Analogue counterpart of CNC

Postby SunsetBoulevard » Sun May 24, 2015 6:17 am

I wonder if there has ever been an analogue version of the precision mill?

It all started with Tracers, which were followed by early Numerical Controls, followed by the Computer Numericable Controls. 8-)

This is a similar question to the one I saw the other day on Reddit. I cannot find it now, but I think they said something in the lines of the very first CNC’s being Agroloc, made in the 40’s. They were programmable, kinda.

Actually, I think you are talking about the Acroloc machine. They were programmable (in a semi-NC sort of way). They relied heavily on hydraulic systems that were adjustable on the axes.

Nah, the hydraulic systems were introduced in the DSMA lathes, not the Acrolocs.

So, were there any cams used in these?

Yeah, IIRC there was a mix between CAMs and custom tools which were designed to achieve the tasks needed to be achieved. :)

The NC’s that you speak about are what I think are the analogue version of the current day cnc’s. There was no computer involved, right? So that is why they are called NC’s without the C.

So, if they were not using computers, what did they use to obtain the directions of what to do? I cannot even begin to imagine what it must have been like to aid such a machine. The computers in the 40’s were giant pieces of equipment. I do not understand how they worked…
