With FreeMILL you will be able to:
1. Create a toolpath where the tool is driven along a set of parallel planes to cut your geometry
2. Create both Roughing and Finishing toolpaths
3. Run full cutting and material simulation of toolpaths
4. Output G code to your CNC milling tool of choice
FreeMILL is not a separate product but is a module that is included in each of these products: VisualCAD/CAM and RhinoCAM. FreeMILL thus runs either standalone (no other CAD system required) or as a plug-in to CAD systems Rhinoceros.
