Flexible right sized honing technology for fast engine finishing
TypeArticles dans des revues avec comité de lecture
The paper discusses a flexible honing technology by describing the new prototype machine with its specificity. Three original methods produced by the flexible honing prototype have been studied. A path combines the two contemporary methods of industrial honing: the helical slide honing at 135 ° at the bottom of the cylinder and the conventional honing at 45 ° on the upper part. This method of honing shows the effectiveness of specific motion tracking to remove traces of inversions. Circular trajectories with large radii can be traveled quickly without consuming too much energy. The high cutting speed promotes the removal of material thus saving time. Finally, the multi-circle paths can get original textures thus proving the feasibility of all patterns.

Simulation of Roughness and Surface Texture Evolution at Macroscopic Scale During Cylinder Honing Process GOELDEL, Benoit; EL MANSORI, Mohamed; DUMUR, Didier (Elsevier, 2013)The honing process produces surface liners with specific functional properties. Engine performances and life expectancy are directly impacted by the quality of honed surface. The form quality, the roughness and the surface ...
GOELDEL, Benoit; EL MANSORI, Mohamed; DUMUR, Didier (Elsevier, 2012)The form quality, the roughness and the surface appearance produced by honing minimizes the friction of the piston in the liner. The process is however mechanically complex and the selection of the process parameters is ...
