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.
