Historically machinists have thought that obtaining data for grinding was simply a matter running tests on a given metal, collecting the data, and producing tables with the best feeds and speeds. However efforts to do just that found the subject was far more complex. ... downfeed increments as fine as 0.00004 inch (or 0.001 mm) may be needed.
Particulate matter 10 µm in diameter and smaller (PM-10) presents a health risk because the particles are fine enough to enter the respiratory system through inhalation and may become lodged in the tiny sacs of the lungs. Particulate matter 2.5 µm in diameter and smaller is called PM-2.5 and is a major
