When the G17 (X-Y plane) command is executed
After the G43.4 command, the X-Y plane is selected using the G17 command and
circular interpolation is performed with rotating the C-axis (table rotation axis) and
B-axis (tool rotation axis) (including those cases where the C-axis moves before the
G43.4 command).
→ This case corresponds to <1> and allows circular interpolation.
Example)
…
(G01 C90. ;)
G43.4 H1 ;
G17 G02 IP R30.0 B10. C20. ;
…
IP: Coordinates of the end point
R: Arc radius
When the G18 (Z-X plane) or G19 (Y-Z plane) command is executed
After the G43.4 command, the Z-X plane is selected using the G18 command and
circular interpolation is performed without rotating the C-axis (including those cases
where the C-axis moves before the G43.4 command).
→ This case corresponds to <2> and allows circular interpolation.
The same is also true when the G19 command is used.
Example)
…
G43.4 H1 ;
G18 G02 IP R30. B20. ;
…
After the G43.4 command, the Z-X plane is selected using the G18 command and the
C-axis is rotated during circular interpolation .
→ Alarm (violation of <2>)
The same is also true when the G19 command is used.
