Cutoff filter measures the wavelength at which the surface structure is distinguished between waviness data and roughness. Appropriate selection of the correct filter cutoff in software is important ...

Being able to quantify a surface finish is both a complex and necessary task. While surface topography relates to a three-dimensional property, the most accepted surface measurement parameter is ...

Adopted by the CSDA and recommended by ACI Committee 310, ST-115 is a quantifiable standard that designates floors by a surface texture grade. Since the moment polished concrete was born, it was ...

The performance, reliability and longevity of machined parts often depend on the physical characteristics of their functional surfaces. However, legacy surface roughness parameters, such as R a, are ...

Three new surface finishes for as-cast formed concrete are defined in the new ACI 301-10 Specifications for Structural Concrete, which supersedes ACI 301-05. Rough-Form and Smooth-Form As-Cast ...

All plastic molders understand that the surface texture of the mold cavity and core will transfer a texture to the corresponding molded part. But even experienced molders can be unclear about the ...
