    That was a code I copied off this thread of discussion.I see there is no height offset callup.here is how I would have written it.I am assuming those generic motions are what your looking for.this goes to tool centerline.

    G17 G40 g80
    T3 mo6
    G0 g90 g54 x8.0 y-3.25 s1550 m03
    G43 h03 z1.0
    Z.1
    G01 z-1.875 f25.0
    X-8.0 f7.0
    G19
    G02 y3.25 j3.25 k-2.9375
    G01 x8.0
    G03 y-3.25 j-3.25 k-2.9375
    G01 x7.87
    G0 z10.

    METALCARPENTER IS CORRECT :
    Use g19 to arc in yz axis.use ijk when programming radius is my suggestion not R...trust me.k is center of arc in
    Z axis, j is center of arc in y axis.
