Tool and Fixture Design
The most important aspect of tool and xture design is
that it is safe. Please note that using tools not provided
by Dukane may result in voiding of the warranty
– consult Dukane for details.
Several aspects should be considered when tooling is
not purchased from Dukane:
tool nest should be designed such that part being
held is rmly retained in the tool so that it does
not fall out before being welded
tool should surround part being held where pos-
sible – the exterior of the tool should be a con-
tinuous cylindrical surface (i.e. avoid protruding
parts)
rotational play between tool and part should be
minimized – this will affect the angular orienta-
tion accuracy and repeatability
tool should be as light as possible to allow for
rapid deceleration and to keep machine energy
consumption to a minimum
tool should be balanced as accurately as possible
to avoid excessive machine vibration and bearing
wear
bottom xture should grip the part rmly to
maintain accurate weld orientation and prevent
undesirable vibrations during welding
