This document specifies a reference dictionary for tool items, together with their descriptive properties and domains of values. This document specifies a reference dictionary containing: —    definitions and identifications of the classes of tool items and their features, with an associated classification scheme; —    definitions and identifications of the data element types that represents the properties of tool items and their features; —    definitions and identifications of domains of values for describing the above-mentioned data element types. The following are within the scope of this document: —    standard data that represent the various classes of tool items and tool item features; —    standard data that represent the various properties of tool items and tool item features; —    standard data that represent domains of values used for properties of tool items and tool item features; —    definition of cutting operations; —    definitions of reference systems for tool items and their properties; —    one implementation method by which the standard data defined in this document can be exchanged. NOTE 1    The implementation method by which the standard data defined in this document can be exchanged is specified in ISO 10303-21. The following are outside the scope of this document: —    specialized or expert knowledge in the design and use of cutting tools; —    rules to determine what information should be communicated; —    applications where these standard data can be stored or referenced; —    implementation methods other than the one defined in this document by which the standard data can be exchanged and referenced; —    information model for cutting tools; —    definitions of classes and properties for cutting items; —    definitions of classes and properties for adaptive items; —    definitions of classes and properties for assembly items; —    definitions of classes and properties for connection systems; —    definitions of classes and properties for reference systems. NOTE 2    The information model for cutting tools is defined in ISO 13399-1. NOTE 3    The definitions of classes and properties for cutting items, adaptive items, and assembly items are provided in ISO/TS 13399-2, ISO/TS 13399-4, and ISO/TS 13399-5, respectively. NOTE 4    The definitions of classes and properties for connection systems and reference systems are provided in ISO/TS 13399-50.
