El chaflanado o achaflanado es una operación mediante la cual se hace un chaflán, esto es, un corte o rebaje en una arista de un cuerpo sólido. Tales chaflanes pueden ser realizados en los cantos exteriores, por ejemplo en los extremos de un eje; o en aristas interiores, como las entradas de agujeros. Si se realiza un chaflán en la intersección de dos planos se obtiene una nueva cara plana y dos aristas rectilíneas menos agudas que la inicial. En cambio, si se realiza en el extremo de un cilindro, es decir, en la intersección de la cara lateral del cilindro con la base, lo que se obtiene es una cara cónica y dos aristas circulares.

A chamfer /ˈʃæm.fər/ 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.
