Java AP-238 Toolpath Viewer

The view238 application is a simple tool for graphically displaying STEP-NC toolpaths. It is a Java application that reads AP-238 XML data using the DOM inferface, then finds and display the toolpaths within. At present, only polylines, and circular arcs are processed.

This toolpath viewer is completely open-source and released under the GNU Public License. It was developed as a simple companion to the open-source STEPNCWrite library. For more sophisticated applications, we encourage you to look at ST-Machine, our commercial STEP-NC product.

To run the program, download the zip file, and double click on the jar file within, or from the command line run "java -jar view238.jar". Some example data files are shown below, along with screen captures comparing the toolpath viewer with the ST-Machine Explorer.

These are complete STEP-NC data sets, with toolpaths, workpiece geometry, fixture geometry, and tool geometry information. In addition to the XML data, we have provided an HTML version of the data so that you can easily examine the data contents with a web browser.
