Resultant geometric variation of a fixtured workpiece Part I: a simulation

Blog Article

When a workpiece is fixtured for a machining or inspection operation, click here the accuracy of an operation is mainly determined by the efficiency of the fixturing method.Variability in manufactured workpiece is hardly inevitable.When such variability is found at contact areas between the workpiece and the fixture, errors in location are expected.

The errors will affect quality of features to be produced.This paper developed an algorithm to determine variant final locations of a displaced workpiece given normally distributed read more errorsat contact points.Resultant geometric variation of workpiece location reveals interesting information which is beneficial in tolerance planning.
