Chapter 2 Careers in Machining Technology 15
There is little chance for advancement out of semi-
skilled jobs without additional schooling and training.
Most semiskilled work is found in production shops
where there are great numbers of repetitive operations.
In general, semiskilled workers are told what to do and
how the work is to be done. They are often the fi rst to
lose their jobs when there is a downturn in the economy.
2.1.2 Skilled Workers
A
skilled worker
has been trained to do more
complex tasks. Skilled workers are found in all areas
of material machining. Many skilled workers obtain
their training as an
apprentice
in an apprenticeship
program (on-the-job training while working with
skilled machinist), Figure 2-3.
Four or more years of instruction under an expe-
rienced machinist is generally required. In addition
to working in the shop, an apprentice usually stud-
ies related subjects, such as math, science, English,
print reading, metallurgy, safety, and production
techniques. Upon completion of an apprenticeship
program, the worker is capable of performing the
precise work essential to the trade.
In recent years, the demand for skilled work-
ers has grown tremendously. Workers entering the
fi eld can receive their training through the armed
forces, Figure 2-4, or in career and technical education

manual lathe. The coursework they complete can be used
toward obtaining National Institute of Metalworking Skills
(NIMS) credentials.
