This standard deals with the principle hazards arising from use of milling cutters, e.g. milling cutters according to ISO 3855, used for high speed machining (chip removal machining at increased peripheral speeds) on metal working machine tools and prescribes safety requirements. It specifies design methods, centrifugal force test procedures, operational limits and the provision of information that will lead to minimisation or elimination of these hazards. The standard is applicable to milling cutters which are intended for operation at speeds in accordance with figures 1 and 2. These figures respectively define the rotational speed limits and peripheral speed limits for specific cutter diameters. NOTE A detailed explanation is provided in annex B.
