3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Surface processing level degreeofsurfacefinish
After a certain level of surface quality of the surface obtained by processing, the code represents.
3.2
The surface roughness surfaceroughness
Machined surface having a smaller pitch and the tiny valley irregularities. The distance between the peaks or two troughs (pitch) is small (in 1mm
Or less) are micro geometry error.
3.3
Arithmetical mean deviation arithmeticalmeandeviationoftheprofile
Ra
The roughness profile within the sampling length offset from the arithmetic average of the absolute value, in microns (μm).
4 principle of the method
The process of hot-rolled stainless steel plate surface processing level is generally identified by visual inspection; cold-rolled stainless steel plate surface processing level mainly through
Through preliminary visual identification, if necessary, with the detection of surface roughness and mechanical properties were identified.
5 Instruments
Surface Roughness Tester
With a stylus instrument to directly measure the contour or have the same functions for data acquisition and processing contour curves.
