limit di tornitura

[vale79]

Hi.
someone remembers the formula to determine the maximum turning diameter in a round (of brass) to not create excessive stress in the material?
in practice we build these turned components, the walls are thin (in the order of 1-2 mm) and not uniform, i.e. there are thinner parts of others and parts with holes, carvings, etc. it never happened that they broke into normal use, while a short time ago they were used on the ships and they were literally broken, probably because of some vibrations that we do not know the characteristics. There must be a formula to determine how much material I can remove from the inside of a round, so I try from that and then maybe the increase.
Thank you.

Hi.
is interesting is what of the thickness limit of the brass
obtained by turning

on the market there are tubes that also arrive at 0.5mm of sp.

and even something less

in your case cannot depend on the quality of the brass
generically divided into three categories
hard-semiduri-hard springs

Thank you very much

Hey, shiren!
thanks for the information but the tubes so thin are not made for extrusion usually, if the brass is extinguished. I start from a full tondo uni cw617 or cw614, but the formula I meant on the ability to undergo processing is applicable to all materials.
for info with the raw brass also make lamine of 0.1 mm.
Thank you.
That's right.
