Example of multi-side machining
In this example, identical shapes on two perpendicular workpiece surfaces are machined by
using subprograms. The setup of the infeed direction, working plane and zero point in the
new coordinate system on the right-hand workpiece surface matches that of the top surface.
The conditions required for subprogram execution apply as before: Working plane G17,
coordinate plane X/Y, infeed direction Z.
