INSPECTION AND QUALITY CONTROL

INSPECTION AND QUALITY CONTROL

A product is manufactured to perform desired
functions. It must have a specified dimension such as length, width, height,
diameter and surface smoothness to perform or accomplish
its intended function. It means that each
product requires a defined size, shape and other characteristics
as per the design specifications. For manufacturing the product to the specified size, the dimensions should be
measured and checked during and after the manufacturing process. It involves
measuring the size, smoothness and other features, in addition to their
checking.
These activities are called measurement and inspection respectively.

In the era of globalization, every industry must pay sufficient attention towards maintaining
quality because it is another important requirement or function of a
production unit. If a manufacturing concern wants
to survive for longer time and to maintain its reputation among the users, it should under all
condition apply enough efforts not only to keep up the standard of quality of
its products once established but to improve upon the same from time to time.
For this, every manufacturing concern must maintain a full-fledged inspection
and quality control department which inspects
the product at different stages of its production. Vigilant inspection of raw materials and products depends upon
the entire process of standardization. The production unit of manufacturing
concern must produce identical products. However a minor variation may be
allowed to a predetermined amount in their finished dimensions of the products. The two extremities of
dimensions of the product are called limits.
All the parts of which the finished dimensions lie within these limits
are acceptable parts. This facilitates easy and quicker production, easy
inspection, requires less skill on the part of worker and accommodates a slight inaccuracy in the machine as well,
resulting in an over all reductionย  in the production cost of the part.
