It's the art of adjusting most anything "truly square, or parallel, or
properly spaced, etc" as called for by the application at hand. Tools
used to obtain this include surface plates, gage blocks, levels,
squares, plumb lines, etc., and today, lasers. The degree of accuray
needed to obtain a good 'tram' depends on the application.

One use of the word is in setting up a steam locomotive suspension ...
getting all the driving axles parallel and spaced the same as the holes
in the siderods, and everything centered in the frame so the rods will
all line up with the crossheads and cylinder/valve bores, etc. When it's
properly 'trammed' everything will work smoothly.

The 'art' of adjusting the spindle truly square with the X/Y axis of the
table.
