3.12.1 Adjusting the feed rate
Do not adjust the feed rate while the machine is rotating, as rotating
machinery can cause serious injuries. Stop the machine completely before
adjusting the feed rate. Follow Section 3.12.2 on page 50 to conduct feed
actuation measurement.
Each rotation of the feed rate adjustment knob (see Figure 3-35) increases the feed rate
approximately 0.006" (0.15 mm). Table 3-2 provides a reference to quickly set the
approximate feed rate.
The values in Table 3-2 are
approximate. If a specific feed
per revolution is required, place
a dial indicator on the arm and
measure the feed amount while
the machine is manually rotated
one revolution, then adjust as
necessary.
