necessary hole processing parameters except F must be re-specified,
even if these parameters aren’t changed.
7
X_Z_
X axis positions the instruction point and processes the hole, and hole
processing parameter Z is changed in this segment.
8
G89X_Y_
Position the XY instruction point and process the hole, and the hole
processing mode is changed to G98. R, P are specified by 7, and Z is
specified by 7.
9
G01X_Y_
The fixed cycle mode is canceled, and all hole processing parameters
except F are canceled.
In the following diagrams, we use the modes below to indicate the feeding of every segment:
Indicate motion in quick feeding speed
Indicate motion in cutting feeding speed

The feeding from point R to point Z is finished in several segments; after cutting every segment, Z axis lifts for
certain distance, and then executes cutting feeding for next segment.
The distance that Z axis lifts every time is d, which is specified by parameter P1.015,G73(M)circulating tool
