Re: [Emc-users] What does "CNC" really mean?

In the 40's I wonder how many of the parts were done on automated tools. They would not be "CNC" but they might have been build on specialized tools that only make one kind of part.I think this is a lost technology. I worked a little bit on aircraft and what I saw was a huge dependance on

Re: [Emc-users] What does "CNC" really mean?

Surprising that just for the fun of doing it, someone hasn't built a punched tape reader for a 3D printer. Would be much less complicated that the old machines, just encode G-code to hole patterns and have a reader for the tape send the code to an Arduino with a RAMPS board. From: Dave

I'm using the LinuxCNC 2.7.4 with the realtime support. Does the "2.8 pre" have the same RT support? Danny John Thornton wrote: > Yup > > On 8/30/2016 1:56 AM, dan...@austin.rr.com wrote: > > So, I have to switch to 2.8-pre for JA? > > > > Danny > > > > Charles

[Emc-users] Extended g33 question

Greetings all; Assumeing I have the tapered thread I want, can I continue that thread without the taper if I don't change the Z resting point while its waiting for an index pulse and motion.spindle-at-speed true. What I would like to have is the ability to unscrew the bearing axial pre-load

Re: [Emc-users] What does "CNC" really mean?

When we were refurbishing the B-17 I was often amazed with the thought of all those precision parts produced mainly by hand. 20,000 B-17s X 4 engines X 18 pistons + spares = one huge chunk of machine time. A person could wear out several pairs of boots standing in front of a lathe for that

Re: [Emc-users] What does "CNC" really mean?

Back when the term "CNC" was coined there where other non-numeric methods of controlling machines. and there where non-computer methods of machine controls. It was possible to do numeric control with no computer (using punched paper tape) and you could do non-numeric control using mechanical

Re: [Emc-users] What does "CNC" really mean?

I'm probably dating myself, but back in 1976 I ran an NC mill for a while at a shop in Detroit. I was pretty young back then. It was definitely not a CNC. You loaded it with paper tapes and hoped that the guy punching the tape in the front office did his job. The guy in the front office read

Re: [Emc-users] What does "CNC" really mean?

CNC is one of those acronyms that we are stuck with. The more things chance the more they stay the same. The term "Horseless Carriage' has mostly died out except here in Colorado where they still issue legacy "Horseless Carriage" license plates for extremely old vehicles. But today they still

We resurrected a MilwaukeeMatic IIIb. http://electronicsam.com/images/KandT/oldkandt.JPG http://electronicsam.com/images/KandT/DSCCurrent.JPG http://electronicsam.com/images/KandT/conversion/frntcontroller.JPG (we used a 386 as a tape emulator) The original control was used well into the 2000's

Re: [Emc-users] What does "CNC" really mean?

I remember my dad going to take an NC course at Sundstrand. The concept of NC (Numeric Control) vs manual control was a big step in industry (think of looms vs Jacquard looms - a lot of manual labor between these technologies). The makers of big mills that milled parts for Bell Helicopters back

Got into a bizarre argument... so of course it was initially "Computer Numeric Control". I was noting people breaking it down to explain it to people as "which means it's 'computer numeric controlled'" but that seems to add nothing to the meaning. In fact it's confusing. It's
