We have done two partial tests in the CNC, equivalent to a beer for each one. Tested both transparency and endmills, we now have explored some fundamental parameters for the further development of the moke-up model for our modular (modular-parametric, parametric-modular) cealing. The built models made us realize the importance of the lines drawn by the mill, considering the fact that the surfaces can be defined by curves. We will take this fact into account when wrapping up the final script. The two tests show a certain tendency to carve too thin sections in unexpected areas of the model, where the material easily breaks so that we will need to fix the minimum thickness for a propper transparency effect to be achieved.
