Integration of the machining point of view in the product modelling: the fixturing features

摘要

A fixturing feature model of a part is presented in this paper. United with the machining feature model and the corresponding positioning, it allows a process plan to be generated effectively.Geometrical parameters typical of a good locating or a good clamping and indicators typical of the part behaviour during machining are defined. The capacity for a fixturing feature to be an efficient clamping and an accurate locating is considered.
