Limit Gauges
LIMITGAUGES
·
A limit gauge is not a measuring gauge.
Just they are used as inspecting gauges.
·
The limit gauges are used in inspection
by methods of attributes.
·
This gives the information about the
products which may be either within the prescribed limit or not.
·
By using limit gauges report, the
control charts of P and C charts are drawn to control invariance of the
products.
·
This procedure is mostly performed by
the quality control department of each and every industry.
·
Limit gauges are mainly used for checking
for cylindrical holes of identical components with a large numbers in mass
production.
Purpose
of using limit gauges
·
Components are manufactured as per the
specified tolerance limits, upper limit and lower limit. The dimension of each
component should be within this upper and lower limit.
·
If the dimensions are outside these
limits, the components will be rejected.
·
If we use any measuring instruments to
check these dimensions, the processes will

·
It is just enough whether the size of
the component is within the prescribed limits or not. For this purpose, we can
make use of gauges known as limit gauges.
The
common types are as follows:
