Summary: | It has long been accepted that established 2-Dimensional (2D) surface parameters are no longer sufficient to completely specify the surface finish of engineering components. Engineering surfaces can be recorded, and interact as, 3-Dimensional (3D) topographies. Therefore, descriptors (parameters) need to elucidate 3D surface texture. Empirical evidence is presented which demonstrates the effect of 3D topography upon component performance, which shows a good correlation between surface lay angle, friction and wear.
A novel technique is presented for modelling 3D surface topography and directionality which has been developed using vectors. The technique utilises 3D height range data obtained using a Form Talysurf instrument. The advantages of the technique are: detection and representation of surface levelling; improved visualisation; user-defined filtering; true representation of 3D surface properties, and the ability to detect changes in 3D surface properties which existing techniques are unable to recognise. Furthermore, using vector summation, a surface can be represented as a single vector stating the average gradient and directionality of the surface. This technique allows the analysis of 3D surface topography data in a new and novel way which will assist engineers in the assessment of engineering surfaces. |
