Overview

EN ISO 15641:2001 - Milling cutters for high speed machining - Safety requirements specifies safety requirements for milling cutters used in high speed machining (chip removal at increased peripheral speeds) on metalworking machine tools. The standard addresses principle hazards from high rotational energy, prescribes design methods, centrifugal force test procedures, operational limits, and the required information for use to minimise or eliminate risks. It applies to cutters intended to operate within the rotational speed and peripheral speed limits shown in the standard’s figures (see figures 1 and 2). Informative annexes provide design guidance (Annex A) and scope explanation (Annex B).

Key topics and technical requirements

  • Scope & applicability: Covers solid (one‑piece), composite (bonded), and complex (mechanically fastened) milling cutters intended for high speed machining.
  • Hazard analysis: Identifies primary hazards (centrifugal forces, burst risk, released component energies) and handling hazards (mounting, dismounting, transport).
  • Design principles: Tools must be designed to resist centrifugal loads; calculation is allowed for geometrically similar product lines if validated by testing.
  • Speed safety factor: Manufacturer’s maximum rotational speed (nmax) must be verified with a rotational speed safety factor of 2, giving a centrifugal force safety factor of 4:1 (with reference to clause 5.4.3).
  • Centrifugal force type testing: Specifies general test requirements and separate test procedures for solid/composite and complex cutters, including test duration and test rotational speed determination.
  • Key parameters and terminology: Defines terms like maximum diameter (D), critical diameter for bending (d), protruding length (lp), tool mass (mw), component masses (mt), and nmax.
  • Balance and manufacturing integrity: Emphasises balance quality, manufacturing integrity and correct fixing types (bonding, friction lock, form lock, separable).
  • Marking & documentation: Requires marking, user instructions, and application information (limits, mounting, drive/clamping, coolant/air considerations).

Applications and users

EN ISO 15641:2001 is intended for:

  • Tool designers and manufacturers - to design and validate milling cutters for high speed use.
  • Suppliers and distributors - to provide correct marking and documentation.
  • Machine builders and safety engineers - to assess tool compatibility with machine speed limits and guarding.
  • Shop floor managers and machinists - to select compliant cutters and follow operational limits and mounting instructions.

Note: This tool standard addresses tool safety but does not alone ensure complete machine safety - machine-specific safety standards must also be followed.
