Define a new profile, enlarge an existing one or import one from a file.
9.2.5 Import a profile from a DXF file.
The DXF format is standard for exchanging graphic files. The CNC can import this type of
files and, based on the contours and tool paths it contains, generate the ISO-coded blocks
of the part-program.
DXF files may be imported and modified in the program editor and in the profile editor. After
selecting the file, define how the various layers of the DXF file are to be interpreted.
How to draw and lay the drawing out.
How to draw the contour and other elements (items).
Laying the drawing out in layers.
A DXF file may be divided into layers offering the designer a way to lay the drawing out.
Although each layer can contain any type of information (layers, dimensions, etc.), it must
be borne in mind that the CNC uses the layers to define the order of the machining operations
and the height where they will be carried out; therefore, the following rules must be followed.
• A layer must not contain profiles located at different heights. When importing the file, the
CNC puts all the contents of the layer at the same machining height.
• Profiles placed at the same height may be on different layers.
• The elements that are not part of the machining operation (axes, dimensions, etc.) must
be placed on layers that do not contain contours so the CNC can ignore these layers when
importing the file.
Exporting the file to DXF format.
The DXF file must be in ASCII format, files in Binary format are not permitted. When
generating the DXF file from the drawing program, make sure that the file is saved in ASCII
format.
When generating the DXF file from the drawing program, select a 4-decimal resolution is the
CNC units are millimeters or 5 decimals if the measuring units at the CNC are inches. A
greater resolution increases the size of the DXF file unnecessarily because the CNC ignores
the excess of resolution.
Element.
Origin (zero point) of the
drawing.
The CNC uses the drawing zero point as part zero.
Measuring units. DXF files do not contain any references to measuring units (mm or
inches); therefore, the CNC uses the ones defined in the part-program.
Contours. The DXF can consist of points, lines, arcs and polylines, but they must
be previously decomposed (uncombined). If the file contains polygons,
they must also be decomposed; otherwise, they will be ignored.
Holes. Drilling, tapping, etc must be represented with a single point. The CNC
interprets the circles that represent the drilling, etc. as paths to be
machined.
To keep the look of the drawing intact, place these elements on a layer
so the CNC can disable this layer when importing the drawing.
