When I lent my services to a collegue who was working on a film about 12 years ago, I was introduced to the world of cnc. I remember watching this huge machining centre milling out a slab of mdf and turning it into a fantastic set of gears. I knew that it would have taken me hours to achieve the same thing with traditional power tools. I decided then that I would invest in a cnc router for my own business Oxenham Design. At that time I could turn on a computer, but even to check email seemed like a crazy set of operations. I persevered and learned every piece of relevant software I could get my hands on. I am now fortunate enough to be using Vectric's ASPIRE software, and Techno cnc routers, which has helped us to create some amazing projects, both in part, or in full. I thought that this blog would be a great place to share "behind the scenes" adventures with the software, materials and equipment we use, as well as the projects we build.

The next step was to apply a toolpath that our router would use to machine the parts. I used a 1/2" ball nose cutter to reduce machining times as the model was definitely large enough that it would still have lots of detail. After running a simulation, I could see that the eyes didn't have the detail I wanted. Easy enough. I drew a vector bounday around each eye and applied a 1/8" cutter tool path to just that area. The final step was a cut out pass.
