Form/Cylindricity cylinders
Cylindricity tolerances can be applied to cylinders. The tolerance
screen is used to specify the acceptable deviation from a perfect cyl-
inder.
Enter the acceptable form deviation into the Tol Zone data field.
Form/Flatness planes
Flatness tolerances can be applied to planes. The tolerance screen is
used to specify the acceptable deviation from a perfect plane.
Enter the acceptable form deviation into the Tol Zone data field.
Orientation/Perpendicularity lines, cylinders, cones, planes
Perpendicularity tolerances can be applied to lines, cylinders, cones
and planes. Perpendicularity tolerances are used to specify the accept-
able deviation from a line, axis or plane perfectly perpendicular to a
Reference feature.
Enter the acceptable perpendicularity deviation value into the Tol Zone
data field, and then enter the number of the reference feature for the
Perpendicularity tolerance into the Ref Feature data field.
Orientation/Parallelism lines, cylinders, cones
Parallelism tolerances can be applied to lines, cylinders and cones.
Parallelism tolerances are used to specify the acceptable deviation
from a line or axis perfectly parallel to a reference feature.
Enter the acceptable parallelism deviation into the Tol Zone data field,
and then enter the number of the reference feature for the parallelism
tolerance into the Ref Feature data field.
