Re: [CAD_CAM_EDM_DRO] Digest Number 1885

Hello,

I've got a few weeks ago a 4,13 Mega Pixel camera CASIO QV4000. It
has 1GB memory. I can take more then 500 pics with this memory card.
It has a very good flashlight. So a can take good fotos in workshops
of machines etc..

Chris,

Is this a VMC (Vertical Machining Center) or a bedmill or a
kneemill?
Is the "toolchanger" FULLY automatic, or a "quickchange" type?

And, What type of work do you intend to do with the mill?

Need to know a little more to give good advice.

Subject: Re: CNC Control software recommendations

Alex,

And you might have missed one of Jons' points:

Your concern seems to be your liability in the event the cnc
CONTROLLER code is changed.

Jon pointed out (correctly, IMO) that a crash of the GCODE program
by
an OPERATOR error can and will lead to a similar liability problem,
AND is much more likely than someone "hacking" the machine (which
both Ray and Matt explained could be protected at least as well as
existing proprietary systems).

Also, there is nothing preventing you from using the code and
protecting it however you see fit, and charging whatever you feel
your customers will pay for updates/upgrades... The fact that it
BEGINS as US govt. sponsored work makes it DIFFERENT from "open
source" (like linux). You may have to avoid using someones update to
the code, IF they have claimed Linux type "open source" licensing of
THEIR code.

And lastly, what is wrong with the idea of using "hardware" locks to
prevent the type of access which will ALLOW the changes in
controller
code you wish to avoid? This type of liability protection has been
used successfully for decades...

Hope this helps.

Ballendo

P.S. In our current legal system, the "lawyer" is going to look for
liability WHEREEVER the "pockets" are deep...

What is actually a good recommendation for a digital camera?
I want to use it mainly for the shop documentation and sending

The market is swept over with so many new models that you
cannot se the forest because of so many trees.

Hello Chris,
depending what you do with your machine and what commercial
aspect y look for. If you have batch production and safe sales
you will love the tool change option. For hobby use you will prefer
a quick change set up.
Good luck

Subject: Re: Re: CNC Control software recommendations


Hi Alex

Under linux, this is extremely easy to do not only for the cnc
program, but
also the entire operating system. Using conventional hard drives and
a
standard PC, I would partition the drive in to say four partitions.
Allocating just one for storage of the G code files and configuring
it as
Read/Write, all other partitions would be set for Read Only.
Setting the system to boot straight in to the CNC program without
using a
window manager will also prevent any unwanted programs (games,
system tools,
etc) from being run.

Now that most of the hard drive is Read Only, any software changes
or updates
will require a boot disk (either a floppy or CD). Even with these
simple
measures in place, tampering is still possible by someone with
sufficient
knowledge. Checksums can be used to validate the critical code, and
as the
MD5 checksums also include the date, any tampering will be
immediately
visible.

Regards, Paul.

P.S. Are you striving for historical accuracy? Have you looked to
the
makers of the "chain-mail" type shark suits for divers?

Hi,

I suspect not as I'm fairly sure the originals had the ends of each
ring
overlapped and forge welded together. This stopped the rings opening
up and
falling apart when they were poked with a sword point. The material
was also
somewhat smaller than 3/16" - 16 or 18 gauge wire. To get somewhere
near
automating the manufacture I would be looking at making the rings
one at a
time - cut wire to length off a coil, wrap it round a mandrel and
resistance
weld the ends together. The cunning bit would be to make the second
row
interlink with the first row and the third row interlink with the
previous
two before they are welded up. Then you are approaching real
chainmail -
each link having 6 others passing through it - two to the top, two
to the
bottom, one to the left and one to the right - all welded up so they
won't
pull apart!

That's the one I have. Paid $75.00 for it from value city (which
probably aren't around your
area). May be able to find it cheaper on the net. For the money, it
is a really decent camera.

Hi Ballendo:
Have you considered the difficulties you will have with flushing
for
this operation?
Wire EDM is a great process, but it can be a real bear when you are
trying
to cut parts of varying thickness.
(like the cross section of a round bar, or honeycomb materials etc
etc etc.)
Your advice regarding a quote from a commercial outfit is very sound
in this
regard.
Not a job for the faint of heart!!
Cheers

Marcus

Subject: Re: Re: New on EMC: How to set the steps per unit for each
axis? for metric

Hi Frank,

For metric units to work you need to change the Linear value to 1 -
it works
on my system without any trailing zeros. Also the INPUT_SCALE should
be set
to the right number of steps per millimetre and the OUTPUT_SCALE to
1/10th
of this number - so, if your stepper does 1000 steps per millimetre,
OUTPUT_SCALE needs to be 100 to make the system display correctly.
As for the system crashing, have you commented out the PERIOD
parameter -
put a ; in front of it - and, the MAX_ERROR and F(ollowing)_ERROR
values
will need increasing by at least 10 times.
HTH

Subject: Re: CNC Control software recommendations

Alex:

Let me comment regarding Control Software, since I know nothing of
the
industry. :-)

The use of open software may help any liability issues. It seems you
can
protect the system from tampering as well as any proprietary one.
The
advantage is in not developing the code, it is open source and, at
least
originally, developed by the US government. Therefore the liability
is
spread somewhat. As a machine mfg you can verify the code, with your
machines, as well as any you've written.

For this to work well, you will sell service rather than the
controller.
You will make $ supplying a package of optimized controller and
hardware, and keeping your customers systems up to date and working
well. The effort of optimizing EMC for particular hardware is a
large
task, particularly if tool changers, spindle speed control, coolant,
etc
are involved. The effort to understand and/or duplicate this work
will
create more loyalty than proprietary controller software.

As with linux, the advances of EMC as an open source package will
surpass what any one manufacturer will be able to achieve. Keeping
your
controller code non-proprietary and contributing to the open source
version will assure a better product than your company could achieve
alone.

Who did you say you worked for?
