Werkzeugnummer

Werkzeugnummer is a term used in manufacturing to denote a unique identifier assigned to a tool (Werkzeug) within a company’s tool management system. It refers to the specific tool, insert, holder, or forming die that is used in production equipment such as CNC machines, stamping presses, or molding machines. The purpose is to enable precise identification, tracking of wear and replacement needs, and efficient ordering and inventory control.

In practice, the Werkzeugnummer links to a set of tool attributes, including tool category (for example drill, end mill, insert, or punch), geometry, coating, holder type, and key physical parameters like diameter and length. It also connects to supplier data and enables quick cross-referencing in maintenance records, tool-life tracking, and production planning. Operators and programmers use the Werkzeugnummer in CNC programs and tool lists to ensure the correct tool is loaded and used.

There is no universal format for Werkzeugnummer; formats vary by company and supplier. Codes can be numeric or alphanumeric and may embed information such as category, size, or revision, or merely serve as an internal index. Many organizations maintain a separate part number (Teilenummer or Teilnummer) and a separate order or purchase number (Bestell- oder Bestellnummer) to facilitate procurement. While international standards such as ISO 13399 exist to standardize the description of tool data, the actual Werkzeugnummer is typically an internal identifier used across databases, catalogs, and ERP systems.

In summary, the Werkzeugnummer is a practical tool-identification mechanism that supports tool lifecycle management, procurement, and production accuracy within modern manufacturing environments.
