Abstract
The milling process is widely used industrially and the quality of the obtained milled products should becontrolled because it affects their performance in exercise. This work correlates the quality of themachined surfaces with the adopted locating system, the shape deviations of the workpiece datum andthe machine tool. In other terms three error sources of machined surfaces were taken into account in theproposed method. An analytical model was set up and implemented through Matlab® to simulate thequality effects of a milling process. It was applied to two face milling processes characterized by twodifferent locator configurations. It was proved that machine tool volumetric error influences the flatnessof the milled surface, while the locator configuration and the datum form deviation affect the orientationof the milled surface, as should be actuallyI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
