13.2.5 Three-dimensional rigid tapping
When the machine is provided with axes for swiveling the tool, this
function allows rigid tapping in the direction in which the tool is
pointing after the tool is swiveled about the specified axes. This three-
dimensional rigid tapping function must be used together with the
three- dimensional coordinate conversion function (G68) .
Format
The command for three- dimensional rigid tapping is specified in the
same format as for usual rigid tapping.
Limitation
The limitations set for the rigid tapping cycle and reverse rigid tapping
cycle apply.
