Abstract:
1. A method for compensating for at least one of positional deviations and shape deviations in NC-controlled cutting production machines having an NC program, the method having the following steps: a) securing a workpiece; b) processing the workpiece using nominal data of the NC program, wherein the nominal data includes design values of the workpiece; c) acquiring set deviation data which is based on differences between the nominal data and measured values of the workpiece; d) optimizing the NC program using the acquired set deviation data; e) repeating steps a) to d) until at least one of required positional and shape tolerances have been achieved; f) returning of the set deviation data wherein a correction vector is allocated to each support point of a tool path; g) determining each correction vector by setting an actual geometry into clear comparison with a target geometry; and h) defining the clear comparison between associated regions by placing the correction vectors between areas having a change in curvature.
