6.4 Circular Interpolation; G02, G03
Function and purpose
These commands serve to move the tool along an arc.
Command format
G02 (G03) X__ Y__ I__ J__ K__ F__;
G02
: Clockwise (CW)
G03
: Counterclockwise (CCW)
X, Y
: End point
I, J
: Arc center
F :
Feedrate
For the arc command, the arc end point coordinates are assigned with addresses X, Y (or Z, or
parallel axis X, Y, Z), and the arc center coordinate value is assigned with addresses I, J (or K).
Either an absolute value or incremental value can be used for the arc end point coordinate value
command, but the arc center coordinate value must always be commanded with an incremental
value from the start point.
The arc center coordinate value is commanded with an input setting unit. Caution is required for the
arc command of an axis for which the input command value differs. Command with a decimal point
to avoid confusion.
