Discussion in the shop today.
Fanuc G84 tapping = tool comes down to work, feeds in at rate calculated to
be correct lead for RPM, spindle reverses and tool comes back out.
Fanuc G84 Rigid Tapping = tool comes down to work, spindle stops and
orients itself, feeds down, spindle stops(dwell can be programmed: why?),
spindle reverses and tool feeds out. Retract rate can be set by parameter
to be as much as 4x the infeed.
For general tapping (a number of average, meaning no more than 3x tap dia,
thru holes or blind holes with plenty of room for chips) what would be the
advantage of one cycle over the other?
