MILLING CANNED CYCLES.
Preparatory (G), technological (F, S) and auxiliary (M, H) functions must be defined before the canned cycle.
Functions G98, G99 and the positioning move to the machining point must also be programmed before.
• G80: Canned cycle cancellation.
• G98: Withdrawal to the starting plane.
• G99: Withdrawal to the reference plane.
G81. Drilling canned cycle
G81 Z I K
Z
Reference plane.
I
Drilling depth.
K
Delay, in seconds, between the drilling and the
withdrawal movement.
G82. Drilling canned cycle with variable peck
G82 Z I D B H C J K R L
Z
Reference plane.
I
Drilling depth.
D
Distance between the reference plane and the part
surface.
B
Drilling peck (step).
H
Distance or coordinate it returns to, in rapid (G00),
after each drilling step.
C
Approach coordinate.
J
It defines after how many drilling pecks the tool
returns in rapid (G00) to the reference plane (Z).
K
Dwell, in seconds, at the bottom of the hole.
R
Factor that increases or reduces the drilling peck
(step) "B".
L
