BS 2518-2:1977

This standard BS 2518-2:1977 Specification for rotary form relieved gear cutters is classified in these ICS categories:

• 25.100.99 Other cutting tools
• 21.200 Gears

This Part of BS 2518 specifies certain dimensions for rotary form relieved gear cutters for milling spur and helical gears within the range 1 to 25 metric module.

Such cutters are deemed satisfactory for cutting gears intended to mesh together under conditions of service which are not critical.

NOTE It is not recommended that cutters designed in accordance with this standard be used for milling gears intended to mesh with generated gears. Where, however, it is found necessary to do this, a reduction in chordal thickness of the gear teeth is essential. (See Appendix A.)
