Radius Slide Rule Gallery

Objective:

Build a slide ruler to measure the radius of a curved surface.


Processes:

  • CAD: Model kinematics/component geometry
  • CAM: Program toolpaths for components/fixtures
  • Milling/laser etch components

Materials:

  • Richlite: Probes, Body
  • Stainless Steel: Hub/Data Plate
  • Brass: Rivets, Rack and Pinion (outsourced)

Outcome:


Instrument successfully calculates the radius based on chord length and sagitta, displaying the result on a contour plot.
