An apparatus for machining a workpiece comprises means for clamping the workpiece, means for rotatingly driving the clamped workpiece, a tool for machining the workpiece, the tool having a part for engaging the workpiece, a tool holder, means for moving the tool holder with respect to the clamping means and a control unit with a memory for one or more control programs. The control unit is arranged to control the moving means according to a control program by means of measuring means providing the x,y-positions of the tool holder in such a manner that the tool follows a desired path along the clamping means for machining the workpiece. The apparatus comprises a measuring device located at a predetermined reference position with respect to the moving means. The control unit is arranged to control the moving means in such a manner that said tool part is moved along to the measuring device, wherein the measuring device delivers a measuring signal to the control unit, wherein the control unit determines the shape of said tool part and the position thereof with respect to the tool holder directly from the x,y-positions provided by the x,y-measuring means and stores these x,y-positions in the memory for use in the (each) control program for the corresponding tool.

[ What is claimed is:] [1.] An apparatus for machining a workpiece, comprising means for clamping the workpiece, means for rotatingly driving the clamped workpiece, a tool for machining the workpiece, said tool having a part for engaging the workpiece, a tool holder, moving means for moving the tool
[ What is claimed is:] [1.] An apparatus for machining a workpiece, comprising means for clamping the workpiece, means for rotatingly driving the clamped workpiece, a tool for machining the workpiece, said tool having a part for engaging the workpiece, a tool holder, moving means for moving the tool holder with respect to the clamping means, measuring means for measuring the position of the tool holder in a x- and y-direction, and a control unit with a memory for at least one control program, in which one or more paths of movement of the tool holder are stored as x,y-positions therein, wherein the control unit is arranged to control the moving means according to the control program by means of the x,y-positions provided by said x,y-measuring means in such a manner that the tool follows a desired path, wherein a contour measuring device is disposed at a selected reference position with respect to the moving means for measuring a contour of said tool part, wherein the control unit is arranged to compare the contour with a previously stored contour of said tool part and wherein the control unit adapts each control program for the tool if differences are found, wherein for measuring the contour of said tool part, the control unit controls the moving means by means of the x,y-positions provided by the x,y-measuring means in such a manner that said tool part is moved with respect to the contour measuring device, wherein the control unit determines the contour of said tool part and the position thereof with respect to the tool holder directly from the x,y-positions received from the x,y-measuring means and stores said contour and position in the memory for use in the control program for the tool.
