1.4.5 Arbitrary Figure Blocks for Contouring (YZ Plane, XC Plane,
ZC Plane, XA Plane)
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 planes and XA plane is the
same as for the XY plane except that the XY plane is changed to the
YZ, XC, ZC 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 : G1300 (YZ 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
1 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.
2 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
machining, respectively.
3 The following parameter setting is necessary to
execute XA plane cycle.
• No.27003#2=1, 27003#1=0 and 27003#0=0
