  • parameeter, milleks on südamiku/tuumiku pinna kõrgeima ja madalaima taseme vaheline kaugus
  • parameter what is it for the distance between the highest and lowest level of the core surface
  • parameter that is the distance between the highest and lowest levels of the core profile

Usage examples
  • Põhikõrgus viitab pinna metroloogias tavaliselt Sk parameetrile 3D-s või Pk ja Rk parameetrile 2D-s, mis esindab "südamiku/tuumiku" pinnakareduse sügavust – pinna tippude ja orgude kõrgust pärast vähendatud tippude ja orgude eemaldamist, ja see arvutatakse pindalalise materjalisuhte kõvera põhjal, mõõtes pinna funktsionaalset, koormust kandvat osa, mitte selle äärmuslikke kõrgeimaid punkte või sügavaid orge.

core height
Usage examples
  • Core height typically refers to the Sk parameter in 3D or Pk and Rk parameter in 2D in surface metrology, representing the "core" roughness depth — the peak-to-valley height of a surface after removing reduced peaks and valleys. It is calculated from the areal material ratio curve, measuring the functional, load-bearing portion of a surface rather than its extreme high points or deep valleys.
