Handling of Alternative Processes for Machining of Aeronautical Parts in a CAPP System

International audienceThis paper focuses on the management of alternatives machining operations,essentially from an access orientation point of view, during computer aided processplanning of aeronautical parts. Characteristics of these parts entail to consider a largeramount of alternative machining operations for one single feature than considered inusual approaches. Using visibility map concept, taxonomy of “machining direction sets”is proposed to manage these alternatives. Then, procedure to handle theses alternativessets through a step of the set-up planning stage is suggested
