Grind textures

Characterize the texture of grinding using the high resolution measurements of 4D InSpec. The instrument is able to distinguish height variations to 0.0002″ (5 micrometers), and lateral features as small as 0.00026″ (6.6 micrometers), from a measurement that takes about 1 second to make and process.

The resulting 3D measurement automatically reports the roughness of the texture, over a large field of view.

With the analysis tools, you can even draw a profile anywhere in the measurement and get a 2D roughness calculation.


In the screen captured measurement above, the Peak to Valley reported in the data is 3.34 thou (85 micrometers), and the RMS is 0.15748 thousands of an inch (4.0 micrometers).

In this measurement of a burr, (camera view on the left, 3d contour plot on the right) a cursor line has been drawn on the measurement, and the resulting profile for that segment appears in real time beneath it. PV and RMS can be provided for the 2D line profile as a simple selection in the interactive menus.
