3.1 THE PURPOSE OF DATA SHEETS

It is obvious that the elimination of waste or overloading of any of the resource industry, including materials, machines, methods and money as well as manpower depending on appropriate planning of the use of available resources and their efficient control during production phase, selling and their after related activated. Planning and control are essential activities to the rapid expansion of industry and employment.

Control requires a particular pattern of activities to operate properly in a dynamic and imperfect world. It is difficult to improve because the behaviour of pattern of events difficult to understand and also because control have the emotional overtones associated with love of power and fear of being dominated. Therefore, it is essential to have a transferable for objectives analysis, as otherwise subjective emotions will present clear thinking on the desirable use of Techniques. It is for this reason that specific Data sheets are reputed to introduce a diagrammatic rotation for recording and studying planning and control inspection to shows that without such a representation any decision and discussion of control is obsortive.

The Data Sheets thus aims at establishing a framework for the study and important of planning and Control so that working group which comprises of senior management technicians, supervisor, foremen, trade unionist, operations etc. have a common termination and set of ideas with which to analyse and discuss problems and install fruitful improvement.

3.2 THE PRODUCTION ORDER

The Production Planning which constitutes the paper work leads finally to be in issuing the production orders. This is evidently very tedius and complicated matter preparing the production orders but essentially to be maintained. Such system cannot be application to other industries “as it is” because it is having a bearing of various aspects like size, and nature of manufacturing unit. With appropriate modification to some what extent it can be copied down from other one.

Purpose :-

1. To pass information to everyone concerned.

2. To authorise.

3. To start the control system.

4. To provide basis data for evaluation of performance like schedule, quality and cost wise.

Procedure :- To formulate the production and

1. Obtain all specifications like drawings, materials quality, quantity.

2. Outline the alternative methods of production and fix up the best one.

3. Determination of sequence of operations using process chart.

4. Find out the operation time required.

5. Prepare operation sheet with above data.

6. Work out production master program.

7. Prepare route cards and operation sheet.

8. Check out the available time on machine and prepare schedule of timing of production.

9. Machine loading charts for work distribution.

10. Prepare job cards, materials requisition cards, tools and drawing requisition, inspection and alt other belonging.

Process charts :-

A process charts shows all the operation and the inspections of the process or procedure in their time sequence and the material or parts entering the process. The process chart is usually drawn at the commencement of the investigation, because fact finding should proceed from examination of the whole factory.

ASME STD No.101, distinguishes between two types of process charts.

1. Operation process charts – Which constitute a general layout showing the principle operations and inspections, as well as the points at which the materials enters the process.

2. Flow process charts – Which represents a more detailed picture, describing the activities associated with materials, men or machines and which record the sequence of operations, transportations, inspections delays and storages that occur.

The Advantages of Process charting :-

1. It is convenient means of presenting overall information on a factory in limited space and is a record for future reference.

2. Detailed can be recorded on the chart in the factory when the job is observed, so that the chart relatives the mind of carrying.

3. It forces the analysis of work to be made in a quick and logical fashion according to (i) the sequence in which the work is done (ii) the materials or things which do the work (iii) the type of work done (iv) The relationship between several production flaws.

4. It is used to explain proposals for rationalising work and improving methods to the parties concerned.

3.3 PRODUCTION MASTER PROGRAM

The prepare the production master program the operation process chart demonstration the final sequence of operation is required, the following figure shows as typical example of such program for the manufacturing product constituting eight sub-parts.

After manufacturing the sub parts which will undergo various operation prior to final assembly. The program is based on the final delivery to be maintained and treated as zero base denoting the commencement of production by tails of the individual components on the charts by negative time units. Since master program, include the information about the type of machine required and time consumption of performance the operation in question. Such type of data is to be collected first alter studying the manufacturing drawings of completion of programming, the effect of sequencing on final schedule will be available.

Case Study – The following are the sequence of operation.

1. All parts are produced.

2. Parts are grouped in sub-assemblies.

I A + B + C II D + E III F + G

3. Sub-assembly 1 is subject to an operation before further sub assembly 4. 1 + II

5. ( I + II ) is subject to an operation.

6. In the mean time, III + II are required 7. (III + II) is subject to an operation.

8. Final assembly takes place.

Notations :-

A/1, A/2 etc operation required to produce part A M/52 - Machine on which operation A/1 is made.

A - assembly operation

Op - Refers to one of the operation
