Feature of Lumbered bars


1. Orientation of the minus X reference surface The orientation of the minus X reference surface
from the y’ axis shall have the maximum
angular deviation of 15’


The orientation of the minus X refrence from the Z’ axis shall have the maximum angular deviation of 15’



2. Orientation of the Z reference surface The orientation of the Z reference surface from the X axis shall have the maximum angular deviation of 30’.



3. Centricity of the seed.
The seed be contained within the 3 mm
imaginally shaded area centered between the two Z surfaces.



4. Surface finish and flatness.
The minus X surface shall have a roughness of 12.5
m

m (Rz) and a flathness and parallelism of 0.05 mm
