Mathematical Modeling of Wear of Plane Translation Couples

Abstract The use of guide ways in apparatus, devices and machines construction is frequent that the aspects concerning their accuracy and durability are elements defining technical performances. The paper proposes a mathematical model for calculating the wear of torques with sliding motion. The proposed model makes it possible to establish a link between wear and tear and the accuracy of the movement of the moving part during operation. The model can be applied in the design phase for a known geometry and operating conditions.
