So, I have a sentence:
The amount of workers had increased significantly when CNC machines were launched.
I wanted to say that when CNC machines were launched (or have been launched, not sure), only after that the amount of workers increased.
Is my original sentence correct?

It's perfectly cromulent, but it doesn't say what you want it to say.
The had increased locates the increase at a time before the time that you are focussing on (which is not expressed). It says that the increase and the launch were at the same time, but it does not clearly say that the increase was after the launch (though that is a possible reading).
There is a possible alternative reading where the launch is the temporal focus, and the increase is located before that; but I would expect a comma before "when", and pragmatically it does not seem likely in this case. But in
the falling is definitely located in the past relative to the seeing.
