Turn-by-Wire: Computationally Mediated Physical Fabrication
summary
Turn-by-Wire is a lathe retrofitted with motorized hand wheels that modulate both position and force through electronic braking and an impedance controller, with control logic in client-side JavaScript and 10–20 ms roundtrip latency. It implements snap-to-guide haptic limits, virtual tool remapping that lets one wheel trace arbitrary paths, and a record-playback copy/paste for toolpaths. Five expert makers produce a benchmark widget in 15–20 minutes after 15 minutes training; snap-to-guide rates 4 strong agree and 1 agree for usefulness.
