1.2 HOLE MACHINING BY TURNING (WITH THE TOOL
ROTATED)
1.2.1 Machining Type Blocks for Hole Machining by Turning (with
the Tool Rotated)
NOTE
1 Hole machining by turning (with the tool rotated) is
enabled when bit 1 of parameter No. 27000 = 1.
2 The hole position blocks for hole machining by
turning (with the tool rotated) are the same as
those for hole machining by milling. See the
previous section (Hole Position Block).
Center drilling: G1110
Cutting condition
Data item Meaning
I REF.PT.MODE [INIT-1] : An R position return is made in moving
between holes. Finally, a return is made to
the I point. (initial value)
[INITI-2]: All movements between holes, including
the last return, are made as an I point
return.
[REF.] : All movements between holes, including
the last return, are made as an R position
return.
J I POINT Coordinate of the I point (COPY)
L CUT DEPTH Cut depth (radius value, negative value)
C CLEARANCE Distance between the workpiece surface and R
position (radius value, positive value) (COPY)
F FEED RATE Cutting feedrate (positive value) (COPY)
P* DWELL TIME Dwell time at the hole bottom (units of seconds,
positive value). (COPY)
