A method of manufacturing a feature in a part with a cutting tool, includes machining a semi-finished shape of the feature, determining an actual position of at least one target point on a surface of the semi-finished shape, and computing a difference between the determined position of the at least one target point and a nominal position of the at least one target point on a digitized model of the part having the semi-finished shape of the feature. As a function of the difference, a correction to a position of the cutting tool on a nominal tool path to achieve the final shape of the feature from the semi-finished shape is determined, and the correction is used to define a corrected tool path. The finished shape of the feature is then machined with the cutting tool by moving the cutting tool along the corrected tool path.

A method for monitoring machining processes in workpiece processing including steps of planning a processing process on the basis of a predetermined final shape of a workpiece to be achieved in the processing process and of quality features of the final shape of the workpiece and simulating the planned processing process in a computer-aided simulation. Target values of parameters of the simulated processing process occurring during the simulated processing process are detected and stored in the context of the computer-aided simulation. During the real processing process carried out according to the planned and simulated processing process, the parameters considered in the simulation are monitored and the actual values thereof are detected. By comparing actual values of parameters detected during the real processing process with the target values of these parameters detected during the simulation, the quality of the processing process and/or of the processed workpiece is assessed.

A CNC machining device (1) comprises a control console (3) and a CNC machine (5).
