This document defines the OPC UA Information Model for the exchange of production and geometry data for the manufacturing of cylindrical cutting tools e.g., endmills, drills and reamers. The interface is to be used for tool grinding machines, laser tool manufacturing, erosion machines, measuring machines and higher-level IT systems. At the same time, existing specifications such as Machinery, Machine Tools or Geometrical Measuring Systems are used in the context for this definition. The description of the geometry data is taken from the VDMA specification series-VDMA 34189 but is only used as a file in the context of this specification.
