Machine Tool and Method for Preparing a Machining of a Material-removing Rotary Tool

A machine tool (10) which is configured to machine a material-removing rotary tool (13) with use of at least one tool (12), which rotary tool comprises a tool body (34) extending along a tool longitudinal axis (L) and at least one cutting body (35) which is fastened to the tool body (34), said machine tool comprising:

• a detector (27) connected to a controller (25) for capturing detection data of the rotary tool (13) to identify a transition point between the tool body (34) and the at least one cutting body (35), and
• a clamping device (14) which is configured to clamp the rotary tool (13) for machining with the at least one tool (12),
• wherein the controller (25) is configured to control an axis arrangement (11) of the machine tool (10) so as to move the at least one tool (12) of the machine tool (10) and the clamping device (14) for the rotary tool (13) to be machined relative to one another and so as to position the at least one tool (12) of the machine tool (10) and the clamping device (14) for the rotary tool (13) to be machined relative to a machine coordinate system (M) of the machine tool (10),
• and wherein the controller (25) is configured to determine at least one coordinate value (z1, z2, α1, α2) for each of the at least one cutting body (35) arranged on the tool body (34) on the basis of the detection data, wherein the at least one coordinate value (z1, z2, α1, α2) describes an edge position of an edge (45, 46) of a cutting body (35) in relation to a reference coordinate system (K) of the rotary tool (13),
• wherein the controller (25) is configured to carry out machining of the at least one cutting body (35) by the at least one tool (12) under consideration of the at least one coordinate value (α1, α2) and/or to determine at least one further or more precise coordinate value (r, α1, α2, z1*, z2*) of the at least one cutting body (35) under consideration of the at least one coordinate value (z1, z2) obtained by the evaluation of the detection data.
