SPC analysis
is largely affected by measurement system error. Gaging instruments,
inspection techniques and fixturing all make up a measuring system. Any
of these components can introduce variation in the measuring system.
This variation in the measuring system is then reflected as part of
total process variation in the SPC analysis and negatively affects key
quality statistics like Cpk, Ppk, Ppm etc. DataLyzer® Spectrum Gage
Management helps to quantify this measurement system variation and
provides tools for reducing it.
Contents Gage Management
DataLyzer® Spectrum Gage Management will operate alone or it
will link to the DataLyzer® Spectrum SPC module. When
linked, the Gage Management module shares the Spectrum
database offering access to common setup information like
characteristic specifications along with statistical results
like Ppk/Cpk and "Gage R&R % of tolerance" so improvements
to gaging systems can be evaluated and the improvement in
overall process performance can be measured.
The 3 components of the Gage Management system are:
Gage Calibration
Records whether results from a given measuring system
are true to a standard and determines whether existing
bias is within an acceptable range. The Gage Management
software further maintains a history of these
calibration analyses for each measurement system.
Gage and Supplier information
Gage location, Gage supplier, supplier information like
shipping address, costs, service-records etc.. These
records are maintained to allow quick reference for
instrument service or replacement.
Gage Repeatability and Reproducibility studies
The system allows fast and convenient study creation
with a format, which makes the studies easy to perform.
Study results can be reviewed singly and historically.
The system further allows comparison of alternative gage
systems for the given process to minimize overall
process variation or evaluate cost vs. performance
trade-offs.
Gage Calibration
Internal and external calibration are supported
Calibration Study history, due dates and
scheduling for calibration studies, is supported
Calibration procedure can be user defined and
applied to all desired gages.
Calibration is often the largest ongoing cost of a
quality assurance department, so an effective system
will help you to reduce these costs.
Gage Repeatability & Reproducibility
Even if a measurement system can measure accurately
without bias, how consistently can it measure
production parts?
When used by one individual at different times
When used by more than one individual over time
The system
allows for standard Gage R&R studies and ANOVA studies
Gage and Supplier Information
Gage information includes location, status,
required supplies, gage type, supplier
information, calibration and GRR intervals etc.
Supplier information like address, contacts,
order information etc.
Features
Gage R&R features list
Study history, due dates and scheduling for Gage R & R
studies is supported by reports and other means
designating which gages need to be re-studied during any
given week or month.
