2. FUNCTION TO SIMPLIFY
(For the Power Mate i–D/D2)
This cycle is used for normal drilling.
Cutting feed is performed to the bottom of the hole. At the bottom, a dwell
is performed, then the tool is retracted in rapid traverse.
This cycle is used to drill holes more accurately with respect to depth.
G82 X_ Z_ R_ P_ F_ ;
X_ : Hole position data
Z_ : The distance from point R to the bottom of the hole
R_ : The distance from the initial level to point R level
P_ : Dwell time at the bottom of a hole
F_ : Cutting feed rate
After positioning along the X–axis, rapid traverse is performed to point
Drilling is then performed from point R to point Z.
When the bottom of the hole has been reached, a dwell is performed. The
tool is then retracted in rapid traverse.
Before specifying G82, use a miscellaneous function (M code) to rotate
When the G82 command and an M code are specified in the same block,
the M code is executed at the time of the first positioning operation. The
system then proceeds to the next drilling operation.
When a tool length offset (G43, G44, or G49) is specified in the canned
cycle, the offset is applied at the time of positioning to point R.
