ISO/TS 13399-309:2016

Overview

ISO/TS 13399-309:2016 - Cutting tool data representation and exchange - Part 309 defines a standardized concept for designing and exchanging simplified 3D models of tool holders for indexable inserts (turning tools). This Technical Specification specifies how to represent the design features, dimensions and descriptive properties of turning tool holders, and how to structure the internal data of 3D models so they can be used consistently across CAD/CAM and tooling systems.

Key aims:

• Provide a common model structure for tool holders that accept indexable inserts.
• Define feature identification and mapping to descriptive properties and dimensions.
• Promote interoperable cutting tool data exchange between manufacturers, CAD/CAM systems and tool libraries.

Note: the document does not cover storage/application mechanisms for the data, nor 3D model concepts for cutting items, other tool items, adaptive items, assemblies or auxiliary items.

Key Topics and Requirements

• Reference systems and coordinate definitions: Primary Coordinate System (PCS), tool item positions (prismatic and round), and key planes used for model positioning.
• Cutting Reference Point (CRP): definition and placement rules for consistent machining reference.
• Pocket seat design: rules for designing the insert pocket and associated geometry in the model.
• Model internal structure: how features are identified in the 3D model and linked to descriptive properties and dimensions.
• Necessary parameters and properties: required parameters for connection interfaces, insert types (equilateral, non-equilateral, round), and pocket seat properties.
• Tool types covered: long/ transverse turning holders, boring bars (ID/OD), threading tools, grooving and parting tools, pull-back designs, and various system tool assemblies.
• Geometry and assembly guidance: basic geometry, top-surface offsets, and assembly-specific feature definitions.

Applications and Who Uses It

ISO/TS 13399-309:2016 is practical for:

• Tool manufacturers creating standardized 3D tool holder models for catalogs.
• CAD/CAM engineers who need accurate tool definitions for simulation, collision checking and toolpath generation.
• CAM software vendors and tool library developers implementing interoperable tool data exchange.
• Manufacturing engineers and machine tool builders standardizing tooling data for production planning. Benefits include reduced CAM setup errors, improved interoperability of tool libraries, consistent simulation and better integration between tool design and production systems.
