This part of ISO 14649 specifies the data elements describing cutting tool data for milling machine tools andmachining centres, which work together with the process data for milling machine tools and machining centresspecified in ISO 14649-11. They can be used as criteria for selecting one of several operations; they do notdescribe complete information on a particular tool. Therefore, leaving out optional attributes gives thecontroller more freedom to select from a larger set of tools.NOTE 1 The numerical control (NC) is assumed to have access to complete description of specific tools in a database.The milling_machine_tool_schema defined in this part of ISO 14649 serves as a basic tool schema, including theinformation required by the CNC to select a tool from the machine tool's tool magazine.NOTE 2 In ISO 6983, the tool is defined by its identifier (e.g. “T8”). No further information concerning the tool type orgeometry 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. “slot 8 of the tool magazine”) and the type oftool (e.g. “drill 4 mm”).This part of ISO 14649 also specifies the information to be provided in the tool set-up sheet:- tool identifier;- tool type;- tool geometry;- application-dependent expected tool life.The milling_machine_tool_schema does not include information which is part of the tool database. The tooldatabase is related to the machine tool and the tool itself, but is independent of the NC program. The followingdata types are outside the 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 turning, grinding and electrical discharge machining (EDM)NOTE 3 It is important to understand that all length measure types used in this part of ISO 14649 are not tolerancedlength measure types because they are used to describe the tools required for the manufacturing of a workpiece, not theactual dimensions of the tools available at the machine. A real tool will be selected by the tool management based on theactual tool dimensions and the tolerances of features.This part of ISO 14649 uses the EXPRESS language as specified in ISO 10303-11.
