Products and their component parts

In accordance with State Standard 2.101 - 68 productis any object or set of objects production, subject making on an enterprise. Products, depending on their setting, divide by the products of basic production (products, intended for realization) and auxiliary production (products, intended for the own needs of enterprise). The followings types of wares are set: a) details; b) assembly units; c) complexes; d) complete sets. Depending on a presence or absence of component parts of products divide on: a) unspecified (details) - not having component parts; b) specified (assembly units, complexes, complete sets) - consisting of two and more component parts.

A DETAIL is name product, made from homogeneous on the name and brand of material, without application of assembly operations.

An assembly units is product, component parts of which connect between itself on an enterprise by means of assembly operations (screwing together, stave, welding etc.), for example: car, machine-tool.

A COMPLEX is two and more specified products, not connected by on an enterprise-manufacturer assembly operations, but the associate operating functions intended for implementation, for example: production shop-automaton, ship, boring apparatus.

A complete SET is two and more than products, not connected by on an enterprise-manufacturer assembly operations and being a set products which have the general operating setting of auxiliary character, for example: complete set of awaiting-parts, complete set of instrument etc.

Any products can be made only on the basis of certain designer documents. Graphic and text documents, which determine composition and device of product and contain necessary information for his development, making, control, formal acceptance, exploitation and repair, behave to the designer documents. The different types of drafts behave to the graphic documents, circuitrys. In them there is graphic information about product.

Graphic documents are subdivided into the followings kinds: A detail design of DETAIL is a document, containing the view of detail and other information necessary for its making and control. Assembly drawing is a document, containing the image of assembly unit and other information, necessary for its assembling (making) and control. A draft of GENERAL VIEW is a document, determining the construction of product, co-operation of its component parts and explaining principle of work of product.

Overall Drawing is a document, containing the contour (simplified) view of product with overall, locational and joinings sizes.

Circuit is a document on which component parts of product and connection between them are rotined as conventional images or denotations. Text designer documents are documents, containing information about product as texts which can be presented in form tables, lists etc. To the text designer documents behave, in particular:

SPECIFICATION (document, determining composition of assembly unit, complex or complete set);

Technical regulation (document, containing requirements to product, its making, control, formal acceptance and delivery, which beside the purpose to specify in other documents), and also different LISTS, TABLES, etc. using for development, in a production, exploitation and repair of products.

State Standard 2.103 – 68 divided designer documents into design and detail depending on the stages of development.

Preliminary design and contract designbelong to design project. The incoming in a technical project drafts of general views are contained by basic data for implementation of detail documents - specification, assembly drawing, detail design etc. Concordantly State Standard 2.103 - 68 the followings stages of development of designer document are set:

1. Draft proposalis an aggregate of designer documents, containing the analysis of different variants of possible decisions of requirement specification of customer, feasability studies of the offered variants, patent search etc.

2. Preliminary design is an aggregate of designer documents, which must plug in itself of principle structural decisions, givings the general picture of device and principle of work of product, and also information, determining setting, basic parameters and overall sizes of the developed product.

3. Contract design - aggregate of designer documents, which must contain final technical decisions, givings the complete picture of device of the developed product and basic data for development of working document. A technical project serves as foundation for development of detail designer document.

4.Detail designer documents is an aggregate of designer documents, intended for making and tests of pre-production model, adjusting party, serial (mass) production of products.
