Alternating cutting depth
Instead of working with constant cutting depth D, you can use an alternating cutting depth to
vary the load on the tool edge. As a consequence you can increase the tool life.
The percentage for the alternating cutting depth is saved in a machine data element.
Please refer to the machine manufacturer's specifications.
To avoid the occurrence of very thin cuts in cut segmentation due to contour edges, you can
align the cut segmentation to the contour edges. During machining the contour is then
divided by the edges into individual sections and cut segmentation is performed separately
for each section.
Set machining area limits
If, for example, you want to machine a certain area of the contour with a different tool, you
can set machining area limits so that machining only takes place in the area of the contour
you have selected. You can define between 1 and 4 limit lines.
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.
Please refer to the machine manufacturer's specifications.
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 that the name of the main program must not end with "_C" and a two-digit
number. This is monitored by the cycles.
For programs with residual machining, when specifying the name for the file, which includes
the updated blank contour, it must be ensured that this does not have the attached
characters ("_C" and double-digit number).
