I personally love how effortless the machinery looks while being so precise and calculated, like us humans can't be perfect, we are chaotic as a whole. These machines however, the efficiency and precision looks like a sort of harmony. I also like clockwork, all the parts depending on each other and working at once to achieve a click. I think your question was more rhetorical though.
And yet someone had to spend countless hours using a less efficient machine to make said machine and then(in the case of some automatic manufacturing items) program it with their very own motion.
You'd be surprised how much it's really a kind of 'ghost'
all these machining gifs remind me of work.
had a pretty ****** day at work. was using the auto feed on the lathe and somehow i engaged it to plunged into my stock and apparently the emergency stop doesnt work for the feed.
Work with anything long enough and you're bound to make a mistake at some point. Just a bit scarier when you're working with machinery and not at a a desk job.
this is an example of planetary gears, automatic transmissions in cars are made out of planetary gears that are made with solenoid locks so that the car's computer car lock individual "planets" to change gear on a dime. manual transmission master race tho
Water has a lot of surface tension, which causes it to form spheres if undisturbed. For example, dew on grass always takes the form of a sphere, because the water isn't heavy enough to drip or run down/spread out on the grass, but the blade of grass also isn't absorbent.
The reason water isn't a sphere on most surfaces is because it either gets absorbed by the material or spreads out over the surface - neither is easy on a hydrophobic surface.
The way I see it, there are two possibilities, considering the slanted angle of the plate:
1: The plate was hot, so it created a small bubble of gas that repelled the water.
2: The water had just enough momentum to bounce off, but not enough momentum to break in smaller bubbles.
If none of these are applicable, then that was filmed on special conditions or rendered in some sort of alien supercomputer.
It's ABS. We were feeding a 1/4" 2-flute cutter at 6 inches per minute and 1000 RPM. If we went any faster we started to affect the surface finish.
If I didn't have tight corners on the outside I could've gotten away with 8-10 inches per minute with a 1/2" end mill, but the remachine operation would've taken up any time we saved.
It was a new experience for me as well. It tested my patience, had to resist bumping the feed up to 300%.
I did get the opportunity to work on some small parts last week. We made some wheels for a clock that were about the size of a quarter, and my butt puckered every single time the tool got near a clamp. We was done in 3 minutes though, so that was nice.
