Example—Program Arc with Endpoint and Radius
The second method of programming a G02 or G03 block is to define the arc's endpoint
and radius. There are two possible arcs when you program X, Z, and R. The sign of the R
radius value determines whether you want the arc that spans less than 180° (by
programming R as a positive value), or the arc that spans more than 180° (by
programming R as a negative value).
N2 G90 G07 G02 X__ Z__ R+__ (G90 = Absolute; G07 = Radius; G02 = CW)
N2 G90 G07 G03 X__ Z__ R-__ (G90 = Absolute; G07 = Radius; G03 = CCW)
N7 G90 G08 G02 X__ Z__ R+__ (G90 = Absolute; G08 = Diameter; G02 = CW)
N7 G90 G08 G03 X__ Z__ R-__ (G90 = Absolute; G08 = Diameter; G03 = CCW)
N2 G91 G07 G02 X__ Z__ R+__ (G91 = Incremental; G07 = Radius G02 = CW)
N2 G91 G07 G03 X__ Z__ R-__ (G91 = Incremental; G07 = Radius; G03 = CCW)
N7 G91 G08 G02 X__ Z__ R+__ (G91 = Incremental; G08 = Diameter G02 = CW)
N7 G91 G08 G03 X__ Z__ R-__ (G91 = Incremental; G08 = Diameter; G03 = CCW)
