You could not have done this with 1970s tools and CAD.[1] [1] https://www.youtube.com/watch?v=Bqv5SjC4s6w

This was absolutely machinable with late 1970s CNC mill. Probably pain in the ass to design with then existing CAD/CAM but ultimately this demo runs on same G-Code that was there in 1970s. And as far as parlor ticks go this is not particularly impressive, compared to old ones like turning cube inside a cube on a lathe.

That’s a bit like saying “most large modern systems are written in C which was invented in 1972, therefore software engineering has not changed since the 70s/80s”. That machine is also probably not running a gcode flavour that would have made sense in the 70s anyways, with additions for active sensing, macros, etc.

Tools like UNISURF would probably not be able to handle the extreme level of detail on most of that model. The very long tool lengths you see in the video are much more complex than they look and require effort both from software and hardware to prevent chatter and breakage on titanium. The clearances in the video are also extremely tight in places, and while you could have guess-and-checked that in the 70s, it’s a very different workflow than the simulators that are basically standard use today.

CNC machining is a multi-billion dollar industry populated by smart people. While the fundamental technology of “spinning cutter driven by computer controlled motors” hasn’t changed in 50 years, the R&D departments aren’t asleep at the wheel.

Do you, or anyone else here, know how much money Apple saved by offshoring? I sometimes get it. Then when I hear robots were used, I wonder if it's really necassary to always go to the cheapest labor route. For years, I held it against Apple for moving manufacturing, but gave up when everyone followed.

> Do you, or anyone else here, know how much money Apple saved by offshoring? There's another axis here, which is how our desire for a product overlaps with DFM. It could be the case that offshoring to cheap labor actually increased the manufacturing costs 2x, but enabled a product that would sell 10x better than its DFM counterpart. (I have no data to say that is the case, only the intution that these things are com…

For those unfamiliar, DFM = design for manufacturing. I had to look it up.

How is lede pronounced? Like lead?

When typesetting a printed newspaper, the leading (pronounced like “ledding”) is the space between lines of text, originally physical strips of lead (Pb).

The lede (“leed”) is the most important statement in the story. The word comes from “lead” (also pronounced “leed”), because it's the statement that everything else should follow. It's conventionally spelt differently to avoid confusion with “leading”.

Those have gotten way worse. It’s an SEO thing right?

It's viewed as a DRM measure. Recipes are not copyrightable unless they are attached to a story. It's probably an urban legend, but can't blame poor food bloggers from acting on it.

I'm pretty sure recipes aren't copyrightable, even when they are attached to a story.

Machining grade 5 titanium alloy (the most common one) is not especially challenging; it's easier than 316. Saying this as I did machine it personally on a manual lathe.

From the initial endmill size they use and the generous machine sizes (which can be extrapolated from chuck/table size) we can easily tell rigidity/chatter wasn't a particular challenge here. And the finishing passes are so delicate they don't even bother with coolant for that.

Yes the code to run all this would be a monumental undertaking in the 70s but it is done once and can be still entirely cost efficient as far as mass production is concerned. The thing new machines have is the running speed (for same precision work). These did improve a lot and make certain classes of products economically viable.

I like inverted pyramid style too, but it’s a very brief intro and letting the CEO of a new company introduce themselves doesn’t seem so bad? You could skip the first paragraph.

I often don't know how much to skip. Where is the point? I often give up unless it's something I'm really interested in.

That's probably for the best. Reading things just because you're there, even though you're not actually curious about them, seems like a bad habit.

I can understand why the style may seem offputting, but the thing to understand is that it has been traditionally very hard to engage with the public on this topic of robotic advancement. In fact, I know a bit about this myself, having been in the robotics space for over a decade. But my own struggles in the field only reflect a longer trend, which I can even trace back to my grandfather. Growing up in a strict Luthe…

Is this autobiographical or is the similarity between the nickname Kazoo and your HN username khazhoux entirely coincidental?

He's talking about his grandfather, so it is not a surprise he has the same last name

Does copyright for a story containing a recipe protect against use of the recipe outside the context of the story?

I think the question is “is it possible to split recipe from BS story programmatically”

Generally yes. Most recipe blogs use semantic markup so that Google recognizes it as a recipe, which also makes it easy to scrape programmatically.

You will not be a fan of recipe blogs anywhere on the internet.

I want an AI browser plugin just for recipe sites called GTTP (Get To The Point).

Probably could build it with regex, actually.
