The shear strength is directly (proportional) related to the tensile strength of metals.
So to determine the shearing capacity of your machine...we simply compare the tensile strengths of the materials. The tensile strengths will vary according to the processing ie , annealed, hot rolled, cold rolled,...etc. But with some assumptions and "text book" values...you'll get a ball park idea.
Mild steel...say 1018-1020 may have a tensile of about 80KSI
Titanium is all over the board depending on the alloy and treatment...but lets say 135KSI which is on the high end and typical for 6AL4V.
so: 1018 @ 80KSI
6AL4V @ 135KSI
Comparing the steel to the Ti we see: 80/135= 59%. The steel strength is only 59% of the Ti.
So if you can cut 1" of steel, then you would only be able to cut .59" of Ti.
To correlate this to your shear:
14ga is .074" so the max Ti thickness is .074 X 59% = .043"....or about 18ga.
14ga steel = 18ga Ti
That's how I would do it.
Good luck,
