Machining History
machine timeline
Leonardo 1452 - 1519 (lapping machine )
Christiaan Huygens 1629 – 1695 - lens making - pendulum clock -
center of precusion.
Robert Hooke 1635 - 1703 - Pump building - Hookes law - many other
details
James Watt 1736 - 1819
Jesse Ramsden 1735 - 1800
Henry Maudslay 1771-1831 Early lathe
George Biddell Airy 1801 - Airy points - Airy stress function
James Nasmyth 1808 - 1890 Steam hamers - Locomotives -
astronomy - wrote the 3 plate method pre dates Whitworth..
Richard roberts 1789 - 1864 Metal Planer - influence of Whitworth
Joseph Whitworth 1803 - 1887 machine that could measure an accuracy
of about 2.5um. (1825-33?) perfected a scraping technique for
making true metal plane surfaces.
1817 - planning machine
Leon Foucault 1819-1868
1842 - 1919 Rayleigh John William Strutt, 3rd Baron Rayleigh - water
test - much more.
Leon Foucault 1819-1868
Maudslay - Nasmyth
Hall - acromat lens..
The often repeated bit that the 3 plate system came from Whitworth
(who did use it) is contradicted by Nasmyth who said it predates -
"I believe, a very old mechanical 'dodge'." Lenoardo has
drawings of a lapping machine - I think the 3 plate system came from
four milling machines. A riddle in history.
