Abstract
The purpose of the present invention is to provide a damage-point estimation device that is capable of more accurately extracting points susceptible to damage in a linear-motion guide mechanism for a robot. A damage-point estimation devicecomprises: a data acquisition unitthat acquires physical parameters concerning the motion of a robotwith respect to individual axes and external forces acting on the robotat individual times when an action program for the robotis executed; an external-force and moment calculation unitthat calculates the external forces and moments acting on a reference position of a slide member at the individual times; a load calculation unitthat calculates the loads acting on a slider at the individual times; an equivalent load calculation unitthat calculates the equivalent loads of the slider at the individual times; an estimated-damage-value calculation unitthat calculates the estimated damage values of the slider at the individual times; and an estimated damage point extraction unitthat extracts an estimated damage point of the linear-motion guide mechanism.
