4.2.1. Part adjustment
Form and diameter of the bar, length of part, face-off variable distance
Material shape
Round bar:
•
Outside diameter
Hexagonal / square bar:
•
Size on flat sides
•
Size on corners
During the bar feed cycle, the bar feeder tries several times (during 2 minutes) to insert the bar in
the lathe collet or chuck. The precision of the positioning is also ensured by a procedure specially
dedicated to profiled bars.
Total feeding length
The total loading length (Lt) included the work piece length (Lp) , the thickness of the top-cut tool ( C ) and
the thickness of the facing tool (not represented on this picture, depends on the part program).
Number of openings of the clamping unit per part
When the machining of a part requires several openings of the
collet (e.g. a long part, or transfer of the part to the second
spindle), some interface conflicts may occur during the feeding process.
It is important for the bar feeder to be “informed” of the number of times the collet must open for the
machining of a part.
The bar feed system only carries out the first positioning for a single part. The following positioning (if
any) must be done by the turret.
