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 deflection 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). widia.com Y81 High-Performance Thread Mills
