Along with the flying development of computer technique , price relations of performance enhance constantly , numerical system basing on computer has become the mainstream of control - system development 隨著計(jì)算機(jī)技術(shù)的飛速發(fā)展,性價(jià)比不斷提高,基于計(jì)算機(jī)的數(shù)控系統(tǒng)已成為控制系統(tǒng)發(fā)展的主流。
The computerized numerical control ( cnc ) is the basis of advanced manufacture technology . in past , most numerical systems were used specially . when they were finalized the design , it was not easy to update 計(jì)算機(jī)數(shù)控( cnc )是先進(jìn)制造技術(shù)的基礎(chǔ),以往數(shù)控系統(tǒng)多是專用的,定型后不易升級(jí);如今的pc機(jī)功能強(qiáng)大,具有開放性特點(diǎn)。
