Note: The Model G9249 ships with the
change gears in the 40T/127T/40T configu-
ration, which will cover most feed rates and
inch threading.

For Example: The operation is a shallow
finish cut on an aluminum workpiece. The
chart in Figure 52 recommends a feed rate
of 0.005–0.100 IPR (inches per revolution).
Because this is a shallow cut, we could select
a feed rate of 0.0082 IPR. To set this feed
rate, seat the left feed rate selector in the
"E" indent, and the right selector in the "1"
indent.
