If you have ever run a cnc machine you surely will have come across the Optional Block Skip. On some cnc machine controls it is also called Block Delete.
“/” is used as the skip sign.
The cnc program blocks which has skip sign prior the program block just skipped or omitted when the cnc program is executed.
The cnc program example is under
N5 G00 X20 Z0 /N6 G01 X0 F0.2 /N7 GO1 X20 N8 G01 Z-20
The above cnc program when run or executed on a cnc machine
the cnc program block number 5 and 8 will only be executed,
and block number 6 and 7 will be skipped or not be machined.
Optional Block Skip or Block Delete only works if the optional block skip swith is “on.”
