I have seen "chamfer" used to mean dulling a sharp edge, as in making telescope mirrors.
The etymology is also interesting:
chamfer
n.
5Fr chanfrein < OFr chanfraindre < chant fraindre < L cantum frangere: see CANT2 & BREAK6a beveled edge or corner, esp. one cut at a 45U angle
vt.
1 to cut a chamfer on; bevel
2 to make a groove or fluting in
