and manual operation is used, after returning to automatic
mode and pressing the START button the axis moves to the position in Z direction to R=2 as
in the 1
st
case.
If in the course of manual operation movements were also made in the plane X, Y after
returning to automatic mode and pressing the START button, no return in direction X, Y
occurs. This way the X, Y coordinate of the hole can be modified by the operator by means of
manual intervention even during machining.

th
case: Interrupting canned cycle in the course of hole machining
If a canned cycle has been interrupted in the
course of hole machining, by restarting with
the help of the START button it moves to
initial level in state G98 or to level R in state
G99. Afterwards it continues machining by
executing the forthcoming block. If also a
repetition count has been programmed in the
cycle and it was not the last hole machining
interrupted, after returning to initial level or
level R it continues machining by positioning
above the next hole.
Considering the above-mentioned facts there
are two ways to interrupt hole machining.
If while retracting the operator notices, that,
e.g., in case of a through hole, the pro-
grammed hole length is too short, STOP is
pressed, any of the manual modes are open-
ed and the operation is executed by means of
manual operation. After returning to auto-
matic operation and pressing the START
button the control retracts the tool and
continues the machining.
If the operator stops the drilling even before
reaching the bottom point and retracts the
tool in manual mode, than returns to auto-
matic operation, after pressing the START
button the tool moves to either initial level
or level R and the machining is continued
from there. By means of this intervention the
depth of the hole can be corrected.
