Surface roughness comparators are used to establish a basis for the feel of the roughness of
surfaces on manufactured parts to a known roughness value. In this course, you will gain the
mastery required to accurately measure with a surface roughness comparators.
By the end of this course, you will be able to
• Identify the characteristics of surface texture
• Identify a surface texture symbol on an engineering drawing
• Identify the components of the surface texture symbol
• Compare the roughness of a surface of a part to a surface roughness comparator
