Abstract. Friction machines under consideration has a distinctive feature of implementation of forced movement of studied samples relative to each other due to force action transfer by friction. Analysis of evolution of structural components of the machines allowed to increase the accuracy characteristics of designed and developed friction machines by virtue of application of high-technology drives, precision guides, displacement sensors, as well as optimization of tribopair position. An original approach to comparing the errors of the machines of two design variants is proposed. The approach is based on the use of cyclic input-output diagrams for estimating the areas formed by the machines. Results of comparative analysis of qualitative characteristics and relative errors of the devices are presented.

Keywords: Tribal, reciprocal action, construction, signal processing algorithm, accuracy assessment
