surface finish

English

surface finish (plural surface finishes)

(engineering) The quality of a surface, in terms of its roughness, microscopic pattern (lay) and macroscopic pattern (waviness).
- 2013, N. Dowling, Mechanical Behaviour of Materials, page 485
  If the surface finish is rougher that the polished surface of a typical smooth test specimen, the long-life fatigue strength is reduced.

Typically the expression good surface finish refers to a smoother surface finish, though smoothness is not always a desirable quality.
