2.8.4 CIRCULAR INTERPOLATION (G 02, G 03)
G02(G03) X( U)... Z(W) ... 1.. . K.. . F(E) ...;
A tool is moved on the circular arc whose cen-
ter is away from the present position by (I, K) .
The end point of the arc is (X, Z) in the coor-
dinate system set by G 50 or away from the
present position by (U, W)
A tool moves along a
circular arc at the tra-
verse rate specified by the F or E code.
The meanings of G02, G03 and each address
are shown below .
