Overview
ISO/TS 13399-302:2013 - Cutting tool data representation and exchange (Part 302) - defines a concept for designing simplified 3D models of solid drills and countersinking tools based on the property model in ISO/TS 13399-3. The technical specification standardizes how design features, internal model structure and associated property domains are represented to enable consistent cutting tool data representation and exchange across CAD/CAM/PLM systems.
Key topics and technical requirements
- Modeling concept: A common approach for creating simplified 3D models that link geometric features to standardized properties and value domains from ISO/TS 13399-3.
- Feature definitions & IDs: Definitions and identifications of design features for drills and countersinking tools with solid cutting edges.
- Internal model structure: Rules for the internal structure of 3D models to represent features and properties reliably (model tree, feature hierarchy).
- Coordinate systems & datum: Specification of reference and machine coordinate systems, planes and the Cutting Reference Point (CRP) for consistent placement and orientation.
- Connection interface: Required parameters and geometry for non-cutting parts including tool shanks and connection interfaces.
- Tool-specific geometry: Geometry and property requirements for many tool types, including: twist drills, step drills, core drills, counterbores, stepped/tapered countersinks, spot drills, centre drills, shell tools and guide pilots.
- Surface attributes & visualization: Guidance on attributes for surfaces and how model features should be visualized.
- Data exchange model: Structure for exchanging these simplified models between systems to support interoperability.
Applications and who uses it
ISO/TS 13399-302 is intended for organizations and professionals involved in the digital representation and exchange of cutting tool data:
- Tool manufacturers creating catalog models and digital product data.
- CAD/CAM/PLM developers implementing standardized tool libraries and import/export routines.
- CNC programmers and manufacturing engineers who rely on accurate tool geometry and properties for process planning and simulation.
- Tool distributors and inventory/PDM systems that exchange tool data between suppliers and users.
The specification supports interoperability, reduces ambiguity in tool models, and enables reliable downstream uses such as toolpath generation, collision checking, and tooling automation.
