Milling (machining) - WikipediaWhile endmills and the other types of tools available to a vertical mill may be used in a horizontal mill, their real advantage lies in arbor-mounted cutters, called side and face mills, which have a cross section rather like a circular saw, but are generally wider and smaller in diameter.
AWG and Circular Mils - PDHonlinecircular mil is a unit of cross-sectional area that is equal to the area of a circle that is one mil (0.001 inches) in diameter. A circular mil or c.m. is therefore equal to π * ( 0.001)2 / 4 = 7.85 x 10-7 square inches. The advantage of using the units called circular mils is that the cross-
How to Calculate the Resistance of Copper Wire | Our PastimesK = 10.4 (a constant, ohms per mil foot for copper) A = cross-sectional area in circular mils R = resistance of conductor in ohms. For example, to calculate the resistance of a 250-foot #10-gauge copper wire, ply length by the constant 10.4, then divide by the cross-sectional area for #10-gauge wire as the following steps show:
Mills Longitudinal Study: ResearchCurrent and Ongoing Research. The Mills Longitudinal Study has focused on issues most relevant to the age of its participants, starting in their early 20's and following them through middle age, into early-old age. We are now in a particularly good position to study the new "older person."

What Is the Cross-Sectional Area of a Wire? | ReferenceWhat Is the Cross-Sectional Area of a Wire? The cross-sectional area of a wire is the size of the face of the wire if it was cut vertically perpendicular to it's length. The cross-sectional area is independent of wire length and is typically uniform across the entire length.

CM - Circular Mil Area - Engineering ToolBoxThe circular mil is a unit of area used especially when denoting the cross-sectional size of a wire or cable. A circular mil is the equivalent area of a circle whose diameter is 0.001 (10-3) inch, or approximately 0.7854 millionths of a square inch.; Mils of circular wire or cable can be calculated as:

Conductor Size | Physics Of Conductors And Insulators ...Although a square or rectangular cross-section is very common for busbar shape, other shapes are used as well. Cross-sectional area for busbars is typically rated in terms of circular mils (even for square and rectangular bars!), most likely for the convenience of being able to directly equate busbar size with round wire.
