Hurco Turning centers-Who's got them?

[Philabuster]

The Fanuc and Haas uses R and C for rounding and chamfering respectively on both, mills and lathes.

Some Fanucs would use 'C' for chamfer and some had to use 'K' for chamfer. I have no idea why the change, but this is Fanuc after all.

IIRC, the intended chamfer direction was also determined by designating a positive or negative value with the C or K. This is similar as you need to specify a positive or negative I or J value for G2 or G3 moves.

Lathe program turning a 2" step on a shaft with .1" chamfer on the nose:

G0 X1. Z0.1
G1 Z0 F.005
X2.0 K-.1
Z-1.0R.2
X3.

Auto any-angle chamfering. I know on Okuma controls it's a G76 that is defined by a K-word. Couldn't tell you what a Fanuc uses.

Truth be told though, I never liked using it. I've always preferred to just write out the individual points instead. Call it me being stubborn and doing things the hard way. (Just like G-coding instead of conversational... ) one benefit to programming the individual points or chamfers and radii, is that I typically slow down the feedrate on the smaller features to give a better "resolution." When using a .01" feedrate, a .03" chamfer only gets 3-turns of the chuck to generate the chamfer. By cutting your feedrate down for those smaller features, you get more definition. It might not be a big deal for a chamfer, but it means more on small convex radii.

Dunno when Fanuc implemented it, but mid 90's Haas did auto corner and chamfer on 90 deg. intersections, and since sometime in the early '00-s they do that on any angle
intersections.

My 81 6T has this feature, but only on right angles.

That's an awesome point.!

This is a video for DXF transfer in a mill. My lathe has not been delivered yet and I was looking for a DXF transfer on a lathe. Do any of you hurco lathe owners have the DXF function on your lathe?

I do.
It works almost the same as the mill. But you then have to enter, the entry and exit face or turn paths. I use it a lot on the mill and lathe, my only complaint is each time you select a line it should highlight in a different color.

Here's a little sneak peak fellas! I received our new Hurco TM8i last week. Finally! More to come on that.

Here it is!

Great looking Machine. I actually like that darker color. I would love to see some video of it running when you get a chance.

 

[Edster]

That's some collet rack you got there. Oh wait...there's a nice lookin' lathe behind it.

How about a few more shots

Congratulations, I also like the dark color machines. Now lets see some more photos and maybe a video.

Congrats on the new toy. BTW, I do like the new color better now that you can see it contrasting with other things in the shop. I heard from my rep that there are heavy discounts on all machines still sporting the "Blue" sheet metal.
