Distortion produces curved images from straight lines in the object. The type and degree of distortion visible is intimately related to the possible spherical aberration in the magnifier and is usually most severe in high-powered lenses.

Barreldistortion

The circle added to the basic symbol indicates, the surface must be produced by processes such as casting, forging, hot finishing, cold finishing, die casting, powder metallurgy or injection moulding without subsequent removal of material.

The horizontal bar added to the basic symbol indicates that, material removal by machining is required and extra material must be provided for that purpose.

Many manufacturing processes how a speed-surface smoothness trade-off. Smooth surfaces require the machine to “go slower”.

ABERRATION definition: a temporary change from what usually happens. Learn more.

Distortion is present when straight lines running parallel with the picture edges appear to bow outward (barrel distortion) or inward (pincushion distortion).

Surface Roughnesses can be complicated, and the similarity of the symbols across various standards contributes to this complexity. N-Grade converts the specified roughness to a value between "01" and "12". This simplification eliminates the need to consider the various standards, such as the distinctions between average profile height and maximum profile height, etc. These values are calculated by WERK24 whenever possible. Werk24 converts surface roughness parameters to N-Grades according to the following table.

Curvature of field and distortion refer to the location of image points with respect to one another. Even though the former three aberrations may be corrected for in the design of a lens, these two aberrations could remain. In curvature of field, the image of a plane object perpendicular…

Surface finish is the specified smoothness required on the finished surface of that part. This surface finish can be obtained by machining, grinding, honing, or lapping, etc. Surface finish is generally required for mechanical components where these components must fit together perfectly, move against each other, or form a sealing interface.
