    We know that F1 teams over the years have gone through lots of fancy
    processes and materials to cut the weight of parts and still be
    strong. I've been looking on Youtube and found a process called
    "electric discharge machining", which gives tolerances of the
    thickness of a thin wire.

    Would an F1 team use such machines to give effectively zero
    tolerance cutting for mechanical parts? Looking at it it is
    amazingly accurate cutting, far better than a CNC milling machine,
    but massively slower.

    EDM has been around for quite a while now and I dare say that if it
    brings a benefit to anything an F1 team is doing they'll certainly be
    using it.

    Steve Mould did an interesting vid on the accuracy and precision of wire
    EDM a while back:

    Spoiler: the two bits that fit together perfectly aren't cut from the
    same block, as some material has to be lost.
