G84 X __ Y__ Z___ R__ P__ F__ K__
X__ Y__ = Hole Position
Z__ = Distance from Z=0 plane to bottom of hole (negative)
Note: You Can Not Tap to the Bottom of a blind Hole
R__ = Distance from Z = 0 to clearance plane
F__ = Cutting feed rate
Feed Rate Must be Specified in Inches Per Revolution. (G95) How would determine the feed rate?
K__ = Number of repeats
Related Codes
G98 = Return to initial point in canned cycle
G99 = Return to R point in canned cycle
Note: G98 or G99 must be called out before G84
