  • pikkus, milleks on profiiliosade kumulatiivne pikkus, mida lõikab joon samal tasandil c
    Good to know
    • Taseme c = 0 µm korral on tegemist tugikõrgusega, milleks on mõõteulatusega piiratud profiili maksimaalne kõrgus hindamispikkuse le piires.
  • length function what is it for the cumulated length of the profile portions intersected by a line at level c
    Good to know
    • The reference height for the level c = 0 µm is the maximum height of the scale-limited profile within the evaluation length le.
materjali pikkus
Usage examples
  • Pinna tekstuuri materjali pikkus, nt Rml(c), on pinnamaterjali akumuleeritud pikkus hindamispikkusel L konkreetsel lõiketasandil c ning see on Abbott-Firestone'i kõvera (koormuspikkuse suhe) põhiparameeter, mida kasutatakse selle hindamiseks, kui suur osa pinnast koormust kannab, üldiselt väljendatuna protsendi abil.

material length
Usage examples
  • Material length of surface texture, for example Rml(c), is the the accumulated length of surface material on the evaluation length L at a specific cut level c, and is a key parameter in the Abbott-Firestone curve (load length ratio) used to determine how much of a surface will support a load, generally expressed as a percentage.
