1. The description of "Thread lead" on "14.2.1 Rigid tapping (G84)" is replaced
as follows.
Thread lead
In feed-per-minute mode, the thread lead is obtained from the
expression, feedrate÷spindle speed. In feed-per-revolution mode, the
thread lead equals the feedrate speed.
If a tool length offset (G43,G44 or G49) is specified in the canned
cycle, the offset is applied at the time of positioning to point R.
