Makers of VisualMill for mills, VisualTurn for lathes and CAM plugins for Rhino (RhinoCAM), SolidWorks and Alibre (now Geomagic Design) This program does it all—2D and 3D milling, with support for 2.5D operations like pocketing and drilling, in an easy-to-use Windows environment, which allows toolpaths to be previewed in motion. VisualMill imports Rhino 3dm files as well as polygon formats like STL and DXF, and outputs standard g-code. This comes in several versions: one for basic 3 axis milling, another with support for a rotary 4th axis, and a third with that and many remachining functions. The ultimate version includes support for a 5th axis, with a custom post-processor written to the specifications of your milling machine. Now available at a discount price on this site.
