If you program H=2 or H=3, you can machine linear slots with a
circular base.
Define the circle center with:
H = 2: with I and K
H = 3: 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.
