Chapter 2: Performance
QGAGE functionality it is divided into three stages as follows:
This stage consists of entering all the support information, such as the
properties of patterns, tools, and instruments.
The measurement system covers instruments, operators, and measurement
methods. It is essential to make a proper analysis of the measurement system
before taking any corrective action. Many times when problems occur in the
measurement system, it sends the instrument to calibrate, but there are times
when the instrument is not causing the problem. Maybe the operators or the
method used in the measurement. R&R, bias, linearity and stability studies
allow analyzing the measurement system and help to find the improvement actions.
When a measurement system has a high variation, actions must be taken to
reduce it because the measurements become unreliable. Either to calibrate the
instrument, train operators, to unify and document the measurement methods, and
establish good measurement practices are everyday actions taken to improve the
quality of the measurements. It is essential to pay attention to the resulting
graphic from the studies to correctly decide what actions to take.
Chapter 3: Utilities
This chapter shows how to record roles and users, and also how to
configure the system. To access the utilities options, click the
Upon starting QGAGE, the Reminder window with

Roles allow you to group users according to what they
do in the system. You can create as many roles as necessary. However, it is
very useful to properly analyze the roles which are needed according to the
permissions which you are going to assign, since a user can only have one
specific role. We recommend that you draft up a list of the groups and users
that are going to use the system, in order to facilitate management.

Acceptance tab
Defines the
R&R percentages to define whether the measurement system is considered
Acceptable, Under Review or Unacceptable. As well as the criteria to consider a
compliant calibration. By default, the criteria proposed in the Measurement
System Analysis manual, published by General Motor, Ford and Chrysler, are
presented.
The criteria to
know if the variability of a measurement system is satisfactory depends on the
variability percentage of the manufacturing/production process or the tolerance
of the part that is consumed by the measurement system variation. The
Final
acceptance criteria for specific measurement systems depend on the environment
and purpose of the measurement system and should be agreed with the customer.
For measurement
systems whose purpose is to analyze a process, an empirical and general rule
for the acceptance of a measurement system is as follows:
-
% R & R
<10% - generally considered an acceptable measurement system.
-
% R & R
between 10 and 30% - may be acceptable or not, based on the importance of the application,
cost of the measuring device, repair costs, etc.
-
% R & R>
30% - considered as not acceptable, efforts should be made to improve the
measurement system.
In addition,
the number of different categories (ndc), times in which the variation of the
process can be divided by the variation of the measurement system must be greater
than or equal to 5. In the event that in a given study this number is less than
5 will be considered an invalid study so it must be repeated.
Alerts tab
In this tab the
days of anticipation with which the event reminder, calibrations, R&R studies
and pattern expiration are set are configured.
-
Days in advance
for event alerts: Determines the number of days in advance with which a pending

pending calibration appears in the reminder of the responsible user. This
allows the person responsible for it to be notified before the date of the next
calibration of the instrument arrives.
-
Days in advance
for notices of R&R studies: Determines the number of days in advance with
which the pending R&R study appears in the reminder of the responsible
user. This allows the person responsible for it to be notified before the date
of the next R&R study of the instrument arrives.
-
Days in advance
for employer notices: Determines the number of days in advance with which the
employer's expiration notice appears in the reminder of the responsible user.
This allows the employer to be notified before the employer's expiration date

Analytical method tab
The analytical method uses the concept of Gage Performance Curve to
evaluate the repeatability and the gage bias. This
analysis can be used in gage of one limit and/or two limits. For a double limit gage, is only needed to examine a limit with the
assumption of linearity and error uniformity.
Generally, the analytical method consists of obtaining the reference
values for a group of selected parts. These
parts are evaluated a number of times (m), with the total number of accepts
(a), for each part being recorded. From the results,
repeatability and bias can be assessed.
The first stage of the attribute study is the part selection. It is
essential that reference value be known for each part used in the study. For
practical reasons, 8 samples of reference values equidistant are selected. The maximum and minimum values should represent the process variation.
Gage should be applied in the eight parts m=20 times and record the
number of acceptances. The smallest parts must
have the value a=0; the largest part, a=20; and the six others parts, 1≤ a
≤19. If these criteria are not satisfied, more parts with known reference
values, (X), must be run through the gage until the above conditions are met,
if, for the smallest value a≠0, then smaller and smaller parts are taken and
evaluated until a=0. If the largest value a≠20 then larger and larger parts are
taken until a=20.if six ot he parts do not have 1≤ a ≤19, additional parts can
be taken at selected points throughout the range. The first interval at the a=0
end starts from the largest measurement where a=0 and a=20 ends and worked
toward the middle of the part range. If necessary, the procedure can be
repeated until the criteria are met.

-
Bias: Represents the shifting that has the gage regarding its specification. In some cases this bias or shift is not important. When the bias is important, a legend in red indicating "significant
bias" is displayed in the report. In
this case the value of bias must be taken into account to calibrate the gage. Otherwise, it must not because it is not statistically significant.
-
R&R Gage: Gage repeatability.

Risk Analysis Method tab
In some attributes situations is not feasible to get sufficient parts
with variable reference values. In such cases, the
risks of making the wrong or inconsistent decisions can be evaluated by using:
-
Hypothesis Test Analyses
-
Signal Detection Theory
Since these methods do not quantify the measurement system variability, they
should be used under with the consent of customer. Selection
and use of such techniques should be based on good statistical practices, an
understanding of the potential sources of variation wich can affect the product
and measurement processes, and the effect of an incorrect decision on the
remaining processes and the final customer.
In this method three operators are used, and each operator takes three
decisions on each part. A Pass decision is designated with a one (1) and a Does not pass decision
with a zero (0).
The Value column contains the numerical reference value. This column can be ignored in case there is not data.

The Kappa table between operators shows the reach of agreement between
the evaluations of the operators. A value of 1 indicates
the agreement is perfect. A value of 0 indicates
the agreement is not better than a mere chance.
A general empirical rule is that the values of kappa greater than 0.75
indicate a good to excellent agreement (with a maximum of kappa = 1). Values lower than 0.4 indicates a poor agreement.
Kappa does not take into account the size of the disagreement between
the operators, only if they agree or not. This
analysis is necessary to determine if there are differences between operators
but does not tell us how good the measurement system classifies good from bad
parts.
For this analysis should be observed the last line of
the table where the values of Kappa represents the comparison between the
operator and the reference value.
The Effectiveness and Probability Summary table shows the
percentages of effectiveness, error and false alarm for each operator. The last column Pr (PM / DM) indicates the probability that the part
that the operator indicates as bad, is really bad. This
is a measure of the effectiveness.

The statistics properties most commonly used to characterize the data
quality are the bias and the variance. Bias refers to the
location of the data in relation to the reference value (master) and is
calculated as the difference between the real value (reference value) and the
observed average of the measurements. Bias is the measure of
the systematic error of the measurement system. It
is the total error contribution integrated by the combined effects of all
variation sources, known or not.
In this option is carried tout he control of all bias studies

QGAGE
calculates each individual measurement bias in respect to the reference value
and find, by linear regression, the straight line of best fit (reference value
against individual bias).
Besides to the linearity and linearity % values it is very important to
focus on the goodness of fit. The goodness of fit is
always a value between 0 and 1 that represents how well the straight line
approximates the points cloud. If this value is close
to 1 then the regression line is near the points cloud, so it can be said that
the regression equation represents quite reliable the points of the graph. If the value of the goodness of fit is far from 1 then the regression
line is not a good approximation of the measured values. In the latter case the linearity and linearity % will not shed reliable
results, so these values should not be recorded. In
such cases the study should be repeated seeking greater values of goodness of
fit.
To determine if the instrument presents problems of linearity two
hypothesis tests are performed. The first seek if the
slope of the regression line is zero. If this hypothesis is
rejected it means that the inclination of the line is considerable, which
implies that the biases for each reference value are different. In this case it is concluded that "The measurement system does
not present the same bias for all reference values."
If the hypothesis is not rejected the second hypothesis test is
performed, which consist of try if the independent term is enough close to
zero. If this second hypothesis test is rejected it means some biases are
statistically very large. In this case, it is
concluded that "The measurement system has an unacceptable linearity
".

Stability is a very important property that must have measurement
systems.
If the measurement system does not have a good
stability, the results of R&R studies are not durable, i.e. only apply to a
short period of time.
The stability is not obtained from a number or measured parameter. The statistical stability is determined through the use of control
charts.
Control charts also provide a separation mean of the variation due to
the causes that affect the measurement results (common causes of variation) of
the variation that result from specifics variations (special causes of
variation). The methods of control charts can be found in books of
processes statistical control and quality. It
is important to notice that when control charts are used one must
not only look at the points that fall outside the control limits but also
signals of special causes such as trends and adherence to the center line. In publications on process statistical control, it can be found guides
to detect these signals. The presence of these
signals and one point or points outside the control limits prove unstable or
uncontrolled conditions.
A method of studying stability of a Measurement System consists of
plotting the mean and a pattern range or sample or pattern readings regularly. From such analysis can be determined for example that a signal out of
control is a sign that the measurement system requires calibration. A calibration without a signal out of control is likely to increase the
variation of readings of the Measurement System.
It is not necessary to calculate a stability number of the measurement
system.
The indexes are commonly used as a measure of
improvement but with a control chart, the improving of the system can be seen
in the diagram. A way of improvement may be the elimination of special
causes of the process resulting in a stable process measurement. QGage has the option to perform a graphic Stability analysis through
graphical means and ranges.
In this option the calibrations performed to the measurements instruments
are controlled.

One of the main advantages of QTRAINING is the
customizing of reports. All QTRAINING reports are issued in MS Excel 2007
format. The templates are editable so that the reports are issued in the
required format. Report templates are found in the folder where the application
was installed.
To modify a report template, open the file with MS
Excel 2007 (2010 or 2013). All templates contain a Design sheet that defines where the information extracted from the
database is written. The database consists of tables containing records, and
each record consists of fields containing values that are shown in the
reports. By editing this template, the results of the reports are modified.
When issuing a report, QTRAINING reads the Design
sheet to fill the remaining sheets with the information from the database.
There are two types of reports:
1.
From a list of records.
2.
From a record combined with a list
of records from a related table.
This type of report consists of a list of records in a
table with statements. The Design
