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 ...

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 ...

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 ...

Almost a century ago the concept of measuring surface roughness started as a way to stop disputes and uncertainty between buyers and manufacturers. Today, it is a common identifier that is utilized ...

Stereo digital image correlation technique (stereo-DIC or 3D-DIC) has been widely used in three-dimensional (3D) shape and deformation measurement due to its high accuracy and flexibility. But it is a ...

The SJ-220 portable surface roughness measuring instrument has touchscreen and wireless capabilities. The intuitive touchscreen has a user interface that supports fingertip operations, including flick ...
