When the G18 (Z-X plane) command is executed
The G43.4 command is executed after moving the A- and C-axes, and
circular interpolation is performed using the G18 (Z-X plane)
command without moving any rotary axis. → This case corresponds
to <2> and allows circular interpolation.

After the G43.4 command, circular interpolation is performed using
the G18 command (Z-X plane) by moving any of the rotary axes. →

- Tool center point control command
During tool center point control, the command specifies the location
of each block end point as seen from the programming coordinate
system.
The program specifies the tool center point.
As for the rotary axis, the command specifies the coordinate values of
each block end point in the case of type 1 or the tool direction at each
block end point in the case of type 2.
The feedrate is specified by the tangential speed relative to the
workpiece (the tool's relative speed as opposed to the workpiece),
which is represented by F.
- Commands that can be specified during tool center point control
The commands that can be specified during tool center point control
are linear interpolation (G01), positioning (G00), circular
interpolation (G02, G03), and helical interpolation (G02, G03).
When linear interpolation (G01) is specified during tool center point
control, speed control is exerted so that the tool center point moves at
the specified speed.
The circular interpolation command (G02, G03) controls the
tangential speed of the arc path along which the tool center point
moves.
The helical interpolation command (G02, G03) controls the tangential
speed of the arc path along which the tool center point moves or a
synthetic speed including that of the helical axis. (This is dependent
on the setting of parameter HTG (No.1403#5).)
As the actual speed, the speed at the control point is shown.
