Computer control programmers and operators
use computer numerically controlled (CNC)
machines to cut and shape precision
products, such as automobile parts, machine
parts, and compressors. CNC machines include
machining tools such as lathes, multiaxis
spindles, milling machines, laser cutting,
water jet cutting, and wire electrical
discharge machines but the functions
formerly performed by human operators are
performed by a computer-control module. CNC
machines cut away material from a solid
block of metal, plastic, or glass known as
the work piece to form a finished part.
Although they may produce large quantities
of one part, precision machinists often
produce small batches or one-of-a-kind
items. They use their knowledge of the
working properties of materials and their
skill with machine tools to plan and carry
out the operations needed to make products
that meet precise specifications. This
program consists of one short certificate. |
