Key copying machine

The pink sample key and yellow key (to be made) are clamped on the blue oscillating table.
The brown cutter spindle is driven by an electric motor vie a belt drive (not shown).
The operator (red arrow) forces the pink sample key towards the brown tracer and the brown disc cutter creates key slots on the yellow key when the blue oscillating table moves in the longitudinal direction.
This movement comes from the worm drive (brown worm and yellow worm wheel), sine mechanism (yellow worm wheel, blue slider, pink shaft) and orange latch.
In simpler machines this movement is performed by the operator.
This design was made based on video:

Hello Mr Thang. Thank you for all the most excellent simulations, there are some very inspiring mechanisms beautifully animated. I have come up with what I consider to be an interesting mechanism. Probably it has been used before but I had the problem of switching a control arm inside a moving rotor. My solution was to run the switch lever (in this case a pin on a control arm) in a concentric groove. By shifting the groove so that it is eccentric to the rotation of the pin it forces the pin to have a smaller radius, thus rotating the control arm. You can see it on my TH-cam channel, which also links to my web page with a full description.

This makes so much sense. That’s why I love engineering. It will always make sense if you are willing to break it down.

what makes human lives better ? technology , not money , religion or politics

[@haroonmohammed6351]

The sword, spear, guns and nuclear bombs are technologies too.

⁠​⁠​⁠​⁠@@haroonmohammed6351 Those technologies aren’t that bad. They can also be used to improve your life in many different ways.

[@haroonmohammed6351]

@@JGambrosia well, if we are looking at it like that, then religion, politics and money have their own pros too. and those pros are too big to ignore.
religion was a major part in defining a sense of morality to large masses of humans who didnt know right from wrong. religion and the concept of god, and the greater good and bad and guided humans.
money is the way to exchange commodities in human societies. there was barter system, but that just didnt cut it. do we even have some system to replace the function of money ?
without politics, how are we to self govern ourselves. there would be chaos.

That's a clever mechanism!

Nice machine.👍

How about a design to raise and lower a grill grate, easily adjustable over a campfire, to regulate the amount of heat on a pot!
