摘要

A process for the sensorless compensation of the workpiece deformations in the case of program-controlled mechanical machining processes, whereinthe workpiece deformations in front of the machining process in the case of the program creation be compensated for by a first step in the geometric data and information data to be provided by means of boundary conditions, in a second process step, the data are corrected and in a third process step by means of the corrected data the program control is carried out, wherein the second step of iteratively in a plurality of recurrent calculation steps is carried out and the corrected data calculated in a step of calculating the input data for the subsequent calculation step form,characterized in that, in the first process step comprises the geometric data and boundary conditions of the track sections of a tool are calculated, wherein a division into a number k of the calculation steps, and that this path calculations and the number k of the necessary calculation steps to the second process step for correction with are transferred, wherein the calculation steps take place in successive time steps, and wherein the accuracy of the method, by the variation of the time step wide δt_n is adjustable.
