EXAMPLE G13 multiple-pass using I, K, and Q:
This example will complete a three-inch diameter hole, one inch deep, with a cutter overlap of .100 thousandths
of an inch.

EXAMPLE G13 Multiple-pass using I, K, Q, L, and G91:
This program uses G91 and an L count of 4. This cycle will execute a total of four times. The Z depth incre-
ment is .500. This is multiplied by the L count, making the total depth of this hole 2.000.
The G91 and L count can also be used in G13 "I only" line.
Note: If the geometry column of the offsets display page has a value inserted within,
the circular pocket milling cycle will automatically read the data, regardless of
the D01 being present or not. The only effective way to cancel the cutter
compensation for the pocket milling is to insert a D00 in the program line. This
will bypass the value in the geometry column.
