rettificare

Rettificare is an Italian verb with several related meanings centered on making something correct, right, or precise. In general use, it denotes the act of correcting an error, adjusting a statement, document, or situation to bring it into accuracy, or reforming a practice to be proper.

In mechanical engineering and metrology, rettificare refers to a finishing process known as grinding. It involves removing small amounts of material with a grinding wheel to achieve precise dimensions and a high-quality surface finish. Variants include external rettifica (grinding of external surfaces), internal rettifica (internal grinding), and cylindrical or plane rettifica, each aimed at tight tolerances and smoothness required in components such as gears, shafts, and precision bearings.

In electrical engineering, rettificazione describes the conversion of alternating current (AC) to direct current (DC). The process, known as rettificazione, uses rectifiers (diodes or thyristors) to produce a unidirectional output. The verb rettificare can thus be used to indicate performing this conversion or to refer to rectifying a waveform or signal.

In administrative and legal contexts, rettificare denotes issuing a correction to a document or to a public statement. A rettifica may correct an error in a newspaper, a legal record, or financial entries, and the noun rettifica is commonly used for the correction itself or for the correction action.

Etymology: the term derives from Latin rectificare, meaning “to make straight,” from rectus “straight, right.”
