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 by rotating the C-axis
(table 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 IR B10. C20. ;
:
IP: Coordinates of the end point
IR: 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 IR C20. ;
:
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.
Example)
:
G43.4 H1 ;
G18 G02
IP IR C20. ;
:
After the G43.4 command, the Z-X plane is selected using the G18
command and circular interpolation is performed after rotating the C-axis.
→ Alarm (violation of <2>)
The same is also true when the G19 command is used.
Example)
:
G43.4 H1 ;
G01 C10.
G18 G02
