Morphology

helicoid = helix (transparent) = helic + oid

The mechanical part sense is a concrete application of 'helix' + '-oid' (spiral-shaped), so the composition is straightforward.

Etymology

Helicoid for a mechanical part shares the roots helix 'spiral' and -oid 'like', as in asteroid. So a helicoid is a spiral or screw-like sleeve that moves parts along a path, which explains its use in lenses and machines.
