FineAdjust Control Chart
What does this sample chart tell us? A process shift
occurred between measurement 12 and 13. This type
of shift could occur due to a change in wire, a change in
terminal lots, a jam in the machine that damaged the
tooling, a change in operators, or an adjustment to the
insulation crimp. Since the measurements are still
within specification, would you stop production to adjust
crimp height?
A shift in the process due to a change in material may
arrant a crimp height adjustment. A shift after a jam
would not indicate an adjustment, but a close evaluation
of the tooling. A shift in the process between operators
would not indicate an adjustment, but an evaluation of
measurement capability.
The idea of the control chart is to identify what caused
the shift to justify if an adjustment to the process is
warranted.
The FineAdjust Applicator is extremely easy to adjust. It
is just as important to chart and document process
control with the FineAdjust applicator.
If the process shift is due to a jam or a change in
operators, more evaluation may be necessary than an
adjustment.
Many crimping processes have been producing product
within specification for decades. Today, with statistical
process control, the philosophy of quality is being within
specification is being replaced by being on target with
continuous reduction in variability. Control charting is a
tool that truly allows a company to understand their
process.
ATTENTION
Reference must always be made to product application /
crimp specification to determine crimp parameters.
