IV. You are going to read about flexible manufacturing. Find the answers to the following questions while reading:

significant departure from conventional manufacturing methods. An FMS

is a production facility consisting of flexible machines or work stations connected by an automated material handling system, all under the control of one or more computers.

computing machinesбhas made it possible to introduce a wide-scale automation of all branches of industry which gave rise to independent development of automation Аprocesses:

The FMS technology has a relatively brief history. The progress of

(a) Automated Data Processing (the appearance of Automated Control Systems and Computer-Aided Designing (CAD));

(b) Automation of Production Technology (the appearance of Nu- merically-Controlled Equipment, Computer-Aided Manufacturing (CAM) and Industrial Robots).

tomated lines and shops and at last Дautomated factories provided with flexible technology and computer-based artificial intelligence.

The development of FMSs began with the appearance of industrial robots, processing centres, microcomputers, computer-aided designing, etc. followed by the introduction of robotized complexes, flexible modules, au-

It seems almost certain that the main reasons for designing and implementing an FMS are the economic benefits of the system. They include first of all greater productivity which means a greater output and a lower unit cost on a smaller floor space.

И

It is possible to say that the FMS is the system where the time spent on the machine can be as high as 90% and the time spent on cutting can again be over 90%. Compare this to standalone numerically-controlled machines (NC), where the part from stock to finished item spends only 5% of its productive time on the machine tool.

70

High utilization of capital equipment in the FMS over that of standalone machines results in fewer machines being needed to carry out the same work.

High product quality is improved because the product is more uniform and consistent. This also leads to greatly reduced costs of rework.

СFurthermore, the ability of an FMS to produce whatever mix of parts is required on demand greatly reduces work-in-process time.

While an FMS requires fewer machine operators or none at all, the remaining staff (i.e. production engineers, computer programmers and

maintenance engineers) has to be highly skilled.

иThe main thing is that flexibility is characterized by the system’s ability to adaptбto change in the composition of the lots and of the machining processes and sequences which means that it is able to respond to changing market and consumer demands.

With correct planning for available floor space, an FMS can be designed for low production volumes, and as demand increases, new ma-

chines can be added easily to provide extra capacity.

Summing it up, it is possible to say that in all countries the introduction of FMS made it possibleАto greater increase equipment utilization and product quality, reduce the equipment idle time and cut down the number of attending personnel.
