Description
1305 BIT 00000000 Bit 1: Specifies whether to output the radius
for cylindrical interpolation with or
without a decimal point.
0: Without a decimal point.
1: With a decimal point.
1340 Integer 0 0: The Caxis is parallel to the X–axis.
1: The Caxis is parallel to the Y–axis.
1341 Integer 0 0: Match the number of fractional digits of
the Xaxis least input increment in MTF
No.1030.
1: Match the number of fractional digits of
the Zaxis least input increment in MTF
No.1031.

Function

Outputs a G code
for cylindrical
interpolation.
FS15: G7.1
FS16: G107
CAUTION
1 If MTF No.1340 is 0 (the Caxis is parallel to the X–axis),
G18 is output as the plane selection command at the start
of circular interpolation. In this case, a left–handed
coordinate system is used. If 1340 is 1 (the Caxis is
parallel to the Yaxis), the plane selection command is G19,
and righthanded coordinate system is used.
2 For the G1 move command at the start of cylindrical
interpolation, dummy values W0 and H0 are a output. This
means that approach takes place before the start of
cylindrical interpolation.
3 The cylinder radius specified in the cylindrical interpolation
command is output in the least input increment for the axis
specified in MTF No.1341.
4 If bit 1 of MTF No.1305 is set to 0, the cylinder radius
specified in the cylindrical interpolation command is output
without a decimal point. If bit 1 of MTF No.1305 is set to 1,
the radius is output with a decimal point. (MTF No.1305 is
also referenced for the C0 value output at the end of
cylindrical interpolation.)
