INTRODUCTION TO MANUFACTURING PROCESSES

DEFINITIONS:

  • PRODUCE:

To bring forth or to yield. For example, farms produce fresh vegetables. To manufacture or produce or create economic goods. Natural products are also called produce, e.g., fresh eggs are produce of poultry farm.

  • PRODUCTION:

Manufacturing or mining or growing something (usually in large quantities) for sale; "he introduced more efficient methods of production" 2: a presentation for the stage or screen or radio or television; "have you seen the new production of Hamlet?" 3: the act or process of producing something; "Shakespeare's production of poetry was enormous"; "the production of white blood cells" 4: an artifact that has been created by someone or some process; "they improve their product every year"; "they export most of their agricultural production" [syn: product] 5: (law) the act of exhibiting in a court of law; "the appellate court demanded the production of all documents" 6: the quantity of something (as a commodity) that is created (usually within a given period of time); "production was up in the second quarter" [syn: output, yield] 7: a display that is exaggerated or unduly complicated; "she tends to make a big production out of nothing" 8: the creation of value or wealth by producing goods and services.

l            MANUFACTURE:

1.      To make or process (a raw material) into a finished product, especially by means of a large-scale industrial operation.

a.       To make or process (a product), especially with the use of industrial machines.

2.      To create, produce, or turn out in a mechanical manner: “His books seem to have been manufactured rather than composed” (Dwight Macdonald).

3.      To concoct or invent; fabricate: manufacture an excuse.

4.      To make or process goods, especially in large quantities and by means of industrial machines.

MANUFACTURING SYSTEM : It involves activities right from inception of a product. Before a company decides to manufacture a product it needs to do feasibility study, that involves market survey to assess acceptability. Working out of manufacturing costs, overhead costs, suitability of location of production unit, availability of raw material, transportation of raw and finished goods, etc. is done.

Once a report is accepted, then designing of product and its manufacturing processes are finalized. Quality standards and checking procedures are defined. Plant layouts are prepared and plant is constructed according to these layouts.

This entire system, spanning from feasibility study till the finished goods are packed and delivered, is known as manufacturing system. To sum up, manufacturing system involves:


lDefinition of a need

lConceptual design

lReview of initial design

lDesign Prototype

lProduction plan

lResource specifications

lManufacturing Prototype

lManufacturing

lInspection--quality checks

lPackaging - shipping

lCustomer response


 

MANUFACURING PROCESSES : The process to convert raw material into desired object by mechanical, chemical and other industrial means is called manufacturing process. The process may involve a single operation or series of operations. It is a part of manufacturing system.
