Definition: Machining precision refert to the degree to which the actual dimensions, shape and position of the machined part surface conform to the ideal geometric parameters required by the drawing. For size, the ideal geometric parameter is the average size; For surface geometry, it includes absolutes circles, cylinders, planes, cones and lines. Posiciones enim inter superficies sunt paralelae absolute, perpendiculare, coaxiale, symmetrice atque cetera. The deviation between actual and ideal geometric parameters is called machining error.

Machining accuracy and machining error are terms used to evaluate the geometric parameters of machined surfaces. Precisio machinae lathe CNC a nivelo tolerantiae mensura est. Minus nivellum, maius precisa. Errorem machinae a valoribus numericas reprezentata est. Quanto maior est valor, maior error. Exalta processura precisa resultat in parva processura errores, et vice versa.

Parametri facti per omni metodo processionis accipiti non sunt absolute accurate.

Qualitate machinarum ambulantis CNC dependit de qualitate machinarum parterum et qualitate congregationis instrumenti machinarum. Qualitate machinae parterum accuracionem machinae et qualitatem superficie includet.

Processing accuracy refers to the degree to which the actual geometric parameters (size, shape, and position) after processing are consistent with the ideal geometric parameters. Differentia inter eos errore machinae vocatur. Error machinae accuracionem machinae reflexit. Quanto maior error, inferior accuracio machinae; minor error, maior accuracio machinae.
