CNC mill, woodmill, etc…)" Happy April's fool! No, that's not why they are called mills. They are called mills because of the original mills that made flour. Because of those, anything else that was powered and rotated or that created something, possible by removing small bits at a time, were also called mills. Look it up. A similar thing happened in some dialects of Danish. My dear 88-year-old grand mother insists on calling a ventilator "en mølle" because it is powered, goes round, and does something useful. “as a result we call ANY machine which fabricates things (metal, wood, etc) with any precision a MILL (I.e.

I use calipers as well. I like the PCB scanning as documentation when the board or a full drawing may not be handy. I am doing a project where I don’t have any drawings for the board but I need to hack out a quick enclosure. I plan to print the PCB scan to scale and use it as a template to cut the holes in the enclosure. I could do this with calipers but It might be easier to use the scaled PCB scan. Great discussion..

In Europe, England, and many other countries, 1 MIL = 1 Millimetre or 1/1000th of a metre (yes we spell it meter---they dont).....which is where much of the confusion comes in, I believe. I lived and worked as an electrical engineer where i looked VERY foolish on MORE than one occasion (try to order #16 AWG wire in europe and see how far you get----in our language it means 16 wires laid flat side by side will measure 1 inch, but that is greek to them) until I wrapped my brain around it....the American version of MIL was first applied by American blacksmiths in the 19th century and was later adopted by the Society of Automotive Engineers (S.A.E.) who used it to define the thousandth of an inch; as a result we call ANY machine which fabricates things (metal, wood, etc) with any precision a MILL (I.e. CNC mill, woodmill, etc...). To aviod confusion in the future....always specify standard or metric MIL....for while we ARE discussing tiny fractions of measurements----the DIFFERENCE between a standard MIL and a metric MIL is HUGE!!!
