The paper is devoted to topic related with machining error correction for objects bounded by curvilinear surfaces manufactured on numerically controlled milling machine. Currently it is realized by two techniques. The first of them is called on-line and requires continuous correction of toolpath during the machining process. This approach requires expanded adaptive control systems. The second method called off-line is based on correction of machining control system outside the machine (on the basis of control measurement results). This paper shows methodology of machining shape error correction with off-line technique (with no constant and direct connection to CNC machine tool). This method is based on usage of CAD/CAM systems, numerically controlled milling machine and coordinate measuring machine. Manner of procedure proposed in this paper was verified on the example of ruled surface profile described with NURBS technique. Realization of this proposed methodology of machining error correction has shown significant accuracy correction of manufactured element.
