Ongoing research on surface articulation using CNC-milling manufacturing processes. Various fabrication strategies are applied to doubly-curves surface geometries in order to increase efficiency of the production and integrate limitations and constraints of the machines into the very early stage of the design process.

This study explores various patterning strategies applied to a given doubly-curved surface using 3-axis CNC-milling manufacturing technique. The three-dimentional surface articulation is designed through optimization of the drill trajectories and sizes of the drill tools. It aims at optimization of the machine performance, aiming and maximum efficiency of the fabrication process and minimization of the manufacturing time. Given manufacturing technique becomes main design driver and form-defining factor.
In this case we optimize the applied pattern in order to mill the final iteration right after the “rough cut” and skip smooth finishing of the surface – the phase that occupies most time and energy.
