Hi all,
While browsing the interwebs I came across this new paper "Performance
analysis of cross–coupled controllers for CNC machines based upon
precise real–time contour error measurement"
http://www.sciencedirect.com/science/article/pii/S0890695511001659
or
http://dx.doi.org/10.1016/j.ijmachtool
A quick google turns up the MDSI page at http://www.mdsi2.com/ which
states "In 1993 MDSI revolutionized manufacturing with OpenCNC® - the
world’s first open–architecture, CNC software not requiring any
proprietary hardware". Sounds to me like they mean "Open" in a very
specific and limited sense.
what is the meaning of this term 'open' that is used?

Hi all,
While browsing the interweb
Yes, some of the early(1993-1994) EMC papers from NIST also use the
"open-architecture" term. A couple are referenced in the wikipedia
article:

Gentle persons:
The road to nirvana, or hell, depending on your point of view, is
littered with slogans.
The wikipedia article on "open architecture" isn't very good. The one on
Webtopia is better http://www.webopedia.com/TERM/O/open_architecture.html

Anders,
Will Shackleford went on to work for MDSI. He was there circa 2005 when I
visited for training, but at that point I had not realized who he was.
OpenCNC was the product that indirectly introduced me to EMC and the reason
I ported the VTI driver from EMC to EMC2, as that was the board we we
I think when they say 'open' they mean open your wallets! Package starts at
$7000!!

Gentlemen,
I have one Cinci 5 axis controlled by MDSI's OpenCNC ver 3.0 control
software and Qnx 4.25 rtos. I installed the control in 1998. This machine
runs reliably every day.
I put OpenCNC on three Cinci 5 axis mills. One machine physically broke. My
EMC2 Cinci was OpenCNC until I put EMC2 on i
I thought Will was still at NIST. He is currently
listed as staff there.

Steve,
I am not sure how to confirm it, short of writing someone at MDSI. I just
recall that after I started working with EMC I came across his name and
thinking "holy you know what", that was one of the guys at MDSI. Of course
at that time I wasn't going to ask because I did not want them to know
