6.27.3. G76. Automatic block generation
This feature is only available on the TS model.
This function is used to generate blocks that are automatically loaded into the CNC or to
a computer (via DNC). If the new program is going to be loaded into the CNC, a block of
the type G76 P5 must be previously written.
But if the new program is to be sent directly to a computer a block of the type G76 N5 must
be previously written.
Once G76 P5 or G76 N5 executed; each time that the CNC executes any block containing
G76, it will load whatever is after G76 into the new program.
The programming format is:
N4 G76 (contents of the block to be created).
The contents of the block to be created are similar to the normal programming except that
the preparatory functions G22 and G23 cannot be programmed. After G76, the coordina-
tes can be programmed in different ways:
a) X+/- 4.3 Z+/-4.3
Loads the axes with the indicated values.
b) X Z
Loads the axes with the theoretical values that they show at this time.
c) XP2 ZP2
Loads the axes with the values of the parameter at this time.
In the same way, if we program in the contents after G76:
FP2 or SP2, the CNC will load the F or the S in the new program with the values of the
parameter at that moment.
Example: Let us assume that the X coordinate of the point where the machine is situated
is 78.35. If we execute the following program:
N10 G76 P00345
N20 G76 G1 X F500 M3
N30 P2=P3 F2 K1
N40 G76 XP2 ZP5 M7
N50 G76 G0 X14 Z20 M5
