katseliselt määratav tegur lõiketöödeldavuse hindamiseks kokkuleppelise etalonmaterjali (taval. termotöötlemata madalsüsinikteras) suhtes (vt lõiketöödeldavus)
Hea teada
Kerglõiketöödeldavatel materjalidel on lõiketöödeldavustegur suurem kui 1 (suurem kui 100%) , rasklõiketöödeldavatel alla 1 (vähem kui 100%).
a relative measure of the machineability of an engineering material under specified standard conditions (see: machineability)
Hea teada
Machineability rating attempts to quantify the machineability of various materials and is usually expressed as a percentage or normalized value in comparison with machineability of reference material. A material with a machineability rating less than 100% would be more difficult to machine than material with a value more than 100%.
