A method and an apparatus for cutting machining of workpieces with rotationally symmetrical, in particular eccentrically rotationally symmetrical surfaces, in particular the big-end bearing locations of crankshafts, in which contour checking, in particular roundness checking of workpieces and possibly also the stroke height of big-end bearing journals of crankshafts is effected quickly and accurately and the operation of ascertaining correction values for the tools and angular association thereof is very simple, wherein by means of a measuring sensor the maximum actual spacing of the workpiece contour to be measured in a measuring direction from a reference value, for example the turning center, is ascertained for each measurement angular position of the workpiece, the measured deviation between the actual spacing and the reference spacing is ascertained for each measurement angular position, and at least for the measurement angular positions the respective tool reference positions are automatically corrected by a correction value which is automatically calculated from the respective measured deviation. |
