Hello, I noticed you have the P value in the second line wrong, is P900 in that case not P600... (Diameter - core dia)/2. In that case (20-18.2)/2=0.9 so that give us P900
R value in the 2-nd stroke has to be a tapered (x-offset of start thread) parameter. If it is straight thread just R0 ... Very useful option which I think, has to be in your beautiful explanation.
So interesting and clear but P value should be big diameter minus final or smallest diameter divide by 2. Which gives 900 in this case instead of 600. Proof: 0.9*2+18.2=20 big diameter.
I have a thread to make and it have a groove where the thread stops kinda like an undercut but its where the z stops before the x moves to clear. is there a way to do that with a g76.
wrong,,,, p value on second line should 0920 as depth of 1.5 thread is .920 multiply this by 2 (1.84) subtract that from thread major dia (20) gives 18.16 which should be your X core dia, this is easy to find in any thread spec, or just multiply the pitch by .6134 to give you your depth

Thanks you helped me find out what was wrong with the first cnc metric thread video

Fantastic video
explanation are very concise. thank you

Doesn't core diameter and thread height conflict with each other ?
my old machine doesnt have p value. thank you for the tutorial though. when i get something more modern I'll be bacl

Is the first R for finish allowance valued in microns as well?
I think that "P" value is an upside-down 9 and not a 6?
Or you can use after g76 a modal g92 for finish

After memorizing this video meticulously... My lathe is too old for the g76 code
Did you try the single line one?
@@sonzai9441 no, is that a thing ? I checked and my lathe has g76 listed in the OS so maybe that's it
@@MechInvent yes, just used it today on a 80- ies mori seiki
Hey Mark, your pronunciation is a little hard to understand some words. TH-cam can not translate your speech into captions in a perfect way.
