The paper discusses two methods to implement error compensation framework for NC machining. In the first case a novel real-time co-interpolator is utilized that has been developed and demonstrated on a machine tool equipped with an open architecture controller (OAC). The second solution features near-time reprocessing of the NC programs, that is more suitable for existing machining systems. A P-type, iterative learning control (ILC) algorithm is also presented for calculating the error compensation values. The paper concludes with the results of machining tests, showing the effectiveness of the error compensation methodologies.
