This part of ISO 14649 specifies the data elements describing cutting tool data for turning machine tools and machining centres. They work together with ISO 14649-12, the process data for turning machine tools and machining centres. These data elements can be used as criteria to select one of several operations; they do not describe a complete information of a particular tool. Thus, leaving out optional attributes gives the controller more freedom to select from a larger set of tools.Note 1 The NC is assumed to have access to complete description of specific tools in a database. The turning_machine_tool_schema defined in this part of ISO 14649 serves as a basic tool schema including the information required by the CNC to select a tool from the machine tool's tool turret.Note 2 In ISO 6983, the tool is defined by its identifier (e.g. T8). No further information concerning the tool type or geometry is given. This information is part of the tool set-up sheet, which is supplied with the NC-program to the machine. The tool set-up sheet gives the relationship between the tool location (e.g. the slot 8 of the tool magazine) and the type of tool (e.g. "drill 4 mm").This part of ISO 14649 includes the information which is contained in the tool set-up sheet:·tool identifier;·tool type;·tool geometry;·application dependent expected tool life.The turning_machine_tool_schema does not include information which is part of the tool database. The tool database is related to the machine tool and the tool itself but independent of the NC program. The following data types are out of scope of this part of ISO 14649:·normative tool life;·tool location in the tool changer;·adaptive items also know as tool holders or tool clamping devices;·tools for other technologies such as milling, grinding, EDM.Note 3 It is important to understand that all length measure types used in this part of ISO 14649 are not toleranced length measure types because they are used to describe the tools required for the manufacturing of a workpiece, not the actual dimensions of the tools available at the machine. A real tool must be selected by the tool management based on the actual tool dimensions and the tolerances of features.
