Re: [Emc-users] Swiss Type Lathe-Turn Machine

[Dave Caroline]

If you look at an old swiss cam auto then the concept of interleaved
moves was exactly how they optimised the speed of the cycle.

On my Bechler the tooling is on separate slides with accessory live
axes opposite the spindle.

Sounds like a pain to set up.  

I think 2 separate controls running separate programs, synchronized with 
digital i/o, might be simpler and have more potential.

Considering that a Swiss Lathe is intended for making parts in the
thousands, it is probably practical to write optimised G-code that can
handle breaking up and interleaving moves.

Imagine a time-line of moves, you break things up into sections at the
points where any axis starts or stops and use G93 inverse-time-mode to
make the segments take the right length of time.

Re: [Emc-users] Swiss Type Lathe-Turn Machine

[Ralph Stirling]

I believe the Machinekit people have the LinuxCNC code reworked
to the point they can have multiple instances running together, but
they still have a lot of other rough edges.  For now, probably two
CPU's would be advisable.  The new option of running LinuxCNC on
ARM's, such as the RaspberryPi 3 makes this a reasonable proposition.
Two Rpi3's and two Mesa 7I90's would still be under $200.

Sounds like a fun project.  I've thought for a long time that a swiss
machine with a dead control but good iron would be a neat challenge
for LinuxCNC.

I have got a machine equipped with two spindles. Spindle 1 has gang tools which 
can move in X,Y plain (Y axis to select tool) and Bar comes out as Z axis. 
Second spindle is mounted on moving platform (table X2, Z2 axis). Two or Three 
set of tools are fixed on the side which can be used with spindle 2. X,Y and Z 
axis are independently working from X2 and Z2. The only synchronized move is to 
get work piece from spindle 1 to spindle 2 while both are rotating. The picture 
for the machine axis can be seen at
https://mega.nz/#!dJd00QAb!Nd0CIat6Rw4E1rVZAdN8QgfBWkcJqptRk8xossyA86Q



In my opinion the set up needs TWO independent interpreters etc. so that X,Y,Z 
and X2,Z2 can be independently running G-Code files.
Can someone suggest that LinuxCNC can handle this type of configurations or any 
other suggestion may be help full. The original control on the machine was 
MELDAS (Mitsubishi) and drives are analog Mitsubishi.

If you need truly independent motion, then that it probably correct. I
think that this means two independent PCs, though it _might_ be
possible to have two separate LinuxCNC instances with separate
shared-memory areas.

If almost-independent is good enough (and it might well be) then you
can consider breaking moves in one axis to start another axis moving.

LinuxCNC can drive up to 9 axes, but they do all move in a coordinated way.

Another possibility for things like a cut-off slide would be to
fire-off instances of the simple_tp HAL component.

Andy,

I misread the guide.  I installed the package with the live CD in section
3.4 and then went on to section 3.7.1, thinking I was supposed to do that
in addition, when I should have been done. I will just start over.  Thank
you for your time.

Did step 5 succeed? It seem possible that the system is refusing to
uninstall the currently-running kernel.

It depends on the vintage of the equipment, of your motor drives part number 
ends in 6057 or less, you have a analog +-10V drive which is easy to 
interface, but if your drives part number ends in 6058 or greater, you have a 
digital drive (PWM from controller, 2 analog current feedback channels from 
drive = tough to integrate)
