● For circular arcs, it is necessary to specify a start point and target position, as well as a
radius (R) or center point (I, J, K). Set either a center point or radius.
● Specifying the rotational direction of circular arc
The rotational direction of a circular arc can be switched by specifying a G-code.

● Determining a coordinate specification method
The target position and center point of circular interpolation can be specified as relative
coordinates or absolute coordinates. For details on how to set relative coordinates or
absolute coordinates, refer to
coordinate specification

Circular interpolation setting examples (center point specification)
Examples of setting circular interpolation with G-code are shown below. In these examples,
target coordinates are set as absolute coordinates and center point coordinates are set as
relative coordinates.
For circular interpolation, it is necessary to specify the coordinate plane targeted for
interpolation. When using circular interpolation, specify a coordinate plane.
● Circular interpolation (XY-plane)
The following is an example of circular interpolation using an XY-plane.
[Setting example 1]
G-code setting example:
N03 G17
N04 G02 X100 Y0 I50 J0 F100 E1 E-1
• Explanation of G-code
N03: An XY-plane is selected. (This can be omitted when there is no need to change the
plane.)
N04: Circular interpolation is performed in the XY-plane according to the following values.
Current value (X0, Y0), end point (X100, Y0)
Center point (X50, Y0)
Velocity 100
Acceleration 1 [u/sec
