The surface of a metallographic specimen is prepared by various methods of grinding, polishing, and etching.After preparation, it is often analyzed using optical or electron microscopy.Using only metallographic techniques, a skilled technician can identify alloys and predict material properties.. Mechanical preparation is the most common preparation method.

Abstract: In order to do the precision grinding of optical aspheric lens, it is essential to achieve high quality surface roughness. Experiments show that the contacting area between the wheel and workpiece in a grinding process is critical to influence the surface roughness for a fine grit size resin bonded wheel.
