If you program H=2 or H=3, you can machine linear slots with a
circular base. If
 H=2: Define the circle center with I and K.
 H=3: Define the circle center with J and K.
Programming:
 X, C, XK, YK, Z: Absolute, incremental or modal
 I, J, K: Absolute or incremental
 Program either X–C or XK–YK
 Program either center or radius
 For radius: Only arcs <= 180° are possible
 End point in the coordinate origin: Program XK=0 and
YK=0.
