Correct option is D
GO and NO GO gauge are used to check the internal diameter of workpiece and hole size.
A GO gauge will check upper limit of shaft and lower limit of hole. A
GO gauge is a type of limit gauge used in quality control to verify whether a workpiece dimension falls within the specified tolerance range. The "GO" side of the gauge is designed to fit into or over the workpiece when the dimensions are at or below the upper limit of the tolerance. In the context of holes, a GO gauge ensures that the hole is not undersized.
Limit Gauges: Used to check whether manufactured parts meet specified dimensions without requiring precise measurement.
GO and NO-GO Gauges:
The GO gauge should fit easily if the size is within the lower tolerance limit.
The NO-GO gauge must not fit if the part size exceeds the upper tolerance limit.
Applications: Commonly used in mass production to ensure dimensional accuracy.
Types of Gauges: Plug gauges for holes, ring gauges for shafts, and thread gauges for screw threads.
Advantages: Simple, quick, and does not require skilled labor to use.
Material: Often made of hardened steel for durability and wear resistance.
