simplest meaning of manufacturing process

MANUFACTURING PROCESS

   Manufacturing is involved in turning raw material to finished products to be used for some   purpose

•        In the present age there have been increasing demands on the product performance by way of desirable  properties such as

•        Resistance to high temperatures

•        Higher Operating speeds

•        Extra Loads

•        Newer Materials

•        Working Conditions

Importance of Manufacturing:

•        The benefits of civilisation which we enjoy today are essentially due to the improved quality of products available to us

•        The improvement in the quality of goods can be achieved with proper design that takes into consideration the functional requirement as well as its manufacturing aspects

•        The design process that would take proper care of the manufacturing process as well would be the ideal one

•        This would ensure a better product being made available at an economical cost.

Classification of Manufacturing Process

All manufacturing processes can be grouped into two major categories:

1.Primary manufacturing processes: Involved in the initial breakdown of the original material to shapes that can be processed into final products. Ex: Casting, Rolling, Extrusion,Investment casting etc.

INVESTMENT CASTING

2.Secondary manufacturing processes: These processes take the products of some primary process and change the geometry and properties to the semi-finished or finished stage

               Ex: Metal removing processes.

METAL REMOVAL BY MILLING

Selection of manufacturing process Depends on :

•        Type and nature of the starting material

•        Volume of production

•        Expected quality and properties of the material

•        Technical viability of the process

•        Economy

•        Geometrical shape, jigs, fixtures, gauges, equipment available

•        Delivery dates
