1.7.3 Fixed Form Figure Blocks for Grooving (YZ Plane, XC Plane)
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).
Square : G1320 (YZ plane)
Circle : G1321 (YZ plane)
Track : G1322 (YZ plane)
Radial groove : G1323 (YZ plane)
Square : G1520 (XC plane, polar coordinate interpolation plane)
Circle : G1521 (XC plane, polar coordinate interpolation plane)
Track : G1522 (XC plane, polar coordinate interpolation plane)
Radial groove : G1523 (XC plane, polar coordinate interpolation plane)
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.
