Solid Aluminum Stallion Machined Using Five Axes

This sculpture differs greatly from standard fabrication approaches by utilizing five-axis CNC techniques on a single solid piece of material. The maker transformed a silver-colored metal stock into a rearing horse. Instead of a standard setup, the metal piece is secured within a machine vise, which itself rests upon a rotary trunnion table. This configuration allows the machine to access all necessary areas through complex movement.



For the actual sculpting, the maker employed a multi-axis CNC milling machine equipped with a tapered tool holder and a fine milling cutter. The rotary table tilts the workpiece at various angles, allowing the tool to reach details on the horse's body, flowing mane, and the attached base plate. The maker achieved a smooth finish by executing multiple light passes with a small ball nose cutter.



This approach resulted in a finished rearing horse sculpture that stands on its hind legs and features a clean surface. While the final result looks excellent, the total time required to complete the machining process remains unknown. It is interesting to see how this build compares to traditional methods of forming such detailed pieces.

The use of a rotary trunnion table seems like a clever way to manage tool access while machining the horse's form. It must trade off some setup time for the flexibility required for complex geometry.

Could you elaborate on how the maker achieved the smooth finish mentioned, considering the multiple light passes and small ball nose cutter?

The maker used multiple light passes with a small ball nose tool to achieve a smooth finish. The machine was used to machine details into the horse's body, mane, and base plate using a tapered tool holder and fine milling cutter.

Using a different type of milling cutter, perhaps one designed for finishing, could provide an even finer surface quality. This would allow the maker to potentially reduce the number of light passes required for the final result.
