Magnifying Glass
This was a project in Design and Manufacturing (ME 103). The goal was to manufacture a magnifying glass according to a series of engineering drawings.
Overview
Four manufactured parts make up the magnifying glass: the handle, the glass, the ring and the lug. The lug was machined on the mill while the handle, ring, and glass were machined on the lathe. The lug and handle are attached by custom threading while the lug and ring were brazed together using a silver alloy.
Machining Overview
Lug: Cube of raw brass cut to shape and threaded on the mill
Ring: Tube of brass cut OD and ID to size on lathe
Handle: Rod of PVC cut to shape and threaded on lathe
Glass: Rod of Acrylic cut to shape and curvature on lathe
Assembly
