Types and Functions of Jigs and Fixtures
JIGS AND FIXTURES
Jigs and fixtures are production-workholding devices
used to manufacture duplicate parts accurately. The
correct relationship and alignment between the cutter,
or other tool, and the workpiece must be maintained.
To do this, a jig or fixture is designed and built to hold,
support, and locate every part to ensure that each is
drilled or machined within the specified limits.
Jigs and fixtures are so closely related that the
terms are sometimes confuse ....etc

advantage and disadvantage of object counter using 8051 microcontroller

Object counter using 8051 microcontroller.
This article is about a simple object counter/visitor counter using 8051 microcontroller . AT89S51 belonging to the 8051 family is the microcontroller used here. This circuit can count the number of objects passing across a line , number of persons passing through a gate/door and so on. The can be simply divided into two sections i.e. the sensor section and the display section.

Sensor.

The sensor part consists of a ultra bright ....etc

Elements of Jigs and Fixtures



1: Body:
The jig body is generally made of cost iron by casting process or fabricated by welding together various slabs and bars of mild steel. It may be heat treated to relief the stresses. Body is the most prominent feature of the jig. Its main purpose is to support and house the job.

The various jig body are follows:

(A):Plane Type Jig:
Plane type jig is the simplest type, it is used when plane holes are to be drilled. It has either d ....etc

Black cotton soils and oher expansive soils have typical characteristics of shrinkage and swelling due to moisture movement through them. During rainy season, moisture penetrates into these soils, due to which they swell. Most of the fine grained clays, including black cotton soils have their grains which are more or less in the form of platelets or sheets (just like leafs of a book), and their grains are not round. When moisture enter betwecn the platelets under some hydrostatic pressure, the particles separare out, resulting in increase in th ....etc
