ADTECH9 Series CNC Programming Manual
Effect of G98/G99 on Hole Processing
Meaning
Specify the position of the hole being processing in increment or
absolute mode; the track and speed of the tool moving to processed
hole are same to G00
In absolute value mode, specify the position of hole bottom in Z
axis direction; in increment value mode, specify the distance from
point R to hole bottom
In absolute value mode, specify the position of point R in Z axis
direction; in increment value mode, specify the distance from the
start point to point R
Used to specify the tool feeding of deep hole drilling cycle G73 and
G83, and the offset of fine boring cycle G76 and reverse boring
cycle G87 (always increment value instruction no matter G90 or
G91 mode)
Used to specify the pause time (unit: sec) in the fixed cycle that hole
bottom action has pause
Used to specify the cutting feeding speed in fixed cycle; in the fixed
cycle, the motion from start point to point R and from point R to
start point executes in the speed of quick feeding, the motion from
point R to point Z executes in the cutting feeding speed specified by
F, while the motion from point Z to point R executes either in the
speed specified by F or quick feeding speed.
