G03 Command (Counterclockwise Arc)

G03 cuts a circular arc counterclockwise. It works exactly like G02 but in the opposite rotation, using the same center-offset (I, J) or radius (R) form.

Format

G03 X__ Y__ I__ J__ F__ (center offset)
G03 X__ Y__ R__ F__ (radius)

How it works

  • Direction is judged looking down at the active plane.
  • I and J locate the arc center relative to the start point; R sets the radius directly.
  • Pick G02 or G03 by which way the arc curves around its center.

Example

G03 X0.0 Y1.0 R0.5 F10.0
