Grinding and/or Eroding Machine, and Method for Measuring and/or Referencing the Machine
The invention relates to a grinding and/or erosion machine (10), as well as to a method for gauging and referencing the axis arrangement (11) comprising several machine axes (12), wherein each can be configured as a rotational or translational machine axis. To do so, a measuring disk (28) is inserted in a tool spindle (13) and a test mandrel (27) is inserted in a workpiece holding device (14). The test mandrel (27) is electrically connected to a reference potential, preferably ground (M). The measuring disk (28) is electrically connected to a supply voltage potential (UV). By forming a contact between the measuring disk (28) and the test mandrel (27), a measuring current (IM) flows between the supply voltage potential (UV) and the reference potential and, in accordance with the example, from the supply voltage potential (UV) to ground (M). The flow of this measuring current (IM) may be detected in a monitoring device (31), and the actual position of the machine axes (12) at the time of the start of the current flow of the measuring current (IM) can be determined. Via the axis arrangement (11), one or more contact locations (K) between the measuring disk (28) and the test mandrel (27) can be approached, and, as a result of this, referencing or gauging of the axis arrangement (11) and the machine, respectively, can take place.
Grinding and/or erosion machine
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 (1, 2), a first length value (z1) and a second length value (z2). 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).
