Grinding and/or erosion machine

System (33) comprising a setup and/or measuring machine (34) that is configured to determine position data, as well as comprising a grinding and/or erosion machine (10) that is configured to machine a chip-cutting rotary tool (13), that comprises a tool body (18) extending along a tool longitudinal axis (L), and having several cutting plates (19) per existing pitch (TR), said cutting plates being mounted to the tool body (18), wherein the machine comprises:

• a control device (25) configured to activate an axis arrangement (11) of the grinding and/or erosion machine (10) in order to move a machine tool (12) of the grinding and/or erosion machine (10) and the rotary tool (13) to be machined relative to each other,
• an interface device (26) that is communicatively connected to the control device (25), wherein a user is able to use the interface device (26) to trigger a data import function of the control device (25) for reading-in position data of the cutting plates (19) into an imported machine data set (M),
• wherein the position data (P) for each of the cutting plates (19) comprise at least one angular value (α1, α2) describing an angular position about the tool longitudinal axis (L), a first length value (z1) and a second length value (z2), wherein the first length value (z1) describes an edge position of a first edge (37) of a respective cutting plate (19) of the cutting plates (19) in a direction parallel to the tool longitudinal axis (L), and wherein the second length value (z2) describes an edge position of a second edge (38) of the respective cutting plate (19) in a direction parallel to the tool longitudinal axis (L), said second edge being opposite the first edge (37),
• wherein the control device (25) is configured to import the position data (P) during the data import function in chaotic order and to allocate the position data (P) of each of the cutting plates (19) in the imported machine data set (M) respectively to a separate virtual pitch (TV), independent of whether or not the cutting plates (19) do in fact belong or not belong to a common pitch of the rotary tool (13).
