4.7 Cylindrical interpolation (G07.1)
This interpolation feature allows the machining to be accomplished by the c ombina-
tion of tool movements and rotation of a w orkpiece in the virtual orthogonal coordi-
nate system. Machining is possible on the circumference of cylindrical workpiece
by using the commands in an orthogonal coordinate system. To use this function,
an additional axis of rotation is necessary in addition to the normal s ervo axes (X,
Y, and Z axes).
Programming format
The cylindrical interpolation mode is turned ON and OFF by the G c odes indicated
below.
Table 4-6 G codes used for cylindrical interpolation
G code
Function Group
G07.1 Cylindrical interpolation mode 16
Format
G07.1 A (B, C) r ;
Starts the cylindrical interpolation mode (enables cylindrical interpolation).
G07.1 A (B, C) 0 ;
The cylindrical interpolation mode is cancelled.
A, B, C: An address for the rotation axis
r: The radius of the cylinder
Specify the G07.1 command in a block without other commands.
The G07.1 command is modal and once the G07.1 command is specified, the cy-
lindrical interpolation mode remains ON until the G07.1 A (B, C ) command is speci-
fied. The NC is in the cylindrical interpolation OFF mode when the power is turned
ON or when the NC is reset.
Note
S G07.1 is based on the Siemens option TRACYL. The relevant machine data
need to be set accordingly.
S For details refer to the manual “Extended Functions”, chapter M1, 2.2 ”TRA-
CYL”.
