Nowadays, precision methods for computerized numerical control (CNC) machine tools analyze geometric, kinematic, dynamic, and thermal errors separately. This article aims at numerical compensation of elastic deformations in CNC machine tools. A digital twin of CNC machine tools provides physical relationships based on SI units, precision error predictions, and digital methods for numerical compensation of elastic deformations. The evaluation of elastic error compensation modules is given for geometric, kinematic, dynamic, and thermal errors. The summary focuses on the most important results and provides an outlook on future applications.
