4 MILLION Lines of G-Code with RhinoCAM at PBE!
Anthony Pelosi, CNC Lead at PBE (Paul Bernhard Exhibit Design & Consulting) located in Austin TX, recently discussed one of his RhinoCAM projects with us. It involved the topographic exhibit design and production of a geographical site recently designated a World Heritage Site by the World Heritage Convention (an organization of UNESCO). The geospatial data was loaded into Rhino 5.0. The 3 Axis Parallel Finishing operation that RhinoCAM posted to PBE’s Laguna Shop Smart 2 CNC machine packed a total of 4,041,337 lines of G-code (23 hours of machine time). Refer to the figures below to learn more about this amazing project!
Refer to Figure A above:
- The high-resolution surface elevation terrain model is displayed in Rhino 5.0.
- The RhinoCAM Machining Browser is shown on the left with the Machining Job defined comprised of a 3 Axis Setup, a 3 Axis Horizontal Roughing and a 3 Axis Parallel Finishing operation.
- A closeup area of the terrain model (inset upper-right) shows clear details including river basins, mountain ranges and estuary runoff!
- The same section (insert lower-right) is shown with the 3 Axis Parallel Finishing toolpath superimposed on the surface terrain model.
Refer to Figure B above:
- The RhinoCAM Machining Browser is shown on the left with the Simulation tab selected.
- The 88”x34”x4” stock model is shown with cut material being simulated.
- The 3 Axis Horizontal Roughing operation contains 650,000 lines of g-code and is shown previously simulated on the far side of the stock model using a ¼” ball mill, an offset cut pattern, a step over of 40% (of the tool diameter), a step down of 50% and a stock offset of 0.025” left on the part.
- On the front side, we see the 3 Axis Parallel Finishing operation in the process of being simulated.
- A close up of the toolpath cut material simulation shows the river basin and estuary runoff shown in Figure A(3) above being simulated.
- The 3 Axis Parallel Finishing operation contains 4 MILLION lines of g-code shown in the RhinoCAM Toolpath Editor. The operation uses the same ¼” ball mill with a stock allowance set to zero (finish cutting on the surface of the high-resolution terrain model) at a 12% step over.
