Tool management is mainly interested in where a wanted component currently is, and at what cost center it is consumed. This method only consumes wear parts (cutting), the other components (holders, clamping devices) are moved between toolroom, storage places and machine tool. Component booking at the individual cost centers and locations occurs simultaneously when withdrawn/restored to the toolroom. The preparation of tools and resources is triggered by a production order. It refers to a tool list in the master data, that lists required components. Prior to usage in the machine tool, the components are assembled, according to the specifications and work instructions
