Thanks for your reply.

As I stated, I know Centoid has a conversational mode. When building
a multipart project it is useful to be able to develop and assemble
all the parts in CAD, then move them to CAM. For cylindrical parts
it just makes it easier to be able to generate G code from the
CAD/CAM package. Also as pointed out some parts, with spiral features
are very difficult to produce in conversational mode.

Hello  @clpeDev,

I have AC95  (Y4B 091 000), the machine is a EMCO PC MILL 155.....do you experience about this?

Thanks

Now as I'm new to the Emco CNC line, take what I'm about to say with a grain of salt.
I have a PC 55 lathe working with an old computer running W98 and WinCAM.
My fear is when the PC ultimately gives up the ghost replacing it with a new computer that
has an ISA/EISA slot could be fairly expensive in the scheme of things. Several companies
manufacture motherboards/machines with this legacy capability. Cost $800 to $1500.
An alternative is retrofit/conversion. There are several companies that have boards/kits to
do this. Before acquiring my PC 55 lathe, I researched this option in case the machine was
incomplete or the electronics had failed. The core iron of these machines is fairly bulletproof
and should last for decades.

I was most impressed with the Centroid Acorn product. Centroid has an extensive history of
providing control electronics/software for large CNC machines. When one compares the cost
of converting the machine to the Centroid product, steppers/syncros, NEMA 17 adapter plates,
motor drivers, Acorn board, spindle encoder, use of an existing Windows 10 PC and upgraded
Centroid control software the cost falls around the upper limit of purchasing a new PC with
the legacy ISA/EISA slot. This does not take into account what one could recoup by selling
the Emco control electronics that are replaced in the conversion including the RS422
communication board.

The only problem with this approach is finding a CAM package that has a Centroid Acorn
postprocessor. I understand, maybe wrongly, that Fusion 360 has one. However, with the recent
licensing change from Autodesk, the hobbyist (free) version of Fusion 360 does not allow
for tool changes. One has to assemble the G code from each operation manually. Also, I have
found Fusion 360 to be a bit enigmatic at times, but I'm not a CAD/CAM professional. I have an
educational license for Solidworks, but have not been able to locate a Centroid Acorn
postprocessor for Solidworks CAM yet. I think there are other Linux options, but I have
not had time to explore those yet. And yes I know you can use the Centroid software in
conversational mode.

My long term plan is to convert to the Centroid Acorn controller both for a PC 55 lathe
as well as a PC 55 mill.

Any comments are welcome - just no flames.

Tim

Re: Emco PC Turn 55 Lathe G Codes

Tim Boan
 

Yep, WinCAM. Thanks, you confirmed my fears. I do have the Fanuc 0 control panel that's uninstalled.
As I noticed in the documentation for that, there is a list of supported codes. I guess I'll get around
to trying to install that. Fortunately, I think I have all the installation software diskettes.

Hi. Does anybody have a list, or can point me to the documentation, of the supported G codes when the lathe is run in the Emco55 mode.
I know buried in the Software Manual it says DIN/ISO 66025, but that seems a bit to inclusive.
Thanks

Chris, the benefit of updating to a modern control will be the ease of which you are able to interact with the user interface. The ability to load your parts via USB thumbdrive, and better G code compatibility.
I have retrofitted about a dozen of these machines. The users have been very happy with them. But you can expect to spend as much or more than you paid for the machine. Because it has a tool changer on it, that made the buy a little better.

Good luck with your project!

If this machine is not for sale, but for myself, I recommend upgrading it to modern control systems.

Your machine has AC 95 installed. You need a PC with an ISA slot, Windows 95, MS disk, ISA card RS422/CAN

Hi, this machine is just down the road from me in Sterling Virginia (about 20 miles to the southeast). I was going to bid at $800
and use it for spare parts for my recently acquired PC 55 lathe. Without a PC with and ISA slot and the R422/485 interface
card it's kinda useless without complete retrofit. I'm midly surprised it went for as much as it did.
