METHOD AND CONTROL DEVICE FOR DETERMINATION OF THE TIME DURATION BEFORE A MACHINE ELEMENT REQUIRES SERVICING

摘要

The invention relates to a method for determination of the time duration (T) before a machine element (6) of a machine requires servicing, comprising the following method steps: determination of a position-related load curve (BK) of the machine element (6) on the basis of a process variable (a, r) and of a position variable (x) for a manufacturing process to be evaluated, storage of the load curve (BK) for each manufacturing process to be evaluated, determination of a summation curve (SK) by addition of the stored load curves (BK) and determination of the time duration (T) before the machine element (6) requires servicing, on the basis of a separation (A) between a predetermined limit variable (GK) and the summation curve (SK). The invention also relates to a control device (12) relating to this for the machine. The invention makes it possible to determine the time duration (T) before a machine element (6) of a machine requires servicing.
