Machining formulas and definitions

Cutting tool parameters according to ISO 13399

All cutting tools are defined by a number of parameters according to the standard ISO 13399. You find both the cutting tool parameter and its definition in this list.

What is ISO 13399?

ISO 13399 is an international cutting tool information standard. Each cutting tool is defined by a number of these standardized ISO 13399 parameters. The standard provides cutting tool information in a neutral format that is independent of any particular system or company nomenclature. With tools that are clearly defined according to a standard that all software can process, the quality of communication gets better and the electronic data exchange between systems runs smoothly. The data gathering process will be more efficient and of higher quality. Ultimately, the standard saves time and gives an extra guarantee of quality. A common language is valuable from a system to system point of view, but will also make life easier for users. Once you have an ISO13399 compliant system, there will be no need to manually interpret data from paper catalogues and then key-enter it into your system.
