A spotface or spot face is a machined feature in which a certain region of the workpiece (a spot) is faced, providing a smooth, flat, accurately located surface.
spotface. slip fit SFACE or S/FACE: spotface SHCS: socket head cap screw: A cap screw with a socket head (usually implying a hex socket, driven with a hex key. SHN: shown: See Part number > Symmetrical parts for explanation. SHSS: socket head set screw: A set screw with a socket head (usually implying a hex socket, driven with a hex key. SI
For a spotface, material is removed from a surface to make it flat and smooth, usually for a fastener or a bearing. Spotfacing is usually required on workpieces that are forged or cast. A tool referred to as a counterbore is typically used to cut the spotface, although an endmill may also be used. Only enough material is removed to make the ...

A Smith chart to calculate electrical impedance with no values plotted; although not a nomogram, it is based on similar principles. Like a slide rule, a nomogram is a graphical analog computation device. Also like a slide rule, its accuracy is limited by the precision with which physical markings can be drawn, reproduced, viewed, and aligned.
The horizontal alignment (or alinement in the United States) is done by using a predefined length of string line (such as 62-foot in the US and 20 meters in Australia [5]) to measure along the gauge side of the reference rail. It is the distance (in inches or millimeters) from the midpoint of the string line to the gauge of the reference rail.
