38 8025/8030 CNC PROGRAMMING MANUAL
When the block 10 is reached, the CNC jumps to block 50 and then the program continues
until it is finished.
b) N4 G25 N4.4.2
N4 > Block number
G25 > Code unconditional jump
N4.4.2 > Number of repetitions
> Number of the last block to be executed
> Number of the block to which the jump is targeted
When the CNC reads such a block, it jumps to the block identified between the N and the
first decimal point. It then executes the section of the program between this block and the
one identified between the two decimal points as many times as set by the last digit. This
lastdigit can take a value within 0 and 99, unless it is programmed using a parameter in
which case the limits are 0 and 255. If only N4.4 is written, the CNC will assume N4.4.1.
When the execution of this section is finished the CNC goes to the block next to the one
in which G25 N4.4.2 was programmed.
Example:
N0 G00 X10
N5 Z20
N10 G01 X50 M3
N15 G00 Z0
N20 X0
N25 G25 N0.20.8
N30 M30
When block 25 is reached, the CNC will jump to block 0 and will execute 8 times the
section N0-N20. On completion of this, it will go to block 30.
Functions G26,G27,G28,G29 and G30 will be described in the corresponding chapter of
this manual PARAMETRIC PROGRAMMING, OPERATIONS WITH PARAME-
TERS.
