Douglas Harper's Etymology Dictionary
chamfer

c.1600, "small groove cut in wood or stone," from Middle French chanfraindre (15c., Modern French chanfreiner), past participle of chanfraint. The second element seems to be from Latin frangere "to break" (see fraction); perhaps the whole word is cantum frangere "to break the edge." Meaning "bevelled surface of a square edge or corner" is attested from c.1840, of uncertain connection to the other sense.

Chamfer

A chamfer is a transitional edge between two faces of an object. It can also be known as a bevel but connotes more often cutting and is more often 45° with respect to the two adjoining faces. If the un-chamfered intersection of the adjoining faces would otherwise form a right angle, 90° as is most common, the chamfer will typically be uniform and pitched at 45° . A fully chamfered square interior would thus be octagonal. (By contrast, a fillet is the rounding off of an interior corner, and a rounding of an exterior corner is called a "round" or a "radius")

"Chamfer" is a term commonly used in mechanical and manufacturing engineering. Special tools such as chamfer mills and chamfer planes are available. In tile work, or furniture such as counters or table tops, an edge or arris that has been eased by rounding instead of chamfering is called a bullnose. Where a chamfer does not go to the end of the piece, but "lifts out" in a smooth curve, the end is called a lark's tongue.

In non-aesthetic uses, chamfers are necessary in parabolic glass mirror manufacture and desirable in certain printed circuit boards.
