quarry carving coefficient seeger

Good morning to all, I have a doubt about the seeger ring quarry. I did some research and catalogs that the tree quarry must have sharp edges. the problem that I pose is how to assess the factor of carving relative to this quarry as the diagrams available both for torsion and for bending for a shouldering all refer to the r/d ratio with r ray of bottom quarry. if however there is a live edge r tends to zero and the kt tends to infinite. I wonder how to approach the problem.
Can you pick up the seeger quarries?
If you can't tell how I can assess a carving coefficient?
 
look at the site of the nits on the page of seeger, there is also a page dedicated to calculations.
no tool is perfectly sharp, it would break by ruining the cut. look on the sandvik website the rays of the truncators

Thank you for the answer. on the site of the nits as recommended by you I found what I attached.
we talk about fitting the quarries with 10% of the thickness of the ring. the suggested cutting coefficient however indicates it for a specific material. In my case, I have an aisi 304 for the tree.
Can I refer, however, to the carving coefficients proposed by the site ?
or will it change depending on the material? (although it seems strange because the available diagrams for shoulders refer only to the geometry of the shaft and not to the material)
and another question is: are these carving coefficients valid both torsion and to bending ?

the type of material affects you only on the possibility or not to realize the quarry with a certain tool (and therefore with its connection rays).

by definition kt does not depend on the material and does not depend on the scale (in fact the graphs report reports as r/d and d/d).
 
However on the peterson maybe there should be charts that might interest you. Have you tried to take a look?
kt depends only on geometry.
 
As they told you, all the truncating tools have rays on the two edges and those will be the rays on your bottom throat.

the chart that put you volaff has nothing to do with the goggles of the seeger, but the chart is this here for traction/flation:Screenshot_20220122_074150_com.adobe.reader.jpgand the one torsion:Screenshot_20220122_074538.jpgthe material must be evaluated if we make a dynamic fatigue test, where a considerable number of coefficients are evaluated.

thank you very much for the answer and for the material loaded. I was looking for this.
Can I ask you where you found these graphs (reference text or website)?
 
as we used to say or colleagues, we have the best book on the market for analysis: peterson’s stress concentration factors - 3ed.....now there is also the 4 edition.
