OPERATION
4. With the end mill continuing
to cut, turn the rotary table
handwheel clockwise 23 full
turns (92°), using care not to
pass the handwheel scale 0°
mark on the last turn.
5. Raise the end mill from the
workpiece, then rotate the
handwheel clockwise 45 full
turns (180°), making sure not
to pass the 0° mark. This will
bring the cutter to the starting
point of the second slot.
Note: Rotating the rotary table in
only one direction throughout
the operation will remove any
error from backlash.
6. Make a 0.083" deep hole, then
with the end mill continuing
to cut, turn the rotary table
handwheel clockwise 23 full
turns to begin the second 92°
slot.
7. Raise the end mill, rotate the
rotary table clockwise back to
the 0° mark on the rotational
scale, then take an additional
0.083" deep cut.
8. Repeat Steps 4–7, increasing
the depth of cut by 0.083" each
time, until the final depth of cut
is reached for each slot.
