three principal groups of surface texture parameters have been standardized in connection with the complete symbol and are defined as R, W and P profiles; the R profile series relates to roughness parameters

Vastavalt standardile ISO 21920 - 2:2021 ja EVS-EN ISO 21920-2:2022 kasutatakse mõisteid profiili pinna tekstuur ja selle iseloomustamiseks pinnakareduse R-parameetreid.
Hea teada
According to new standard ISO 21920-2:2021 the profile surfase texture term is used and for indication of profile surface texture R-parameters terms are used.
There are many parameters used to characterize surface roughness, all of which are typically measured by passing a sharp, conical diamond stylus over the surface with controlled force and velocity.
If a surface is to be machined and a particular quality surface texture is desired then a standard machining symbol is added to the drawing with a number which gives the maximum permissible roughness expressed numerically in micrometres.
