the Analysis of the information for management of separate figure of merit on ISO/TS 16949:2009

Let's observe, in what extent the maintenance of the information applied today at the Russian factories for management by process of its manufacture, influences a total quality of product and quality of management.

In the capacity of instances we take two production engineering of management:

- Maintenance of quality on the basis of the domestic standardised documentation with use of means of the alternative control (drawing 2.1);

- Statistical regulating according to demands ISO/TS 16949:2009 (drawing 2.2).

Controlled process instance - performance on stanochnom a work station of a replaceable production target on manufacturing of a kit of parts. The analysis circuit design is uniform (drawings 2.1, 2.2). In its left column the maintenance of process of performance of the task (sequence preparatory and manufacturing operations) is represented. Procedures of management are shown in the central part. The basic set of the documentary information is had in the right column.

In tejlorovskoj to a control system technical services of the factory have been obliged even before production target delivery to provide conformity of the rig and an equipment complete set to all demands to their accuracy, and also demanded quality of party of preparations. Three persons are involved in managerial process by quality on a work station - the set-up man (), the operator (), the controller ().

Preparation for task performance begins with adjustment technological

Systems, that is basings and attachings on the rig with demanded accuracy of a relative rule of all necessary modules - equipment and tools.

According to branch demands this procedure was regulated by the separate process chart of adjustment. The controller [84] has been obliged to confirm quality of performance of adjustment.

At machining on the multi-spindle, modular, grinding machines qualitative adjustment yet does not secure demanded accuracy of the first details. It is necessary to stabilise thermal deformations in technological system. Usually for this purpose it was necessary to process certain quantity of preparations according to the specification naladochnogo a discard. Actually a production target it is possible to consider performance as the controller of the validity of a series begun only after acknowledging from several details.

Thus, documentary demands and procedure of preparation of a production target create all basic conditions for manufacturing of planned quantity of suitable details.

Regarding management of process of performance of the task the industrial engineer has been obliged to regulate the periods of change of the become blunted tools. Within the limits of this cycle on maintenance of quality the set-up man carried out all necessary acts at own discretion: defined the quality check moment, sized up necessity of correcting or warning acts (additional adjustment for a size, change of the tool and other).

If the set-up man has sufficient experience and stimulirovan on exhaustion of suitable products, this circuit design of management quite provides performance of the installed demands to quality on the given work station.

Nevertheless in practice of the domestic factories about factors of lapses (the condition of the equipment, equipment, quality of preparations) frequently forced to pass absence of the fact sheet to the absolute control and to increase labour content of a production cycle. And during heading ISO/TS 16949:2009 specialists had to be convinced that
Absence of the information on an actual condition of process do not allow to proved to a user, that process copes sufficiently.

Statistical management on ISO/TS 16949:2009 (drawing 2.2) is carried out by registration and the analysis of the given measurements under in advance installed plot. Values of figures of merit of an autocomponent according to measurements are controlled by change of key control characteristics which define to the greatest degree magnitude of deviations of a handheld computer. For management of any flow process the standard demands to create a number of the new deeds containing the demands to procedures of identification and measurement of parametres (FMEA and SPC), and also to maintenance of objective data acquisition of measurements (MSA). But in these deeds depth of study of the maintenance of concrete production engineering is not regulated in any way. It is left to the discretion of the organisation. Therefore specialists will try to execute demands of the standard on former informational baseline. And level of study of deeds in the present compact factories is usually low. Let's observe, what results it is possible to expect in this case.

The main figure of management of process on a work station now is the set-up man / the operator as practically at all domestic factories controllers are devided out. Managerial process by a deviation of an individual handheld computer in the conditions of statistical regulating is presented in drawing 2.2. Adjustment of technological system should be carried out now according to the working instruction of the set-up man then it should be verified. If the industrial engineer has prepared the instruction hastily at handheld computer measurement the risk of revealing of a considerable deviation is great enough. Adjustment / should be corrected at once parametres of process and the instruction. Already on this step productivity of management is lost.

If during performance of the task after measurement of a handheld computer of / / details under plot SPC a deviation of value of it the handheld computer does not testify to presence of the special

The variability reasons task performance proceeds. If such reason is revealed, it is necessary to correct the most significant control characteristics of process under the management plot (drawing 2.2). If the set of these characteristics and an estimation of their significance are adequate, at correction verification the control card will confirm elimination of the special reason. Production target performance will proceed with the minimum delay. If in an estimation of adequacy limiting control characteristics of process and management plots / reactions the introduced error it is necessary to search again for the most significant reasons and to repeat correction. Manufacture can be shut down for a long time. To the full to verify the information on process, it is necessary to carry out again the analysis of the potential reasons which have been not considered in hastily made plot of reaction. Search of the reasons of instability in boundary lines of a full cycle of the ArQP-design (drawing 2.3) should be generally spent.

On each of its stages it is necessary to define at first concrete procedures in which there could be an omission of the control characteristic, the inadequate estimation of its significance or an error in magnitude appointment is admitted. After elimination of these white spaces it will be necessary to correct and the reaction plot.

According to the mustered changes it is necessary to correct or add also the maintenance of works at the subsequent stages AΓQP - the design. At last, it will be necessary to eliminate the reasons of emersion of an error in-process the specialist. Otherwise already at following measurement under plot SPC (the detail 2/) again will come to light a considerable deviation. As now industrially in view of deficiency of a time the system analysis is replaced with tryings of guessing of the potential reasons of instability, the result is quite predicted - absence of stable martempering.

It is necessary to recognise, that at the poor-quality information on the production engineering maintenance a control card it becomes far not the ideal tool of management. Besides it does not specify directly in the reasons of instability [17]. Therefore the main task of an interfunctional command on stabilisation
Processes - not to admit absence or an information foulness in an estimation of the significance key control characteristics of process in concrete situations. This condition also will be an assurance of productive management of the minimum duration of planning and performance of corrections.

To solve the given problem it is possible only at the expense of as much as possible careful identification and an estimation of actual characteristics of process at manufacture preparation. If it is not executed, at formally introduced SMK under demands ISO/TS 16949:2009 specialists of the domestic factories all the same will be forced to repeat alternative of acts on drawing 2. 3 [20]. In - first, it for a long time will distract a command on management of the design from sheduled work. Secondly, the risk of break-down of deliveries repeatedly increases.

The assemblage of potential errors and omissions during preparation of the information for SPC at our factories sets thinking on one aspect of productivity of management. On rezultam conducting of procedure FMEA it is the extremely important not to appropriate the handheld computer status to unfairly considerable quantity of parametres. To raise adequacy of their estimation, it is required to prepare in advance a complete set of documentary demands for all without exclusion to processes ZHTS AK.

To fathom, what information is required for as much as possible productive (ideal) management of process of formation of a handheld computer of an autocomponent in manufacture of a kit of parts on a work station, we will be defined in the beginning with the maintenance of a full complex of control characteristics, and with possibility of an estimation of the significance of their contribution to the measured deviation of a handheld computer.
