Function
G76 mill control types.
G86.1 lathe control types.
This parameter specifies whether the distance of a cutting tool shift during
a fine boring cycle is determined by a programmed Q-word on an AMP
assigned axis or if the distance is set with I, J, K, words in the currently
active plane.
YES -- Setting a value of “YES” for this parameter allows the
programming of a Q-word to specify the distance of the shift in the block
that calls the fine boring cycle. The axis and direction that the shift uses is
determined by the AMP parameters discussed in section titled “Fine
Boring Shift Direction.”
NO -- Setting a value of “NO” for this parameter causes the value set for
the axis and direction of shift using the parameters discussed in section
25.1.3 to be ignored. It is necessary to program the shift amount, direction,
and axes for the shift, using I, J, and K words in the block that calls the
fine boring cycle.
