Measuring Machines (Ch #12)
•
Theoretical design requirements
•
Traditionally surface plates are most
commonly used for inspection from datum
surfaces.
–
Adaptability and accuracy
–
Potential errors for complex parts
•
The measuring machines have been
designed to combat these measuring
problems.
Measuring Machines
•
Recent Trends:
–
Combining mechanical instruments with
electronic sensing.
–
Advances in optical displacement
–
Numerical display of distances that originate
from each incremental part of the translational
movement by the instrument.
–
The development of highly stable structural
materials.
