Algorithm Aided Design. This project can be classified under this. However, the focus lies on parametric design and its manufacturing process. All surfaces were created with the help of Grasshopper and can be freely designed by using variable parameters. The patterns are visualizing interferences, which are determined by two triggers points. From those variable points two oscillating sine waves in x & y direction are superimposing each other. These interference effect is creating the surfaces. Additionally, it has been necessary how to manufacture the designed objects by the help of an abrasive manufacturing process. I decided to generate numeric code with a little help of a CAM module to run it on my CNC Mill and to make the result physically tangible.
