Example: Let us suppose that the X coordinate of the point where the machine finds itself is
78.35. If we run 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
and if in block 40 the parameter values are: P2=14.853 and P5=154.37, the CNC will
generate the following program P00345.
N100 G1 X78.35 F500 M3
N101 X14.853 Z154.37 M7
N102 G0X14 Z20 M5
It is necessary to program all five digits of the program number in blocks of type G76 P5 or
G76 N5.
The CNC must be in DNC ON (operating mode 7) in order to load the new program into a
computer (see DNC manual).
If the number of the program to be generated exists already in memory (e.g. P12345) it must
be in the last position of the program map; but if G76 P12345 is executed, the old program is
erased and the new one can be generated.
When the program number exists in memory but is not the last one in the memory map, the CNC
will issue error 56.
Atention:
When a program is edited it goes to the last position in the memory map and
when it is executed it goes to the first position.
When a program is being generated, another program cannot be generated
until the generation of the previous one is cancelled by means of M2, M30,
RESET or EMERGENCY.
Some of the applications of the G76 function are, for example, the creation
of a program after the calculation of a path by means of a parametric program,
or the DIGITIZING of a model with a measuring probe (G75) generating a
point-to-point program as large as desired.
