3.
Engage the number of trips required for the surface
finish desired. Refer to Table 4 earlier in this chapter.
4.
Refer to Table 5 for the required axial feed rate for the
number of trips you are using. This is the distance you
will need to
retract
the
EXAMPLE
:
To cut a 30° bevel with 6 trips
engaged, you must withdraw
the cutting tool .018” each
time the cutting tool com-
pletes a revolution (turning
the feed handle counter-
clockwise). Use the cali-
brated feed label on the feed
handle assembly.
5.
With the FF 206 set up as described earlier in this
chapter, turn the feed handle clockwise until the tool
bit just touches the pipe face.
6.
Turn the starwheel on the radial slide counter-clock-
wise until the tool bit is past the O.D. of the pipe face.
7.
Turn the feed handle clockwise to advance the tool bit
to the desired cutting depth. If you are cutting multiple
passes, advance it to the position of the first pass.
8.
Start the machine and allow the radial slide to advance
until the tool contacts the O.D. of the pipe.
9.
When the tool touches the O.D., start turning the feed
handle counter-clockwise by the required feed rate
from Table 5. Refer to the calibrated feed label.
10.
Operate the machine until the pass is complete and the
tool is no longer engaged with the pipe surface. Turn
off the machine.
11.
If you need to cut another pass, reset the tool position
to the required location on the O.D. of the pipe.
Repeat the required number of passes.
