Figure 10-13 Impermissible limit: Limit line XA is inside the contour of the blank
Feedrate interruption
To prevent the occurrence of excessively long chips during machining, you can program a
feedrate interruption. Parameter DI specifies the distance after which the feedrate interruption
should occur.
The interruption time or retraction distance is defined in machine data.
Residual material machining / naming conventions
G code program
For multi-channel systems, cycles attach a "_C" and a two-digit number of the specific channel
to the names of the programs to be generated, e.g. for channel 1 "_C01".
This is the reason why the name of the main program must not end with "_C" and a two-digit
number. This is monitored by the cycles.
