7. END OF BAR POSITION
Description
The end of bar position determines the moment when the bar
feed enters the loading cycle.
Usually, the end of bar position is adjusted as closely as possible
behind the clamping system of the lathe (approximately 5 mm or
a 1/4" behind the chuck jaws or collet pads).
This will provide minimum bar stock remnant.
Regardless of the length of the bars, or parts, the end of bar
position is always the same.
In very special cases, a different end of bar setting needs to be
selected.
The length of the remnant may vary :
· The minimum remnant length (Min) is obtained when the
feeding pusher is just behind the clamping device while the
last part is being machined.
· The maximum remnant length (Max) is obtained when there
is not enough material for machining an additional part (Lp
- 1 mm).
Maximum remnant length = Lp - 1 mm + Min
Setting
Before handling the bar feeder, stop the lathe at the end of part cycle !
