The milling machines based parallel mechanisms with more than 3-dof. have high stiffnes and flexability in machining of the complicated workpieces. Accuracy and repeatability of these machines will be enhanced by applying calibration procedures. In this paper a 4-Dof milling machine based parallel mechanism was introduced. The required tests to find positioning errors have been done. After applying error compensation process on controller, the positioning errors of each of the rails were measured again. It was resulted the positioning errors of rails have been decreased and the accuracy of milling machine was enhanced.
