That depends on whether you are talking about a mill or lathe.
On the lathe, you need the spindle encoder.
On the mill, for larger holes (about 3/8" and over) you can
use a thread mill, which somewhat resembles a tap but with
the rows of teeth all in a line, instead of a helix. Because these
units are expensive, and can be used for only one thread pitch,
I got a 1/4" single-row thread mill, which can do a wide range
of threads. It is really nice for cutting odd diameter threads, such
as camera lens threads, or anything much over 1/2", due to the
cost and torque required for the big taps.
