A tool insert for a machine, in particular a cutting, punching and/or folding machine, is disclosed. The tool insert (24) has an identification element (38) comprising tool information about the type of the tool insert (24) and/or about the area of application of the tool insert (24). The identification element (38) is machine-readable such that the tool information is transmitted to the machine when the machine reads out the identification element. Further, a machine, a machine system and a method for operating a machine are disclosed.

A method for generating control command data for controlling a CNC-lathe to perform a turning operation by means of a turning tool. The method includes the steps of generating control command data for commanding the turning tool to perform a first turning pass and a second turning pass, wherein a maximum cutting depth of the second turning pass is greater than a maximum cutting depth of the first turning pass.

A method for generating control command data for controlling a CNC-lathe to perform a turning operation by means of a turning tool. The method includes the steps of: generating control command data for commanding the turning tool to go into cut at a point of the unmachined inner surface, which is most far away from the end position; and commanding the turning tool to move along the inner surface towards the end position until either: the turning tool reaches the end position, or a cutting depth is equal to or greater than one of either: the maximum allowed cutting depth or the recommended cutting depth, whereby the turning tool is commanded to move away from the inner surface; or the turning tool reaches a predefined position, whereby the turning tool is commanded to move away from the inner surface.

A tool management system of machine tools includes a reader, a receiver, a storage unit, a processor and a control unit. The reader is configured for reading at least one category parameter of the tool according to a tool index code of the tool. The receiver is configured for receiving real-time process information of the tool with a preset periodicity. The storage unit is configured for storing the tool index code, the category parameter, and the real-time process information. The processor is configured for processing a weighting algorithm to obtain a result according to the category parameter and the real-time process information. The control unit is configured for sending a control instruction according to the result.
