I took really bad with the turn screen as I was used to my mill screen, I just adapted my Mill Screen into a lathe screen and had the controls I wanted on it.

Yea it's kind of tough. The "`" key on mill is estop but does nothing on turn!

Hi
Thanks for the reply.
I think I got it figured out by copying the jog button on to the cycle screen. I understand the safety thing but for me the extra step of switching screens to jog the machine is a pain. The turn screens are very different from the mill screens  pertaining to work flow. I can jog all I want to in the program screen.

That is a safety issue of the standard screen set.

There are other screens, in the screens download page, where you can jog.
But I realy do not know what option can trigger that.

Hi Hood
It's absolutely in CV.  One thing I would mention is I'm handling huge amounts of code. The piece in the picture had over 500,00 lines loaded into Mach. As soon as I finish this piece I'll do some tests and post the results here. I'm going to cut that same section that has the chops but try it at a few different speeds and cutting strategies. I really need to get to the bottom of this.

Thanks
Derek

Yep CV tolerance is disabled. G100 Adaptive NURBS is enabled though. Not sure if this matters or not.

I'm about 99 percent sure that it's turned off but I'll double check tomorrow and let you know.
Thanks
Derek

Do you have CV Distance Tolerance enabled? If try without and see what its like.

Hi Hood
Yes it is most definitely made up of many line segments. but their deviation off of an arc is slight. I just cut out a section of the code on that area and inputted the coordinates as points. I then connected the points with a poly line. I fitted an arc to  that line and the deviation was less than .00003 Then I projected a line against the surface at the same z level as the tool path and the deviation was less than .003. This last measurement really doesn't mean much as we're concerned with deviation off of the arc as in a choppy cut. The tool paths all look nice and smooth as well.

Hi Hood
I'm using a horizontal finishing pattern. Round and round it goes!!!

Hey Eric I don't mean to hijack your thread but I think we're suffering the same type of problem.
Here's a pic I just shot of the area I'm talking about. This was cut with a .005" overlap at 50 ipm. You can easily see the chops on the right of the picture but they go all the way around the curved area to the left. When the curve goes straight the chopping stops. If I was to cut this at 100 ipm the chops would lead out at more of an angle.

Here's a link to the picture I couldn't figure out how to embed it in the post

I'm getting the same problems with my 3d files. anything that requires x and y movement together results in grooves in the profile. It's more noticeable the higher the speed. They aren't random either. I was cutting an angled curved wall with a .005 overlap and there was noticeable grooves running down the wall at an angle. It seems like the slower the feed rate the less angle on the grooves. I'm cutting another part with a slower feed rate and the grooves are running straight up and down.



I'm running servos by the way.
