AndysMachines: Digitally (PIC chip) controlled synchronization between hob and gear blank, Pt 1:

Oh, good grief! I am five minutes into the video and I can plainly see that we are going to have to watch it being made, piece-by-piece. With absolutely no explanation of what the design theory behind it is or what is going on.
AAAAAAAAHAG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1111
I would like to know what the hole saw is?
Ralph
Sorry Paul, for not informing about the non-informative, tedious and perhaps non-pedagogic process beforehand.
That said, I personally like following the machining sometimes just to see what decisions is being made when,
and try to figure out the ideas and methods used. For instance: Not a single carbide insert, "merely" HSS lathe tools used throughout.
I'm also biased in having some interest in DIY hobbing, and learned quite a few bits from it.
But then that's just me - and "to each his own" I guess...
Ralphxyz: Seems to be a run-of-the mill Sandvik HSS 60 mm OD hole saw*:

The video must have been speeded up cause that run-of-the mill Sandvik HSS 60 mm OD hole saw cut through the steel like butter.
Ralphxyz
Yup- the shot was indeed speeded up as well as cut/ POV changed three times.
A PIC chip? Andy from Andy's Machines must be a pensioner.
All kidding aside Andy's Machines is a pretty cool channel. He builds lots of really cool stuff. The Terminator eyes video is pretty neat.
Caution: NO drawings, sparse comments, some machining that might be disturbing to sensitive watchers.
Watching this video is NOT MANDATORY.

Hey Nova. Might you have a more specific URL for Andy's Machines? Did the Google thing and all I got was professional business machine shops. Didn't seem to be what I was looking for.
PS Great job Swede!!!
Here you go. This is the Terminator eye build. It's purely artistic, but still very neat. He makes a working mechanical iris.Quote:

Thanks Nova!!!
Dear DIYSwede,
the combination of mechanical insight, the poaching of electr(on)ics and the craftsmanship leaves me awestruck.
Not to forget the perfect visulisation.
These publications encourage the less experienced to venture more difficult and more rewarding tasks.
Nice to find some ideas or baits to pocket for one's own work - like the numbers-etching.
"Andy's Machines" strikes again! The Ju-Ju Magic behind hob making now explained in easy-to-grasp lingo!
13:14 mins video, including design theory, graphics, formulae and math needed to actually measure the tip width of a 40 deg hob cutting tool! Enjoy!

PS: -Now - Andy got himself a MOD cutting lathe, but for the rest of us there's some very interesting change gears combos involved, hinted here:

This documentary is 9:16 mins long.

Seems like Andy realized Nova Robotics amazement for his original controller using a Pic chip,
and perhaps also Paul's frustration above over sparse or no comments in his videos...
So Andy just put up an Arduino*-based hobbing motor controller instead,
including his entire, easy-to-follow design considerations & process.
Best of all - he also offers all the Arduino and 3D print stl codes free of charge:

*Of which Andy sez: "I know they're supposed to be quick and easy - but that's just what I don't like about them."
