1 Scope
This part of ISO 14649 specifies the data elements describing cutting tool data for milling machine tools
and machining centres, which work together with the process data for milling machine
tools and machining centres specified in ISO 14649‑11. They can be used as criteria for selecting one of several operations; they do not
describe complete information on a particular tool. Therefore, leaving out optional
attributes gives the controller 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 the information 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 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. “slot 8 of the tool magazine”) and
the type of tool (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;
—
