6.6 Generating Contour Programs
from DXF Data (Software
Option)
Function
DXF files created in a CAD system can be opened directly by the TNC,
in order to extract contours or machining positions, and save them as
conversational programs or as point files. Plain-language programs
acquired in this manner can also be run by older TNC controls, since
these contour programs only contain L, CC and CP blocks.
If you process DXF files in the Programming and Editing operating
mode, the TNC generates contour programs with the .H file extension.
If you process DXF files in the smarT.NC operating mode, the TNC
generates contour programs with the .HC file extension.
The DXF files to be processed must be stored on the hard
disk of your TNC.
Before loading the file to the TNC, ensure that the name
of the DXF file does not contain any blank spaces or illegal
special characters.(see “File names” on page 110)
The DXF file to be opened must contain at least one layer.
The TNC supports the most common DXF format, R12
(equivalent to AC1009).
The following DXF elements are selectable as contours:
„
LINE (straight line)
„ CIRCLE (complete circle)
„ ARC (circular arc)
