Modeling of interferences during thread milling operation
Article dans une revue avec comité de lecture
Thread milling is becoming more and more employed as a technique for producing thread, due to its advantages for industrial manufacturing sectors, such as the aeronautics, aerospace, and energy industries. The thread milling operation is atypical and several aspects have to be taken into account to perform it in good conditions. As for milling or grinding worms, grooves, thread or others sculptured surfaces, in thread milling, there exists a geometrical interference between the tool and the nominal surface which would be obtained. Thread mills have quite complex geometry and their profile has an effect on the machined thread. The present study details geometrical aspects of the thread milling process. This article deals with the link between thread mill geometry and nominal thread profile. An approach is proposed to analyze the thread profile generated by the thread mill envelope. It is deduced that thread milling produces interferences, i.e. the machined thread profile is affected by an overcut. A method is proposed to correct this geometrical error in order to produce accurate thread.

Article dans une revue avec comité de lectureFROMENTIN, Guillaume; POULACHON, Gérard (Springer Verlag, 2010)Thread milling is a method which is increasingly used for machining thread. For this operation, a helical interpolation is required. Furthermore, the thread mill is a tool whose geometry is rather complex. Its envelope ...
A generalised geometrical model of turning operations for cutting force modelling using edge discretisation Article dans une revue avec comité de lectureCAMPOCASSO, Sébastien; COSTES, Jean-Philippe; FROMENTIN, Guillaume; BISSEY BRETON, Stéphanie; POULACHON, Gérard (Elsevier, 2015)The knowledge of cutting forces is of prime importance to ensure the success of cutting operations, the desired properties of the machined parts and therefore the functionality of the workpieces. Edge discretisation is one ...
