Every angle may be defined in different
ways. The most popular way is a definition
in Degrees / Minutes / Seconds.
This is shown in the graph.
Such a definition is especially useful for
larger angles.
With an angular measuring instrument not
only an angle may be measured but also
the height of a certain point over a defined
base length can be calculated. for a profile
of a line or a surface) Due to this simple
and reliable method a number of tasks are
possible, especially for measuring guide
ways and surface plates definition.
Angle
α
= Height of the measuring point related to a defined
base.
Height of the measuring point = tan
α
x length of base
Example:
Angle =
Height related to a defined base.
e.g. 22 µm/m
Example:
Because the relation µm/m is 1/1'000'000 the same
relation can also be applied to micro inch/inch
Angle = Height related to a defined base.
e.g.
22 µm/m are equal to 22 micro inch/inch or
0,00002 Inch / Inch
