The convenient support of the SINUMERIK CAD reader allows contours to be generated or drill points to be filtered out in just a few work steps. Unnecessary components of the drawing such as dimensioning, hachures, labels, and frames can be hidden and removed due to the layer technology. In addition, the CAD reader can convert CAD data (DXF files) into NC programs (MPF, SPF, ARC) for drill patterns and contours. The contours or drill patterns generated are implemented in such a way that they can be understood by the geometry processor or cycle support and edited on the controller. The CAD reader is available with SinuTrain or as a stand-alone application. To be able to read splines in the SINUMERIK CAD reader, they need to be converted into polylines.
