1.2 General function
1.2.4 Plane generation
Basic input format:
DXF input formats as defined by AUTOCAD
After conversion, NC programs can be saved as file types
When a file is saved, the CAD Reader creates G code (NC blocks)
from the selected contour. This code can be processed directly with
Comment blocks which can be processed by the geometry processor
or the cycles support are saved at the same time.
Imported contours can be recompiled or modified by means of the
Drill holes are generally generated in cycles format and can thus be
recompiled on the control.
Generation of relevant data
When the relevant data are saved as part program blocks, they are
converted to MPF format by the geometry processor and the
appropriate planes G17, G18, G19 are generated.
Technology data are not specified in the CAD Reader, but must
generally be programmed in the editor or the geometry processor.
NC milling programs are created only in the 2D machining plane.
The infeed axis must be programmed later.
