Metallography and Metallographic Microscopy | Anderson ...

Metallography is the study of the structure of metals and alloys. Metallographic analysis can be used as a tool to help identify a metal or alloy, to determine whether an alloy was processed correctly, to examine multiple phases within a material, to locate and characterize imperfections such as voids or impurities, or to observe damaged or degraded areas in failure analysis investigations.

Microscope History | Microbus Microscope Educational Website

By grinding and polishing, he was able to make small lenses with great curvatures. These rounder lenses produced greater magnification, and his microscopes were able to magnify up to 270x! Anthony Leeuwenhoek became more involved in science and with his new improved microscope was able to see things that no man had ever seen before.

Grinding - Castle Metals Site

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge, and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.).
