AUTOMATED PRODUCTION LINES
1. An automated production line consists of a series of workstations connected by a transfer system to
move parts between the stations. This is an example of fixed automation, since these lines are set up for long
production runs, making large number of product units and running for several years between changeovers.
Each station is designed to perform a specific processing operation, so that the part or product is constructed
stepwise as it progresses along the line.
2. A raw work part enters at one end of the line, proceeds through each workstation and appears at the other
end as a completed product. In the normal operation of the line, there is a work part being processed at each sta-
tion, so that many parts are being processed simultaneously and a finished part is produced with each cycle of
the line. The various operations, part transfers, and other activities taking place on an automated transfer line
must all be sequenced and coordinated properly for the line to operate efficiently.
3. Modern automated lines are controlled by programmable logic controllers, which are special computers
that can perform timing and sequencing functions required to operate such equipment. Automated production
lines are utilized in many industries, mostly automobile, where they are used for processes such as machining
and pressworking.
4. Machining is a manufacturing process in which metal is removed by a cutting or shaping tool, so that the
remaining work part is the desired shape. Machinery and motor components are usually made by this process.
In many cases, multiple operations are required to completely shape the part. If the part is mass-produced, an
automated transfer line is often the most economical method of production. Many separate operations are di-
vided among the workstations.
5. Pressworking operations involve the cutting and forming of parts from sheet metal. Examples of such
parts include automobile body panels, outer shells of laundry machines and metal furniture. More than one
processing step is often required to complete a complicated part. Several presses are connected together in se-
quence by handling mechanisms that transfer the partially completed parts from one press to the next, thus cre-
ating an automated pressworking line.
V. Прочитайте пятый абзац текста и ответьте письменно на следующий вопрос:
How does an automated pressworking line work?
