FDB Dowel Teaching Tool
The Figure shows the FDB dimensions. The FDB provides radial
compliance and performs best when the cuts taken are not
excessively deep. The Deburring spindle must never be running
while programming a machining center or the robot. During
teaching, the compliance air must be on and supplied above a
minimum of 1.4 bar (FDB-150) or 0.35 bar
(FDB-300/-340/660/990/1040).
Two programming methods are suggested but others are possible.
In the first method, a dowel pin of suitable diameter is inserted in
place of a cutting tool (simulating the cutter shank diameter) when
teaching the robot path. For 6mm (1/8") collets, this will mean a
6mm (1/8") diameter pin of suitable length. The dowel pin should
extend sufficiently from the collet to reach the surface on the burr
where cutting is desired. The diameter of the cutter should not
exceed that of the dowel pin by more than the compliance range
of the FDB.
