184 8025/8030 CNC PROGRAMMING MANUAL
Sequences and explanation of operation:
1. If the spindle was previously running, it keeps on rotating in the same direction. If it
was not running, it start clockwise (M03).
2. Movement from the starting plane to the reference plane in rapid G00.
3. Movement at the working feedrate of a distance equal to B+D.
4. Dwell K in seconds, if it has been programmed.
5. Withdraws in G00 either a distance equal to H or to the reference plane according to
the value given to J.
6. Movement in rapid to a distance C, before the previous penetration.
7. Movement at the working feedrate of a distance equal to B+C.
8. Dwell K in seconds if it has been programmed.
9. Operations 5 to 8 are repeated, until reaching the penetration I.
10. Depending on the function programmed G98 or G99, the tool withdraws either to the
starting plane or the reference plane in rapid.
Atention:
If the value given to parameter R is equal to 1, all the incremental
penetrations B are equal (B1=B2=B3=B4).
If the mentioned parameter is different from 1, the different
penetrations will be: B1=B; B2=RB1; B3=RB2; B4=RB3.
In both cases, the last penetration will be determined by the CNC,
according to the value of the total penetration I.
If we program for instance, B=12 L=9 R=0.9; the incremental penetra-
tions B will be:
B1=12
B2=0.9X12=10.8
B3=0.9X10.8=9.72
B4=0.9X9.72=8.748
As B4 is smaller than the minimum penetration L, from B4 on, it
included, every subsequent penetration will have a value equal to L, that
means equal to 9.
