Measure tool with toolholder that can be orientated

Overview
The functionality is designed for a specific configuration on turning machines (turning/milling
machines). As well as the linear axes (Z and X) and main spindle, the turning machines must
have swivel axis about Y with accompanying tool spindle. The swivel axis can be used to
align the tool on the X/Z level.
Preconditions
● The lateral surfaces of the tool probe should be aligned parallel to the relevant axes
● The tool to be measured must be active with its tool offset values when the cycle is
● When measuring turning tools, the cutting edge position of the tool must be entered in the
● When measuring drilling and milling tools, the setting data must be
● The active level must be G18.
Function
To take into account the tool carrier that can be orientated in measuring cycle CYCLE982,
MD 51740 $MNS_MEA_FUNCTION_MASK bit16 must be set.

When measuring turning tools, especially roughers, finishers and mushroom-shaped tools,
the swivel axis can assume any position around Y. Multiples of 90° are permitted for milling
and drilling tools. Multiples of 180° are possible when positioning the tool spindle.
This is monitored within the cycle.
If turning tools are measured around Y using any positions (not multiples of 90°) of the swivel
axis, then it should be taken into consideration that the turning tool is measured with the
same tool position in both axes X/Z, assuming that this is possible.
