Frequently Asked Questions (FAQs)
1. What is surface roughness comparator?
Surface roughness comparators are used within industry to measure or verify the as-manufactured surface finish (roughness) of a part or assembly. Comparators are selected and used based on the manufacturing process used to create a particular surface finish.
2. What is the meaning of surface roughness?
Surface roughness is the measure of the finely spaced micro-irregularities on the surface texture which is composed of three components, namely roughness, waviness, and form.
3. What are the methods of measuring surface roughness?
There are several methods currently availafile to measure the roughness of a surface, these include contact stylus tracing, laser reflectivity, non-contact laser stylus metrology, scanning electron microscopy and compressed air measuring (Haywood, Heymann &• Scurria, 1989; Sander, 1991).
4. What is a Microfinish comparator?
The S-22 MICROFINISH COMPARATOR Surface Roughness Scale provides industry with established flat surface roughness specimens for visual and tactual comparison. It is used in specifying and controlling surface roughness when a product having the appearance of typically machined surfaces is required.
5. What is the difference between RA and RZ in surface roughness?
Ra is the average roughness of a surface. Rz is the difference between the tallest “peak” and the deepest “valley” in the surface.
