•
R—finish allowance. This is the amount of material to leave for the finish
pass.
•
X(u)—minimum diameter for the thread depth.
•
Z(w)—Z end position of the cycle.
•
R—second line with R is start thread radius minus end thread radius.
•
P—second line with P is thread height.
•
Q—second line with Q is depth of cut for the first pass.
•
F—thread lead.
Example
The following figure illustrates G76:

The retract move is approximately 45
°
or less depending upon servo
lag.
1
