Abstract

Grinding and/or erosion machine ( 10 ) for machining a chip-cutting rotary tool including a tool body ( 18 ) and several cutting plates ( 19 ) per existing pitch (TR). A control device ( 25 ) activates an axis arrangement ( 11 ) to move a machine tool ( 12 ) and the rotary tool ( 13 ) to be machined relative to each other. An interface device ( 26 ) triggers a data import function for reading-in the position data of the cutting plates ( 19 ). The position data (P) describe at least one angular value (α 1, α2 ), a first length value (z 1 ) and a second length value (z 2 ). The control device ( 25 ) imports the position data (P) in chaotic order and allocates the position data (P) of each cutting plate ( 19 ) in the imported machine data set (M) to respectively one separate virtual pitch (TV), independent of whether the cutting plates ( 19 ) belong to a common pitch of the rotary tool ( 13 ).

6. Grinding and/or erosion machine according to claim 5 , wherein the probe device ( 27 ) is configured to probe an edge ( 37 , 38 , 39 ) and/or a surface ( 41 ) of one of the cutting plates ( 19 ) at at least one probing point (A 1 , A 2 , A 3 ) in a contacting or contactless manner.

7. Grinding and/or erosion machine according to claim 6 , wherein the control device ( 25 ) is configured to calculate several probing points (A 1 , A 2 , A 3 ) on each of the cutting plates ( 19 ) based on the imported position data (P).

8. Grinding and/or erosion machine according to claim 7 , wherein the probing points (A 1 , A 2 , A 3 ) are located on a common flat surface ( 41 ) of the respective cutting plate ( 19 ).

9. Grinding and/or erosion machine according to claim 7 , wherein the control device ( 25 ) is configured to activate the axis arrangement ( 11 ) so that the probe device ( 27 ) is able to probe each cutting plate ( 19 ) in sequence at the calculated probing points (A 1 , A 2 , A 3 ).

10. Grinding and/or erosion machine according to claim 9 , wherein the control device ( 25 ) is configured to determine the alignment of each of the cutting plates ( 19 ) relative to a reference coordinate system (K).
