Post Processor for a Milltronics Lathe

[Anonymous]

Hi

Does anyone know of a post Processor that will post the correct NC post for a Milltronics Lathe ?

[Laurens-3DTechDraw · Accepted solution]

Milltronics lathe spec sheets say this:

Fanuc based G&M Code programming

So I would start with the fanuc turning.

How did you make out with the  post for milltronics lathe?  Thanks

I know this is kind of an old post, but I have a Milltronics lathe, and using the generic funuc turning post, it all seems to work ok except my threading feedrate defaults to .04 per rev. this is only during the thread turn Cycle (see below) I have my pitch set right on my tool and in my thread turning cylce in fusion, but when I post it changes on me any help would be appreciated.

case "thread-turning":
var r = -cycle.incrementalX; // positive if taper goes down - delta radius
var threadsPerInch = 1.0/cycle.pitch; // per mm for metric
var f = 1/threadsPerInch;
var codes = {A: 92, B: 78, C: 21};
writeBlock(
gMotionModal.format(codes[properties.type]),
xOutput.format(x - cycle.incrementalX),
yOutput.format(y),
zOutput.format(z),
conditional(zFormat.isSignificant(r), g92ROutput.format(r)),
feedOutput.format(f)
);

Well, that certainly is an odd one. Are you using the generic Fanuc turning post, or one that you saved and have been using for a bit?

I just downloaded the Generic Fanuc Post from the library, and yeah I have been using it, but this is the first time I tried threading with it.

Thanks

Are you saying that the current Fanuc turning post only outputs a feed of .04"? Just want to make sure I'm following correctly..

[Anonymous]

Yes sir, I dont think anybody's messed with it since I downloaded it.

I am working around it by camming my threads at the lathe then copy and pasting that part into my program.

here is what it looks like i am also attaching my actual post processor. 

here is my project

Well as an update, It is definatley in the post processor, I posted the same path for my Haas cl-1 lathe, and it posted correct. any Idea how to get the right feedrate out of the fanuc post?

[seth.madore]

@Anonymous I am not seeing this with the default Fanuc post that ships with Fusion. Can you share your post so I can see what is different?

I do recall a Fanuc post existing quite some time ago that would only give a 1mm feedrate. But that was years ago...

[seth.madore]

Ok; the issue lies in your post. It hails from 2013. I suggest moving to a more recent post that has received many updates. The latest one is from Dec. 2018

If you've done a lot of edits to this one to behave a certain way, I can see sticking with that one.

Hi

Do you have a copy of the latest post ??

[johnswetz1982]

If the post is not pone of the default ones included with Fusion updates, post are found in the post library at CAM Post Processors
