General Considerations
* When the machine uses rigid tapping "P63(3)=1" the spindle control is done in
closed loop.
* To switch it to open loop, G80 must be executed.
From this point on, the spindle control is done in open loop and it is possible to
program the "S" function.
Function G80 must be programmed alone in the block.
* The spindle will operate in closed loop again, if G84 is programmed, on power-
up, after executing an M30 or after an Emergency or Reset.
* The spindle turning direction during rigid tapping must be defined before function
G84 and by means of M3, M4.
If when executing G84, no turning direction has been selected, the CNC assumes
the M03 (clockwise).
* All the various movements involved in rigid tapping are treated as a single block.
In other words, when executing a G84 cycle in the Single-Block, the CNC makes
the whole tap.
* When executing function G84, the CNC assumes functions G01 and G07.
* If due to possible spindle backlash, an additional spindle rotation is required at the
bottom of the tap, it must be indicated by arithmetic parameter P19 in the number
of spindle encoder pulses to move.
The CNC recovers this additional movement by rotating in the opposite direction
at the end of the tap.
* A dwell at the bottom of the tap is also possible by indicating it, in milliseconds,
with machine parameter "P32".
