<title>DXF to NGC Converter: dxfncg</title>

<title>Introduction</title>

<para>

The DXF to NGC converter <emphasis>dxfngc</emphasis> provides a
      means to convert 2D technical drawings in DXF file format to G-code
      in NGC format used by CNC mills or routers (e.g. LinuxCNC).

</para>

<para>

Usually, the 2D drawings in DXF format do not contain enough information
      for G-code creation, e.g. about which lines describe the border of a part
      and which lines describe holes.  The diameter of the cutting tool and the
      depth of the cut are other examples.  Therefore, dxfngc relies on a
      script file to control the G-code generation.  This script is the input
      to the tool.  It sets all required parameters, reads the drawing,
      controls generation of the G-code and finally writes the output file.

<title>A first example</title>

<para>

To illustrate the usage of dxfngc, suppose a stencil for a logo shall be
      cut with a CNC mill.  The basic shape of the stencil is a circle.  The
      logo is formed by two holes with a specific shape (see <xref
      linkend="logo_stencil"/>).

</para>

<para>

First, the 2D drawing is created with a CAD program in DXF format.  The
      circular border is drawn on layer <parameter>border</parameter> and the
      two holes are drawn on layer <parameter>holes</parameter> (see <xref
      linkend="logo_drawing"/>).
