\nMasina-unealta este un echipament cu care se genereaza suprafata pieselor prin procesul de aschiere, in anumite conditii de productivitate, precizie dimensionala si calitate a suprafetei.
\nCiclul de prelucrare consta in totalitatea miscarilor de actionare, necesare prelucrarii efective a unei piese pe o masina-unealta excluzand miscarile auxiliare.
\nCiclul de lucru – totalitatea miscarilor de actionare, necesare prelucrarii efective a unei piese pe o masina-unealta, incluzand si miscarile auxiliare.
\nOdata cu cresterea cerintelor de precizie in timpul prelucrarii corelata cu cresterea productivitatii muncii la prelucrarea prin aschiere, aria masinilor-unelte a evoluat, fiind o evolutie atat din punct de vedere a constructorului, cat si al utilizatorului. Aceasta evolutie se datoreaza dezvoltarii componentelor electronice, cat si al aplicarii informaticii industriale.<\/p>\n","protected":false},"excerpt":{"rendered":"Nu sunt date conform carora putem stabili un an al aparitiei acestora, mai ales tinand cont de definitia masinii-unelte, dar se cunosc masini de lucru apropiate notiunii de astazi (cu lant cinematic principal si lant cinematic de avans) abia la mijlocul secolului al XVI-lea.
