Machining with the Y axis
The milling and drilling contours are nested in the following NC
program. A linear slot is machined on the single surface. On the same
single surface, a hole pattern with two holes is machined both to the
left and right of the slot.
At first, the turning operation is performed, and then the single surface
is milled. Following that, the linear slot is machined using the "Pocket
milling, lateral surface Y" unit. Then the slot is deburred. Further units
are used to center the hole patterns, then drill them and finally tap the
holes.
