A new technology has been worked out, that permits to carry out one of shipboard diesel engines main and most important devices – crankshaft – repair without removing it from engine. Respectively, it is not necessary to dismount the whole engine and this innovative technology remarkably reducing the costs of repairs. However, impact of this novel grinding technology to the surface roughness parameters is not jet clear and requires addition scientific analysis. Machining technology and cutting regimes, as well as material of instrument have direct influence to the roughness of surface and consequently to the quality of whole repair. Therefore, to realise this innovation, it is necessary to carry out the additional research of grinding technological regimes impact to the crankshaft main and crankpin bearings (journals) surface formation. The present roughness researches are based on surface two dimensional roughness parameters – simple profile analysis. Nevertheless, in practice any surface has three dimensions, roughness as well. Thusly it is necessary to create new theoretical 3-D surface model also for crankshaft bearings surfaces. This will allows analysing the full-scale impact of grinding technological regimes influence to the real three-dimensional surface. The optimal 3-D surface roughness parameters for crankshafts are following: mean arithmetical deviation of surface RaT, and two perpendicular surface spacing parameters between the peaks Sm1 and Sm2. Multifactorial research shows individual significance of each technological regime and overall impact to the 3-D parameter RaT, Sm1 and Sm2. Thusly it is possible to locate the most optimal and appropriate grinding technological parameters.
