After designing our CNC machine we started conducting a series of explorations in which the machining process is engaging with the material properties of the medium. We manipulated the thickness of aluminum sheets to incrementally form them. As the materials get scored and pushed, tension develops in the sheets giving it rigidity and form. In a parallel exploration, we displaced used the CNC to displace wet clay. The forming process introduces air in the clay making the material lighter, it could also potentially channel light and water.
