The automatic assessment of the texture of honed surfaces of cylinder bores based on microscopic grey level images is a demanding task. Although for some of the problems arising in this context, solutions are already given in literature [6,7,9], there remains a lot of work to be done due to the complexity of honing textures and the high quality demands made by combustion engine manufacturers. T...

The present paper describes the geometries of honing wheels used in final tooth-flank-finishing process automotive transmission gears. For micro honed gears to keep their required gear accuracy, improper a gear-honing wheel cause dressing interval be short. That is because stock removals are not uniform over tooth flank, then wear also uniform. As result, out tolerances. amount removal could de...

The quality of the honing texture on cylinder bores of combustion engines plays an important role with respect to oil consumption, noxious emissions, and running performance. To evaluate honed surfaces objectively, features describing the surface texture are extracted from 2-D data of the surface. The paper focuses on two crucial stages of the data analysis: the preprocessing, which aims at sup...
