Abstract
A method determines the wear of axles of a robot arm of an industrial robot. A torque profile of at least one axle taken during at least one working cycle of the industrial robot is used as a basis for an analysis. The torque profile is analyzed for portions of the torque profile that exceed a previously fixed torque band, and current axial wear is determined by assessing the frequency and/or the curve profile of the portions of the torque profile. A system is provided for determining the wear.
