Working out of elements of informational-technological support of quality at an autocomponent design stage

According to [67] management of process of manufacturing of autocomponents it is carried out by an interfunctional APQP-command of the supplier. ISO\TS 16949 demands, that the supplier of autocomponents has provided quality management in all processes of life cycle AK.

However the gathered narrow specialists various a profile not in a condition objectively to size up solutions of colleagues without presence of the generalising information on full life cycle of an autocomponent. If it is not present, the command is unable adequately execute procedure FMEA. Preparation of deeds for manufacture approval, and also maintenance of sufficient depth of procaking of the information in a batch production will be besides, complicated.

In the domestic technological documentation the demand of documentary procaking of processes on full life cycle of an autocomponent is absent. Therefore it is important to structure at first this cycle in a total storage, and then to be convinced available documentation on all its components, to expel possible omissions and errors in streams of processes. For a basis of the analysis of life cycle we take quality definition
G.Taguti: «quality of a product is defined by volume of losses which are born by a society during term of its existence» [10].

In other words, for each process of life cycle of a product it is important to define demands to which it should match. When demands are formulated, process of their performance should be observed as this or that production engineering. All life cycle of the artificial product created by the person represents a stream of production engineering. Important as much as possible full to present the information on procaking of all processes in this stream [18, 19].

The structure of production engineering of life cycle can be only hierarchical: components of contiguous underlaying level should be enclosed in the maintenance of process of overlying level (drawing 3.1). As top level elements we will consider stages. Elements of contiguous underlaying level of each stage are routes. Each of them in turn consists of a stream of production operations (industrial, transport, warehouse, control). In operation structure also structural elements consistently deposit, major of which are technological transitions.

In table 3.1 the instance of structurization of life cycle of a detail of type an arm for assembly fastening to a lorry frame is presented.

At the overhead hierarchical level in the maintenance of life cycle of a detail in the capacity of components following qualitativly various basic stages are gated out:

1. Manufacturing of a material of a separate detail of an autocomponent (in this case it is handsheet);

2. Detail manufacturing (the elementary autocomponent);

3. Detail turning on in composition of knot, the assembly and a final product;

4. Application of a detail as a part of the car;

5.1 preparation of a material of the completed detail upon termination of useful term of its service to a reuse;

5.2 salvaging at impossibility of use (storage in an environment).

Also at each stage autocomponent unit consistently passes in table 3.1 through a number of specialised routes. They are grouped as follows:

- Industrial (appointment itineraries),

- Transport,

- Conservation of characteristics AK in demanded limits,

- Verification of characteristics (acceptance inspection, tests).

At a stage «manufacturing of a material of a detail» the itineraries providing manufacturing of metal and reception of handsheet are gated out. Transportation for limits of ambit of manufacture of the organisation should be issued a separate itinerary.

At a stage «detail manufacturing» irrespective of the manufacture organisation modern production engineering switches on itineraries of mechanical, thermal and finishing machining. Itineraries of long storage in a warehouse necessarily deposit.

At a stage «detail turning on in composition of knot and a final product» is expedient to gate out following itineraries: storage as a part of delivery party in a warehouse of factory, storage in a warehouse of assembly manufacture; assembly assemblage; assembly tests; delivery to a main plant, assemblage of a product, product test (regarding those regimes which are provided with a detail), finished article storage on a platform of the manufacturer, product delivery in the centre of sales, preselling preparation, delivery for the customer.

At a stage «use of an autocomponent as a part of a product» will be necessary to gate out routes according to conditions

Car applications, for example, functioning, maintenance service, diagnostic. It will allow to analyse much more in detail the reason and aftereffects of potential defects to arrange in sequence FMEA the analysis, to raise adequacy of its estimation.

On the basis of the offered circuit design the APQP-command forms the list of itineraries.

Further the command of specialists of an interfunctional APQP-command provides formation of the compound map of a stream of routes of life cycle AK. In it for each itinerary full reference data should be specified in regulating deeds (requisites, commissioning date, the deed name) (table 3.2). If necessary it is required to request copies of deeds on the paper carrying agent or in electronic form, containing the demanded information on an itinerary. Formation of such system baseline of deeds interfunctional APQP - a command in many respects depends on interest of the factories in achievement of the purpose of the design.

As a result of this work even the given information will allow not only to present to the narrow specialist visually a complex of documentary demands to the finished chain of routes of processes of life cycle, but also to be knocked down in their maintenance.

In addition specialists of an APQP-command need to be defined with designation streamlining (foliations, codings) itineraries. After all as a unit the technological documentation can foliate only operations. Thus, in the deed there is an important identification sign - foliation of itineraries.

The card of a stream of routes of an autocomponent also allows to differentiate univocal zones of responsibility of owners of each separate route so - will expel omissions in management of a stream of itineraries. Alignment of the maintenance of deeds on a stream of itineraries becomes much easier. The card of a stream of itineraries will essentially facilitate also

Command work on formulation of the preliminary catalogue of a handheld computer - the major new element of initial data for working out of processes. It becomes a reliable basis for preparation of a card of a stream of the processes, given as a unit RRAR (drawing 3.2).

Besides, ordering of itineraries and presence of their card of streams with bolshej reliability can show to a user, that the interfunctional APQP-command of the supplier really provides controllability with process of life cycle of an autocomponent. For presentation it is expedient to present a card of a stream of itineraries of manufacture in addition in the form of the circuit design directly on grading of floor spaces of the supplier to give the most objective representation about the flow process maintenance [18, 19, 25, 103]. At last, the given card or the circuit design can be used as the navigator for achievement of uniform perception of the maintenance of processes of life cycle of an autocomponent by all participants of an ArQP-command. Marks of adoption by specialists of erroneous solutions or omissions as a result will decrease.
