Target Class This selection defines the target class for the alignment resolution.
The level of the machine alignment can be described according to the criteria
specified in the following table and shown graphically in the following figure
where:
a is the axial strain
b
max.mc
is the maximum bending strain
β
mc
is the percent bending
