2. FUNCTION TO SIMPLIFY
(For the Power Mate i–D/D2)
This cycle is used to bore a hole.
G85 X_ Z_ R_ 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
F_ : Cutting feed rate
After positioning along the X– axis, rapid traverse is performed to point
Drilling is performed from point R to point Z.
When point Z has been reached, cutting feed is performed to return to
Before specifying G85, use a miscellaneous function (M code) to rotate
When the G85 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.
