Twisting & Bending Terra Cotta For The Alberta Dome Project
The CNC router is being put to use to produce models that twist and bend in all 3 axes. In this case the blocks are for a window surround in the lantern of the Alberta Legislative Dome. These blocks are ideal for our machine’s 5 axis capabilities as are able to match the surfaces perfectly through the use of continuous 5 axis milling. The cutting tool remains normal (perpendicular) to the surface geometry over its entire face. As the surface twists and bends, the cutting tool follows it exactly creating a superbly accurate model.
