ISO 13399 (Cutting tool data representation and exchange) is an international technical standard by ISO (the International Organization for Standardization) for the computer-interpretable representation and exchange of industrial product data about cutting tools and toolholders. The objective is to provide a mechanism capable of describing product data regarding cutting tools, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange (free of proprietary format constraints), but also as a basis for implementing and sharing product databases and archiving, regarding cutting tools.
