Rigid mode
The deep-hole rigid tap cycle is selected as the infeed once Q
is instructed. It is
possible to select either of the 2 types by the parameter PCP (No5200#5).

High-Speed, Deep-Hole Rigid Tap Cycle (PCP = 0)
G74
Initial point
Bottom point of the hole
The amount of relief D is set by parameter (No. 5213). High-efficiency working
is possible since it is possible to set the amount of relief in micro amounts by
facilitating to discharge the cuttings of deep-hole drilling by intermittent feed in
the X-axis direction.
Withdrawing override is valid for relief. (Parameter No.
5200, 5211)
