A method of machining at least one dental restoration () from a workpiece () using one or more dental took (), including a step of defining, a target contour () of the dental restoration (); also including a step of predicting the deflection of the dental tool () during pre-machining through a model based on one or more machining parameters; a step of determining based on the prediction step one or more primary locations () at which the target contour () would have been damaged during pre-machining; a step of modifying the target contour () or the corresponding machining path by adding an oversize of material () substantially only at the primary locations () for preventing damage; and a step of pre-machining the workpiece () based on the modified target contour () or the corresponding modified machining path.
