Simultaneous 4 axis moves on a lathe

Post by suntravel »

Maybe I am the first one using 4 axes with a lathe and Acorn....

but well, WMPG on lathe was only working with 3 axes, few days later Centroid made a new version of Acorn 4.80 working with all 4 axes usable on the WMPG. Thats why I feel very good with Centroid, fast and easy problem solving, big respect for this from me.

In this video its quite a senseless use of 4 axis simultaneous, but i think this shows off how cool and easy to use Acorn is.

G2/3 are anyway only circular interpolations of linear moves hard coded in the CNC, but if g-code processing is as fast and smooth like Acorn is, you can do this in g-code also ;)

The manipulation possible of the CNC only with g-code (macros) is in Acorn far ahead over most "big" CNCs like Mitsubishi, Fanuc or Siemens I know from my job.

So long bla bla, here it runs :

Very Interesting. It's good to see what can be done on a lathe. Is what you doing standard on industrial lathes or are you just thinking up things to try?

This is quite normal for CNC lathes...

Here is a type of lathes I am using in my main job:

Very impressive. I can't imagine how complicated it is to program one of those things.

I reckon there'd still be enough room in my workshop to fit one of those in....

Fricken awesome! the music in the video got me all pumped up, LOL OH and the machining to. :lol: :lol: :lol:
I can see why you went with the servo spindle setup. The versatility is endless, your work is so impressive!

Oh and I've been meaning to say i love the tool post on your machine, wish I went with something like that because I ended up locking the post off, no rotation for cutter angle changes.
