What is Gauge and Types of Gauges in MSA?
→ Gauges are the inspection tools without scale which are used to check manufacturing parts.→ Gauges do not indicate the actual value of the inspected dimension on the parts.
→ They can only be used to determine whether the inspected part has been made within the specified limit.
→ A clear distinction between measuring instruments and gauges is not always observed, at that times Gauges are used largely for measuring work.
1) Types of Gauges:
→ Various Gauges are mentioned below:
➤ (a) Standard Gauges:
∎ If the gauge is an exact copy of the mating part of the component to be checked, it is called Standard Gauge∎ Widely used for checking the limit of the dimensions of the part, i.e lower limit and higher limit they are known as "Go" and "No-Go" gauge
∎ Examples : Ring gauge, Plug gauge, Slip gauge etc....
➤ (b) Non-Standard Gauges:
∎ The gauge has no accurate standard measurement but it is made from some relative reference is called non-standard gauges.∎ Examples: Checking fixture, Temples etc....
2) Gauges are needed due to the following reasons:
→ Inter-changeability of parts.
→ Smooth Assembly.
→ Easiness in manufacturing
3) Handling of Gauges:
→ Do not use gauges as a hammer, this will cause deformation of the gauge.
→ Avoid any hard/sharp object to come in contact with the gauge, this will cause a dent/scratches on the gauge surface.
→ Do not force the gauge inside the hole to be measured, this will cause fast wear and damage the gauge, Let the gauge enter the hole with its own weight.
→ After usage, grease/oil should be applied and kept at a proper place.
