Example 3: Multi-face machining
352
In this example, paraxial and inclined
workpiece surfaces are to be machined in a
clamping.
Condition:
The tool must be aligned perpendicular to
the inclined surface in the rotated Z
direction.

In this example, identical shapes are
machined in two workpiece surfaces
perpendicular to one another via
subroutines. In the new coordinate system
on the right-hand workpiece surface, infeed
direction, working plane and the zero point
have been set up as on the top surface.
Therefore, the conditions required for the
subroutine execution still apply: working
plane G17, coordinate plane X/Y, infeed
direction Z.
