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:
Lathe change gears combos: Gain distribution problem.
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:
Video is 16:58
*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."
