Rezumat:
Prezentul articol trateaza modul de interpretare al rugozitatii suprafetelor lemnoase, studiul fiind efectuat pe furnire obtinute din doua specii lemnoase: fag si stejar. Studiul comparativ s-a realizat prin masurarea rugozitatii pe doua echipamente ce utilizeaza: metoda cu palpator si metoda optica (fara contact) ce foloseste raza de lumina. Rezultatele masuratorilor efectuate pe cele doua echipamente au demonstrat ca metoda optica permite obtinerea unor rezultate mai precise, deoarece în valoarea masurata sunt cuprinse si elementele de structura anatomica ale lemnului.

Cuvinte cheie: rugozitate, suprafata din lemn, furnir, metoda cu palpator, metoda optica, raza de lumina.
