APROCH MOTION
[2 AXES]
: When moving from the current position to

moves in the machining plane in two-axis
synchronous operation and then moves
along the tool axis. (initial value)
[3 AXES]
: The tool moves from the current position
to the machining start point in three-axis

Tool path
The side-face contour of pocket and island machining profiles is
finished. The tool path for it is the same as for contouring (side-face
finishing).
See descriptions about contouring (side-face finishing) for details.
The specifications for the following points differ in part, though.
No in-feed machining is performed in the tool radius direction or tool
axis direction.
Even if it is anticipated that the tool may interfere with a pocket or
island machining profile during finishing, no tool path that can avoid
interference is created.

The same fixed-figure block types as for the XY plane explained in
the previous subsection are available for the YZ plane and the XC
plane (polar coordinate interpolation plane). They are provided with
the following G codes.
The data to be set for the YZ and XC planes is the same as for the XY
plane except that the XY plane is changed to the YZ or XC plane and
that the direction in which the tool moves to cut is changed to the
X-axis (YZ plane) or the Z-axis (XC plane).

When performing machining (polar coordinate

The mode needs to be switched to the polar
coordinate interpolation mode beforehand.
Specifically, enter G12.1 before the machining
type.
Enter G13.1 for canceling polar coordinate
interpolation as required.
(When bit 2 of parameter No. 27000 = 1)
G12.1 and G13.1 are automatically output before

If there is a island, push the soft-key [ISLAND] in order to input the
island figure. The following START POINT screen is displayed.
As to the input data item
[FIGURE TYPE] is set “CONVEX”
automatically. ( When a outer wall, it is set “CONCAV”.)

The same arbitrary-figure block types as for the XY plane explained
in the previous subsection are available for the YZ plane, the XC
plane (polar coordinate interpolation plane), ZC plane and XA plane
(cylindrical surface). Their start points are specified with the
following G codes.
The data to be set for the YZ, XC, ZC and XA planes is the same as
for the XY plane except that the XY plane is changed to the YZ, XC,
ZC, or XA plane and that the direction in which the tool moves to cut
is changed to the X-axis (YZ and ZC planes) or the Z-axis (XC and
XA plane ).

Start point : G1500 (XC plane, polar coordinate interpolation plane)
Start point : G1600 (ZC plane, cylindrical surface)
Start point : G1700 (XA plane, cylindrical surface)
NOTE

When performing machining (polar coordinate
interpolation) on the XC plane, note the following:
(When bit 2 of parameter No. 27000 = 0)
The mode needs to be switched to the polar
coordinate interpolation mode beforehand.
Specifically, enter G12.1 before the machining
type.
Enter G13.1 for canceling polar coordinate
interpolation as required.
(When bit 2 of parameter No. 27000 = 1)
G12.1 and G13.1 are automatically output before
and after cycle machining, respectively.

When performing machining (cylindrical
interpolation) on the ZC and XA plane, note the
following:
(When bit 3 of parameter No. 27000 = 0)
The mode needs to be switched to the cylindrical
coordinate interpolation mode beforehand.
Specifically, enter G07.1C (cylinder radius) before
the machining type.
Enter G07.1C0 for canceling cylindrical
interpolation as required.
(When bit 3 of parameter No. 27000 = 1)
G07.1C (cylinder radius) and G07.1C0 are
automatically output before and after cycle

Fixed Form Figure Blocks for Grooving (XY Plane)
As fixed form figures for grooving, a "square", "circle", "track", and
"radial grooves" are available. When any of these pattern figures is
specified, a groove with a specified width is cut along the contour.
NOTE
Each of a "square", "circle", and "track" is a closed
figure. In actual grooving, sets of a start point and
end point are determined, and cutting from the start
point to the end point of a set is repeated.
