Effect of thread milling penetration strategies on the dimensional accuracy
TypeArticles dans des revues avec comité de lecture
Day by day the application of thread milling process is enhancing in industry because of its inherent advantages over other thread cutting techniques. The current study dwells on the interference issue, which is generated during thread milling. It was observed that there are two sources of interference on the thread produced i.e interference induced during mill penetration and during full machining. This interference leads to an overcut on the thread, thus it produces dimensionally inaccurate thread. The interference produced by penetration is much more as compared to interference generated during full machining of thread. Thus, there is a pressing need to analyze interference during penetration. So this study evaluates different applied penetration strategies and the level of interference produced. Further, the study suggests modified penetration strategies in order to reduce the interference produced and hence create more accurate thread. This investigation is supported by analytical modeling and experimental exploration.

Investigation of tool geometry effect and penetration strategies on cutting forces during thread milling SHARMA, Vishal; FROMENTIN, Guillaume; POULACHON, Gérard; BRENDLEN, Romain (SPRINGER, 2014)The application of thread milling is increasing in industry because of its inherent advantages over other thread cutting techniques. The objective of this study is to investigate the effect of milling cutter tool geometry ...
FROMENTIN, 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 ...
FROMENTIN, Guillaume; POULACHON, Gérard (Springer, 2010)Thread milling offers interesting possibilities for machining internal or external threads. This machining technique uses a mill with a triangular profile for metric threads and a helical interpolation strategy. Thus, the ...
A generalised geometrical model of turning operations for cutting force modelling using edge discretisation CAMPOCASSO, 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 ...
BAIZEAU, Thomas; CAMPOCASSO, Sébastien; FROMENTIN, Guillaume; ROSSI, Frédéric; POULACHON, Gérard (Elsevier, 2015)In the case of hard machining of steels, negative rake tools generate compressive deformation and high temperature under the cutting edge, leading to phase transformation or ”white layers”. The resulting surface integrity ...
