The basic concepts of technological processes Production
can be defined as set of all processes connected with transformation of raw materials
and materials in finished goods of the given enterprise. Process that part
of production which is directly connected with change of the sizes, the form or
properties of processed materials is technological. We should define technology
of stoljarno-mechanical manufactures as scientifically and almost well-founded
system of methods and receptions of processing of wood materials for reception
from them joiner's products. Detail name the elementary component
of a product, the form and which sizes are set by the product drawing. As operation is called the part of the technological process
which is primary unit of its division in given manufacture. As a workplace
understand a premise site where the equipment (machine tools, workbenches, adaptations),
materials and the stock, used by workers is definitely located at performance
of operations. Installation name the part of operation which
is carried out at one fastening of a detail in the machine tool or the adaptation.
Pass is the part of operation which are carried out at one moving
of a detail concerning the tool in a direction of giving (or the tool concerning
a detail and a case of item processing). Individual or individual
manufacture name such manufacture at which products are produced in insignificant
quantity, and repetition of release of these products specially is not provided.
Serial name such manufacture at which products are issued more
or less in large lots (series), and repeatability of a series in advance is provided. Mass name such type of manufacture at which products are
issued in a considerable quantity, continuously and for a long time, without change
of their design. Such manufacture at which workplaces settle
down as operation performance is called as is continuous-line, and the number
and productivity of these places are calculated in such a manner that transition
of processed details (or products) from one operation on another without a delay
is provided. Manual stream - the most simple form continuously-line
production. At it transfer of details from one workplace on another is made by
workers manually or by means of the elementary transport devices (склизов, rollers
and etc.). The stream with the distributive conveyor represents
the line of workplaces served by one general conveyor (conveyor), used as a simple
vehicle for transfer of processed details from operation to operation. For performance
of operation of a detail act in film from the conveyor on workplaces. The
working conveyor name the product line on which working operations over
details are carried out without them from the conveyor. The automatic transfer line is the higher form of mechanisation
continuously-line production, at it is automated not only transport of details
from one workplace on another, but also processing of details on each operation.
The general structure of technological process is approximately identical to all
stoljarno-mechanical manufactures. | |
