My impression of the standards process is that it is intentionally setup to EXCLUDE all but the moneyed elites, whether they be academe, government, or industry. In no way do ANY of the standards organizations have any but their own self interest at heart. Why does it cost $65.00 for a copy of the G-code standard? This document should be free, given to every student and supplied with every machine. It's ONLY 29 pages. WHY DOES IT COST $65 plus S & H!!!!!!

If it's done with tax money then it should be available in libraries.... Are they available at my public library... No not as far as I can see... bu may be I did not search enough... The point Fred, is ..... with the advent of the internet, it should be in the public domain, for downloading or viewing...

The bureaucrats and academics want to perpetuate the process until they retire, the industry participants are paid consultants wages, and don't have to do much work when at committee meetings, and the corporations that actually fund much of the standards process do everything in their power to make sure that their special little twist gets embedded in the standard.

Yep ! If the g-code standard was funded by tax money ( I'm not sure how it was funded ) there is no reason why they should charge anything at all for it..

I needed the NMEA ( not NEMA) standard a while back, and they charge about $100 for it... but that's fair, it's a privately funded organization, and my tax money did not help fund it, so, I see it's fair they can charge whatever they please for a product..

I do not know anything about the IGES standard so I can't comment, it does sound like the same old same old BS

It's the unified field theory of CAD-CAM communications. There is so much money and prestige at stake that even the SME has been drawn in and is a major sponsor and promoter. They made a VIDEO TAPE to promote an UNFINISHED STANDARD. There's a LOT of jobs at stake at SME.
