Answer :
Final answer:
The dial indicator movement can be caused by machine vibrations, operator errors, and material properties.
Explanation:
The dial indicator movement, also known as runout error, can be a result of several factors:
- Machine vibrations: Vibrations in the machine can cause the dial indicator to move and give inaccurate readings. This can be minimized by ensuring proper machine maintenance and damping measures.
- Operator errors: Incorrect usage or mishandling of the dial indicator can lead to movement and errors in measurements. It is important for operators to be trained and follow proper procedures.
- Material properties: The properties of the material being measured, such as its elasticity or surface condition, can affect the movement of the dial indicator. For example, a flexible or rough surface may cause the indicator to move more.
The dial indicator movement or runout error can be a result of several factors including a) material properties, b) temperature variations, c) machine vibrations, and d) operator errors. These can all affect the precision of a measurement.
For instance, material properties such as hardness or elasticity can cause changes in how the dial indicator reads. Depending on the temperature variations, materials can expand or contract, affecting the measurements. Machine vibrations are another common source of runout error, as they can interfere with the accuracy of the dial indicator. Lastly, operator errors like incorrect usage or misreading can lead to mistakes in measurement.
