This MD defines which angular range the tool radius compensation recognizes as the
tangential transition (180° ± MD 331). No intermediate blocks are inserted with tangential
transitions.

With the "Dwell referred to an axis" (G24), a time corresponding to the machine data above is
compensated statically. This data is used to observe the internal execution times in the control.
If the value is 0, there is no deadtime compensation.
With dwell on absolute position (G90) the speed of the axis/spindle must not become
greater than Dmax, so that overtravel of the dwell position is recognized reliably.
If the speed is greater than or equal to D

dead
Example of standard machine data:
Tab = 16 ms, K
D < 30000/(16 *(1+4.5)) rpm = 340 rpm
