CNC imports DXF files directly
The widespread use of DXF files created in CAD programs has lead Heidenhain to develop a function that allows direct import of these files to its iTNC 530 CNC control system.

Set up times have been cut by half and tool setting optimised following the installation of Heidenhain touch trigger probes and tool setting probes at Cross Manufacturing (1938).
Contouring CNC and encoders speeds EDM
Heidenhain's TNC 416 contouring control system and linear and rotary encoders on a Sparcatron five-axis EDM has eliminated tooling changeover in machining turbine blade bleed holes.
Files can then be opened in the same way as standard NC program with the iTNC control recognising the type of operating mode, either Heidenhain's SmarT.NC or programming and editing mode, used to open the file.
Users can then extract the specific contours and save them as a plain language program.
Normally within DXF files there are multiple layers of information, which a designer has used to create the structure and group certain elements.
To simplify what appears on the screen of the iTNC 530 unnecessary layers are hidden through simple mouse clicks.
To further streamline use of DXF files the iTNC control has a function that allows a drawing datum to be re-positioned to a more suitable location for manufacturing purposes.
For instance at the beginning, end or centre of any straight line, circle or arc; at the transition between quadrants or the centre of a circle or, at numerous intersection points whether they be on straight lines of circles.
Once the reference point is set and the required layers selected the contours to be machined can be chosen.
Using simple mouse clicks contours are picked and the control detects the desired direction of machining and begins its Automatic Contour Detection procedure.
The control then automatically selects all clearly defined contour elements until the contour closes or branches out.
If the latter occurs then the operator is required to click the next contour element.
Using this process it is possible to select extensive contours with just a few clicks of the mouse.
Once the defined contour is saved it is available for use immediately.
Finally, for visual verification the iTNC 520 provides a powerful zoom function to ensure that all contours blend and a variety of functionality settings that enhance program output, for instance, if you wanted to use the program on older TNC controls.
