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.

4.196 Special Problems in Architectural Design Complete Fabrications Nick Gelpi Mon-Fri, Jan 5-7, 10-11, 13-14, 18, 20-21, 24-25, 27-28, 01-04:00pm, 3-402/7-432studio, 1st mtg Wed 1/5 Pre-register on WebSIS and attend first class. No listeners Prereq: Permission of instructor ; Yr-1 MArch students who have completed 4.123 only Level: H 9 units Standard A - F Grading Can be repeated for credit Lab Fee: 150 A comprehensive introduction to methods of “making” explored through a wide range of brief but focused exercises. Skills = developing complex geometries from flat components; fine-tuning press fit construction, molding and casting, and making repeatable molds for customization. A two-part workshop, the first half will contextualize contemporary tools and techniques within the trajectories of historical case studies of building, combined with hands on familiarization of tools. The second half will implement the tools of our workshop in the context of Design. Working on group design build process for three MIT 150 FAST installations, students will test and influencing designs through the instrumentality of production. These hands-on design build projects are intended to produce reciprocity between skills and design, making more complete the problems of fabrication. Subject limited to year-one MArch students who have completed core-1 studio. Contact: Nick Gelpi, 9-224, 253-9415, ngelpi@mit.edu -
