Introduction
A ring gage is a precision measuring tool used in mechanical engineering to measure the outside diameter of a cylindrical object. It is designed to check if the object being measured falls within the specified tolerance range.
Explanation
A ring gage consists of a cylindrical ring with an accurately machined inside diameter. The ring is typically made from hardened tool steel or tungsten carbide to ensure durability and accuracy. The inside diameter of the ring is designed to match the specified outside diameter of the object being measured.
When the object is inserted into the ring gage, it should fit snugly without any play or excessive resistance. If the object is too large or too small to fit into the ring gage, it indicates that the outside diameter is out of tolerance.
Measurement of Outside Diameter
The primary purpose of a ring gage is to measure the outside diameter of a cylindrical object. By comparing the size of the object to the inside diameter of the ring gage, engineers can determine whether the object meets the required specifications.
If the object is within the specified tolerance range, it means that the outside diameter is within the acceptable limits. However, if the object is larger or smaller than the inside diameter of the ring gage, it indicates that the outside diameter is out of tolerance.
Limitations of Ring Gage
While a ring gage is an effective tool for measuring the outside diameter of a cylindrical object, it is important to note that it does not provide information about the roundness of the object.
Roundness refers to the deviation of the object's shape from a perfect circle. It is a measure of how closely the object's contour matches the ideal circular shape. A ring gage cannot determine the roundness of an object because it only measures the outside diameter.
To measure the roundness of an object, specialized equipment such as a roundness tester or a coordinate measuring machine (CMM) is required. These tools use different methods, such as contact or non-contact measurements, to assess the roundness of a cylindrical object.
Conclusion
In conclusion, a ring gage is primarily used for measuring the outside diameter of a cylindrical object. It is a useful tool in mechanical engineering for quality control and ensuring that the objects being produced meet the required specifications. However, it is important to note that a ring gage does not measure roundness and is limited to measuring the outside diameter only.
