Circular / helical interpolation (G02, G03) and plane specification (G17, G18,
G19)
■
Setting rules for circular interpolation
The following rules apply when G-code is used to set circular interpolation for the GM1
controller
.
● Specifying the coordinate plane for circular interpolation
For circular interpolation, it is necessary to determine the plane targeted for interpolation. If
no plane is specified, the XY-plane will be set by default.
The coordinate plane can be switched according to the G-code specification.
G-code Function
G17 Circular interpolation in the XY-plane
G18 Circular interpolation in the XZ-plane
G19 Circular interpolation in the YZ-plane
● Settings for axes untargeted for interpolation
For axes untargeted for interpolation (Z-axis in the XY
-plane), do not enter parameters (for
coordinates).
Note that if axes untargeted for circular interpolation (Z-axis in the above example) are
specified, "helical interpolation" will be set. For details on helical interpolation, refer to
"Helical interpolation setting examples (operation settings)".
● Parameters set for circular interpolation
The following table shows parameters that must be set for circular interpolation.
Parameter name Input value
Target coordinates
X-axis X xxx (xxx: Target coordinate)
Y-axis Y xxx (xxx: Target coordinate)
Z-axis Z xxx (xxx: Target coordinate)
