Acme vs Stub Acme Thread Form. Basic width of crest derivation.
Acme vs Stub Acme Thread Form. Basic width of crest derivation.
(OP)
I am trying to determine how the basic width of crest is derived in Stub Acme and Acme thread forms.
ACME:
Fcn= .3707*P
Height = .5*P
STUB ACME:
Fcn = .4224*P
H = .3*P
Does anyone know if/how these are derived?
See equations at bottom of this site. Just looking for how they were obtained.

Thanks!
