11.2 METHODS OF MEASURING SURFACE ROUGHNESS

 

· There are a number of useful techniques for measuring surface roughness,

  1. - observation and touch - the human finger is very perceptive to surface roughness
  2. - stylus based equipment - very common
  3. - interferometry - uses light wave interference patterns (discussed later)
