geomeetriaelement, mis füüsiliselt töödeldava osise tegelikul pinnal ei eksisteeri ja mis ei ole loomult terviklik element
geometrical feature, which does not exist physically on the real surface of the workpiece and which is not natively a nominal integral feature
geometrical feature, which is a median, displaced, congruent or rerlected feature resulting from a set of operations on an integral or filtered feature
Silindri keskjoon on tuletatud element, mis on saadud silindri pinnast, mis on terviklik element. Nimisilindri telg on tuletatud nimielement. Kahe rööpse tasandi keskpind on tuletatud element, mis on saadud kahe rööpse tasandi pinnalt, mis moodustavad tervikliku elemendi. Kahe vastastikkuse nimirööppinna keskpind on tuletatud nimielement.
Good to know
Tuletatud element on saadud nimielemendist, juurdekuuluvast elemendist või eraldatud elemendist, ja on kvalifitseeritud vastavalt kui tuletatud nimielement, juurdekuuluv tuletatud element, või eraldatud element. Keskpunkt, keskjoon ja keskpind, mis on määratletud ühest või mitmest terviklikust elemendist, on tuletatud elemendi tüüpi.
The median line of a cylinder is a derived feature obtained from the cylindrical surface, which is an integral feature. The axis of the nominal cylinder is a nominal derived feature. The median surface of two opposite parallel planes is a derived feature obtained from the two opposite parallel planes, which constitute an integral feature. The median plane of the nominal two opposite parallel planes is a nominal derived feature.
Good to know
A derived feature can be established from a nominal integral surface, an associated integral surface, or an extracted integral surface. It is qualified respectively as a nominal derived feature, an associated. The centre point, the median line and the median surface defined from one or more integral features are types of derived features.
