7.9.1.1 Global adjustment tool principle
This tool is based on a comparison with fixed reference (a good lead/joint). Tolerances
are constructed in relation to this reference. This reference is defined on several good
leads. For this, a reference profile is done on a good lead, and tolerances are constructed
in relation to this reference. So they are fixed for all components of a same models. Each
profile out of tolerances is considered as bad.
7.9.1.2 Lead to Lead tool principle
This tool allows to adapt to the variations
of aspect related to a change in the pro-
duction (aspect of the welding, aspect of
the component leads…). It is not sensi-
tive to difference between components.
For the lead to lead tool, the comparison
is with the average of all profiles of the
components.
This tool is based on a comparison with
adaptive reference.
Tolerances are auto-
matically adjusted for
each component of a
same model. Toleranc-
es are adaptive.
By using these 2 methods simultaneously, bad leads can be detected on joint by taking
into account of variation of production.
Tolerance must
be large to in-
clude all possible
variations of pro-
duction (lead and
welding aspect,
lead size ...).
Tolerances
could be tight
to detect more
defects.
