All technological processes leading to the final surface visage of mechanical components create on its surface characteristic pattern. These surface patterns subsequently play a significant role in terms of their function and lubrication, particularly in the case of surface contact pairs. However, inclusion of the actual surface patterns of machine parts as one of the input parameters of the computational simulation of friction losses is still not common. This article describes a complex computational model for solving the frictional losses for directionally oriented and non-oriented sliding surfaces. The first part of this article provides information regarding the description of surface roughness. Attention is paid to the two basic possibilities of obtaining the surface characteristics – namely those obtained by measurement (3D scanning surface) or those obtained using a specialized software generator. The software generator of surface characteristics is based on the relation: z ( x, y ) =
