Setting up Drill Interpolation knowledge.
There are two sample cut knowledges in the Drill Interpolation sample drawing. Each of them is designed to show a slightly different configuration to drilling. The first one will make the cuts in one pass in Z, and the second will make the cuts in multiple passes in Z.
DrillInterp1Pass
The steps necessary to make Drill Interpolation function are to select a Router-Bit from the tool list, change the cycle to Drill Interpolation and change your Status settings to the variables necessary to cut the hole.
Using these settings will produce cuts that look like this in the drawing:
If you zoom close up to the bottom of the cuts, you will see that these tool paths have a small arc lead in and lead out and move the cutter in a circle around the shape to create the hole.
Sequencing the cuts will produce code that looks similar to this:

DrillInterp2Pass
Changing the knowledge to support multiple depths per pass is a simple matter of changing the Depth Per Pass to a value that will allow the tool to cut more than once.
Cutting two more holes with this knowledge will clearly show two passes in Z on each hole.
Sequencing these cuts results in the tool leading in to the first depth, cutting the circle and then retracting to the Safety Plane, next plunging to the final depth and cutting the circle and then retracting out of the hole to the Safety Plane, and then moving over to the next hole to start the procedure again.
