Lingua quinque axis parterum optima machina est quae quinque instrumenta machinae ad processionem utilizat. Praecepta accuracionis valde importantia sunt in quinque partibus machinationis axis. Sequentes sunt aliquid opus accuracii commune: Positioning accuracii: Positioning accuracity of a five axis machine tool should meet the requirements of national or industry standards. Normally, its positioning accuracy should reach IT6 level or higher. Precisio repetitivae positionis: Precisio repetitionis positionis instrumenti quinque axis machinae est etiam indicator gravis pro mensurare precision sua. Precisio positionis repetitionis normale non excedet 1,0 μm. Machining accuractia: The machining accuracy of five axis machines is usually verified by machining test specimens. Precisio dimensionalis et precisa forma specimenorum processorum conformetur ad opus drawingorum. Stabilitate: quinque instrumenta machinae ad axis stabilia manere debet in processione longo tempore ut non efficiat accuracionem machinae a causa factoribus, quales temperatura et vibratione. Tool wear: Tools used in five axis machining should be regularly inspected and replaced to ensure the roughness and dimensional accuracy of the machined surface. At the same time, operators need to undergo professional training and skills enhancement, master the correct processing methods and techniques, and avoid processing errors caused by incorrecta operation.
