NOTES:
1 The cutter radius measured over the tooth crests of the threaded part must be reduced by the amount of the cutter radius compensation. This is necessary to achieve a depth of cut to the middle
of the 6H/ISO2 nut tolerance. Please note, however, that this also depends on the radial deection of the tool (tensile strength of the material, projecting length of the tool).
2 The cutter radius to be programmed is normally included in the tool memory.
3 The thread depth b must be divisible by the thread pitch P.
4 The feed values in brackets must be used for controllers, which do not calculate the centre point feed themselves.
5 Set N40 must be repeated with the number of threads. Repetitions N = thread depth b/pitch P (rounded up to the nearest integer).
