10.3 Parameters related to rotary table axes
19720 Axis number of linear axis 1 in the tool radius compensation for 5-axis machining
19721 Axis number of linear axis 2 in the tool radius compensation for 5-axis machining
19722 Axis number of linear axis 3 in the tool radius compensation for 5-axis machining
[Data type] Byte
[Valid data range] 1 ~ number of controlled axes
Set the axis numbers of the three linear axes used for the tool radius compensation
for 5-axis machining.
(The linear axes correspond to the coordinate axes in the workpiece coordinate
system.)
19723 Axis number of the rotary axis
in the tool radius compensation for 5-axis machining (first set)
19724 Axis number of the linear axis corresponding to the rotary axis
in the tool radius compensation for 5-axis machining (first set)
19725 Axis number of the rotary axis
in the tool radius compensation for 5-axis machining (second set)
19726 Axis number of the linear axis corresponding to the rotary axis
in the tool radius compensation for 5-axis machining (second set)
[Data type] Byte
[Invalid data range] 1 ~ number of controlled axes (Parameter No.19723 and No.19725 might be
negative number of controlled axis)
Set the axis numbers of the rotary axes used for the tool radius compensation for
5-axis machining, as well as the axis numbers of the linear axes corresponding to the
rotary axes. Up to two sets can be set. The orientation of the rotary axis in the first
set depends on the angle of the rotary axis in the second set. If there is only one
rotary axis, set 0 for parameter No.19725.
The axis numbers of the linear axes corresponding to the rotary axes indicate the
linear axes about which the rotary axes rotate. See the table below.
