Press Fit_Box^4

Concept diagrams For Nested Boxes

Press Fit was the introduction to the 3 axis mill. This project was completed using 3-d modeling in Rhino, Tooling set-up in Vis_Mill, and  cut using a Techno 3 axis mill with 4 x 8 bed. The goal was to get acquainted with the materials, software and tooling.

I need a place to put some books and I wanted to create something that could be reconfigured for multiple functions. To put it simply, I designed a series of boxes that nest, telescope, and interlock or, can hang independently on the wall.

The different connection types allowed me to test tolerances for press fit, slip fit, and peg connection. I used a 1/4″ endmill bit and dog boned all interior corners to eliminate fillets. I offset the press-fit connection to 0″ tolerance. I offset the slip joints .02″ for reconfiguration. I offset the nesting of the boxes 1/8″ to be sure never to have one box stuck inside of another.

If I were to do it again, I would use a 3/16″ endmill bit, be extremely critical to how flat the original sheet material is, and most likely think of creating more complex geometry. I look forward to using these connection types in conjunction with surface milling in the future.
