materials and information.
The machines are means of production that use the forces nature of to
facilitate work.
From the point of view of functions, carried out by machines, it is
possible to classify all machines into the following groups:
a) Power machines;
b) Material-working machines;
c) Information (supervisory control) machines;
d) Cybernetic.
The power machine is a machine intended for conversion of energy
from one form to another (transforming any kind of energy into mechanical
one – the machine-engine, and vice versa – machine-generator).
The material-working machine is a machine for conversion of
materials. The working machines are subdivided into transport and
technological ones.
The transport machine is a working machine, in which conversion of
materials consists only in changes of their position in space.
The technological machine is a working machine, in which the
conversion of a material consists in changes of the form, location or
properties of a material or machined object.
The information machine is a machine for conversion of information.
These machines are subdivided into supervisory control machines and
computing ones.
The cybernetic machine is a machine replacing or simulating various
mechanical, physiological or biological processes, inherent to a man and
animate nature.
If the processes of energy or materials conversion are carried out
without direct participation of man, the machines performing such operations
are named automatic-machine devices.
The set of the automatic-machine devices connected with each other and
intended for performance of certain technological processes, is called an
automatic transfer line.
The set of the machine-engine, transmission, working machine and
supervisory control machine is called a machine unit.
It can be represented by the diagram:
