10.1.5 Programming order
Preparatory (G), technological (F, S) and auxiliary (M, H) functions
must be defined before defining the canned cycle.
Functions G98, G99 and the positioning move to the machining point
must also be programmed before.
Example:
Blocks N10 (movement) and N11 (canned cycle definition) can also
be defined as a single block being the canned cycle definition at the
end.
When defining a new canned cycle inside the influence zone of
another active cycle, use the following methods:
In the example on the left, block N20 must be programmed to cancel
the active canned cycle. Otherwise, block N30 will execute the active
cycle defined in N10.
T1 D1 M6
Selects tool 1 and offset 1.
G0 G90 X0 Y0 Z25
It moves the tool, in rapid, to X0 Y0 Z25.
N10 G99 G1 X60 I30 F1000 S2000 M4
Moves in G1 to the machining point X60 Y0.
The starting plane will be Z25.
The machining will have a withdrawal to the reference plane (G99).
N11 G81 Z2 I-20
Drill in X60 Y0.
Withdraw to Z2, reference plane (G98 active).
Maintains the conditions prior to the cycle (G1 F1000 S2000 M4).
G98 G2 X160 I50
Circular interpolation (G2) to X160 Y0 Z25.
Drilled at that point.
Withdraw to the starting plane (Z25).
