The machine shop teaches exactly how iron 6'f the various
kinds may be chipped, filed, turned in the different lathes, or cut
down in the planer or shaper.
.
The,construction and working principles of these machines are
essential to- all engineers and can only be learned by familiarizing
one’s self with the machine ds it works in the shop. Of xburSe,
every shop may have machines designed for the same work of
different make but the general construction and working principles
of all of them are based on the same plan. In their operations in the
niachine-shop it iS Often necessary to make a special tool for a cer
tain kind of work this is accomplished in the forge Shop. In the
forge shop, too, are produced m any^f the. machine parts that are
subjected to greater* strains than can be withstood by the cast iron-
of the foundry, these, must be Of steiel forged to shape. The tem
pering of cutting todls and told chisels is an everyday problem to
fhe engineer. This problem is Solved‘Scientifically, as well as prac
tically in the- forge shop. The welding of iron and steel is also
learned at the iotgfe.
