Hmmm, now I'm a little confused. Rich are you saying that the problem is with the simple threading wizard and Mach doesn't make those sort of moves on it's own for timing or anything else?

As for tool and coolant, the tool barely sticks out and I always use mist coolant. The chatter is just normal and I know how to get around it.

No problem, I wonder if I sped up the RPM so there isn't so much friction when doing internal. I notice when doing external I run at 700 RPM and about .01 and .015" per pass and they come out silky smooth. For internal I run 700 RPM and the same .015" per pass and the sides of the threads have patterns where you can see where it's chattering. On my 9x20 HF I have it working perfect but at higher speed I always get chatter from doing ANYTHING internal threads or just cutting, no matter what tool or bit I use, at least on aluminum. So I will try some different things. First slower with smaller cuts and then faster with smaller cuts and see what happens. I think the Gcode that the Simple Threading Wizard puts out is normal Gcode? So even if I wrote a threading program by hand Mach is still doing something on it's own for timing?

I understand that but I cut external threads all the time no problem. The problem is when cutting internal threads every few cuts it'll do a tapered cut in air, but it doesn't clear the last few threads and chews them up, that's what I asking about, why this is happening and what I can do to stop it or add more clearance when Mach needs to do a test cut.

Hood, I ran a 10-32 external thread today and the plugin turn diag. Now it has not done the taper extra air cut on external threads for months only on internal. Anyway, the "highest variation during threading" was 7.69%. I'm not sure if that's the value you were looking for, let me know what I should be looking at to see if anything is going wrong. Thanks.

I got it, I'll try it tomorrow, thanks again. Have a haggis on me :-)

Thanks Hood, but what is the threading plugin diagnostic?

OK so for most of the threading I do I use the Simple Threading Wizard already in MACH and it works mos of the time perfect. One thing I noticed that has been happening all the time but never really noticed:

When I cut external threads every once in a great while it will do a cut above the threads, I assume that it's timing was a little off so Mach does an ancillary cut to make sure the time is correct, this cut is above the threads. When I do internal threads it does the same ancillary cut to check the timing but it's moving X at a taper and it doesn't clear the threads, it's actually messing them up. So my question is how come it does that taper move but hits the internal threads and ruins the them?

Well if you have any suggestions? I mean it only does it when it's doing a rapid move where one axis is long and one axis is super short. I do 3D all the time with no problems.

hmm, ok, well the problem gets solved by slowing down the rapids, so I think I'll just stick with that, thanks for the help.
