Access standard tool data in ISO 13399 format

​​​​Create assemblies for documentation or process simulation more easily using standard tool data. The Sandvik Coromant ISO 13399 catalogue is compatible with any open tool library or tool management system supporting the international standard.

GTC (Generic Tool Catalog)​

The next step in tool-data communication

Tired of manual cutting-tool data handling? The new Generic Tool Catelog (GTC), developed by Sandvik Coromant and Siemens PLM, combined with the ISO 13399 standard enables user-friendly and uncomplicated communication of cutting-tool data. No manual data handling is required.

Sending and receiving tool data has always been a very manual process, often including reading from paper catalogs and manually putting cutting-tool data into tool libraries.

ISO 13399 – a new generic standard used to describe cutting tool product data where tools share the same properties and definitions – is a first step in addressing these issues. However, while ISO 13399 describes tools, it does not tell how to organize piecemeal individual tool date for a whole catalog communication. Luckily, GTC does.

The GTC format definition consists of two main parts: the GTC hierarchy and the GTC package structure.

The GTC hierarchy is a vendor neutral generic tool classification system based on ISO 13399. It uses commonly used denominations in the cutting tool industry to define tool kind, making it logical and easy to understand.

In addition to this, the GTC package structure defines the digital catalog content which organizes tool information (properties, 3D models, 2D drawings, etc) in a predefined computer interpretable format.

GTC is to be maintained by NTB Interstate University of Applied Sciences of Technology Buchs.

Benefits for you

By organizing tool data and making it searchable, GTC can reduce time spent on searching for tools and tool data. Consequently, cutting-tool vendors that use GTC will benefit greatly, saving both time and money. This easy to adopt catalog structure can eliminate previous problems with tool-data communication.

GTC is intended to be used as a hierarchical catalog structure for easy navigation and search, helping users to find the tools they are looking for. It also serves as a mean for correct mapping of data for data import functionality. Cutting tool vendors only have to make sure that their internal structures’ properties correspond to GTC’s properties. The product data is then available for quick download.

Usage areas

GTC is intended to be used as a hierarchical catalog structure for easy navigation and search, helping users to find the tools they are looking for. It also enables correct mapping of properties for data import functionality.

The GTC hierarchy should be used as a complement to ISO 13399. It is intended to:

  • Help pre-map classes and properties to receiving systems’ internal classifications and properties.
  • Be used as a generic hierarchical catalog structure for easy navigation and search.
  • Serve as a base structure for manually entering own defined or non-classified tools into a catalog.

GTC is primarily developed for environments where there is a great need of cutting-tool data. However, it can also be used in other business situations for other purposes. GTC supports different steps in the manufacturing process, e.g. CAM-systems, tool path simulation, shop floor management, inventory control, presetting, e-commerce and purchasing.
