3. Taps down to point Z at the bottom of the hole in G01;
4. Drill CW after P;
5. Retracts to point R in G01;
6. Drill CCW after P;
7. Retracts to the initial point (G98) or point R (G99) in G00.
Programming Example:
F1200. S600
G90
G00 X0. Y0. Z10. ’moving to the initial point.
G17
M04 ’drill CCW on
G90 G99
’Setting the coordinates of point R, point Z and hole 1, with dwell as 2s and drilling speed as 800
G74 X5. Y5. Z-10. R-5. P2000. F800
X25. ’hole 2
Y25. ’hole 3
G98 X5. ’hole 4, and setting to return to the initial point.
X10. Y10. Z-20. ’hole 5, and setting a new point Z as -20
G80
M05 ’drill stop
M02
G76 Fine Boring Cycle
This command is not supported at the moment.
Command Format: G76 X_Y_Z_R_Q_P_F_K_;
Description:
X_Y_: hole position data (absolute/incremental coordinate)
Z_: the position of point Z at the bottom of the hole (absolute programming); the distance from
point R to point Z at the bottom of the hole (incremental programming)
R_: the position of point R (absolute programming); the distance from the initial point to point R
(incremental programming)
Q_: displacement of the tool at the bottom of the hole (incremental and positive, and minus sign
will be ignored)
P_: the dwell time of tool at the bottom of the hole, in ms, with no decimal point
F_: feed speed, even if the canned cycle is cancelled, this modal data is still effective in the
subsequent machining.
K_: number of repeats (repeated movement and drilling, effective under G91 incremental mode)
