01b_press-fit_lamp shelf design

I love the calmness of classical Chinese lamp shader.

The design composes of three parts, respect and reflect to “platform, body and roof” of traditional Chinese structure. “Roof” is a lamp shader, “body” is bookshelf.

1/2” plywood, Shopbot CNC, Straight end mill 1/4”

Fillet the interlocking corners, tab linear thin pieces

Profiling, cut depth 0.575, pass depth 0.2, step over 0.1, spindle speed 15000RPM, feed rate 200 in/min

separate profiling toolpath, outside one for outlines, inside one for inner circles.

I first tested two pieces to check the press-fit situation. Good.

Then all the press-fit joints fit well together.

This is how it looks at home

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, -
