Q.I have a drawing of a plastic-moulded part with a minimum, as well as, a maximum, Ra tolerance for the surface finish. The surface in question, seal on an 'o' ring, to prevent fluid leakage. Is there any reason why I would not want less than the minimum Ra (0.2 in this case...
Surface Finish Cross Reference Charts Q. When machining or grinding parts, surface finish is a controlling dimension. When working with German prints, Rz is used to describe surface specifications. DIN standards. Can anyone recommend a cross reference sheet showing Rz vs. Ra vs. RMS ? Ra & RM...
Surface roughness average (Ra), also know as arithmetric average (AA) is rated as the arithmetic average deviation of the surface valleys and peaks expressed in micro inches or micro meters. ISO standards use the term CLA (Center Line Average). Both are interpreted identical. Where Ra is the...

(AM) components can have deleterious effects on the properties of the final part, such as corrosion resistance and fatigue life. Modification of the surface finish or parts produced by AM processes, such as cold spray, through methods such as mass finishing, can help to mitigate some of these...
Colour is here understood as a surface roughness modification that changes the appearance of the metal and gives it a matte finish. Chasing has two main steps, which are the preparation of the piece and the affixing of the decoration. Lines and slanting are intended to reaffirm the drawing ...
