Basic Theory
Frequently used letter meanings of typical fixed cycle codes in ISO mode.
P. Descriptions
X/Y Cutting end point X/Z absolute
coordinate values
The distance incremental value
between R point and the bottom of the
Z
hole, or the absolute coordinate value
of the bottom of the hole
The distance incremental value
between the start point plane and R
R
point or the absolute coordinate value
of R point
The depth of every cut
Q （incremental value）
Offset value
（incremental value）
P The delay time at the bottom of the
hole
F The feedrate of the cutting
K The repeat times of the fixed cycle
In 808D, the default ISO program feed distance unit is mm!
(X100→100mm)
Note: change the parameter 10884 = 0, to make X100

G73 fast-speed deep hole drilling
Common programming structures:
G73 X—Y—Z—R—Q—F—K
Motion process:
①
Drilling motion (-Z) → intermediate
feed
②
Motion at the bottom of the hole →
none
③
Retraction motion (+Z) → fast feed
G74 reverse tapping cycle
Common programming structures:
G74 X—Y—Z—R—P—F—K
Motion process:
①
Drilling motion(-Z) → cutting feed
②
Motion at the bottom of the hole →
spindle rotation in positive direction
③
Retraction motion(+Z) → cutting feed
