I have been getting various quotes for plasma cutting jobs. I
understand that there are disposables involved with tangible costs.

It occurred to me that there has to be a figure that would price out
the cost of a plasma cut perhaps in terms of dollars/inch of
cut/thickness of a given material, thus isolating the procedural costs
from others such as workshop rent, labor etc.

Has anyone done this?
