Machining Vibrations - Industrial Context - Different Kinds of Problems and Their Sources

Different Kinds of Problems and Their Sources

Vibration problems generally result in noise, bad surface quality and sometimes tool breakage. The main sources are of two types: forced vibrations and self-generated vibrations.

  • Forced vibrations are mainly generated by interrupted cutting (inherent to milling), runout, or vibrations from outside the machine.
  • Self generated vibrations are related to the fact that the actual chip thickness depends also on the relative position between tool and workpiece during the previous tooth passage. Thus increasing vibrations may appear up to levels which can seriously degrade the machined surface quality.

Famous quotes containing the words sources, kinds and/or problems:

    I count him a great man who inhabits a higher sphere of thought, into which other men rise with labor and difficulty; he has but to open his eyes to see things in a true light, and in large relations; whilst they must make painful corrections, and keep a vigilant eye on many sources of error.
    Ralph Waldo Emerson (1803–1882)

    There are three kinds of lies: lies, damned lies and statistics.
    Benjamin Disraeli (1804–1881)

    Imagination is a valuable asset in business and she has a sister, Understanding, who also serves. Together they make a splendid team and business problems dissolve and the impossible is accomplished by their ministrations.... Imagination concerning the world’s wants and the individual’s needs should be the Alpha and Omega of self-education.
    Alice Foote MacDougall (1867–1945)
