AT SIGMA
SPC SPECS
- Real Time automated SPC using
virtually any database
- ISO-9000 support through
on-line process documentation (HTML, Windows Helpfiles,
Adobe Acrobat )
- Easy to learn, flexible,
quick, with powerful results
- Simultaneous multiple
variable analysis in overlapped MDI windows for quick
viewing & troubleshooting
- Accesses data and stores it
in any database allowing infinite data points and
sophisticated fast queries and sorts in charts. Databases
like Paradox, Oracle and others, as well as ODBC sources,
make for enterprise wide data sharing and security
- Fully customizable closed
loop reaction, dispositioning and trigger events
- Normal and non-normal
(Johnson) analysis gives actual and estimated capability
and yield
- Fully network secure and
sharable using existing data base infrastructure
- Data entry can be automatic
with AT-Sigma Data Pipe (RS232 Serial), or AT-Sigma
W-Import (text files), built in grid or any entry
building application (Visual Basic, C, Delphi, etc.)
- All analysis is performed on
database tables
- Virtually all database types
supported (Paradox, dBase, MS Access, ODBC, SQL Tables)
- Supports client/server SQL
systems (ORACLE, SYBASE, Informix, Interbase and other
SQL servers)
- Full record locking and
contention control for local databases or networked
shared environments
- Configuration files and data
can be located on a network for easy enterprise wide
maintenance
- Most configuration is stored
in industry standard formats that allow automated updates
of specs
- Charts can be
produced by the result of a query. This allows a chart
sorted by Operator, Date/Time, Machine or any other
descriptive information. Full AND/OR conditionals based
on ANSI-92 SQL even for local Tables
- Query By Example simplifies
setting up queries for control charts in the Product
Filter. The result of the query can be viewed at that
time to verify the query and the selected data.
- AT-Sigma
Data Pipe
- serial (RS232) data
- Automatic data acquisition is
supported for virtually all serial gages and devices
using our DATA PIPE's universal serial driver (optional)
- AT-Sigma Data Pipe can stream
serial data directly to a database and trigger auto SPC
Analysis
- Supports TIR (total indicator
reading) function. This allows continuous monitoring of
the gage and calculates Minimum and Maximum values, which
are both available for storage.
- AT-Sigma
W-Import -
text file collector
- Automatically detects and
imports text (ASCII) files in comma separated value
format (CSV) or user defined format
- Automatically notifies
AT-Sigma SPC, or other DDE aware program that processing
is needed
- Full parsing, Date/Time
stamping, fixed/variable length, delimited or not, and
many other options to handle all text files
- Sophisticated file management
handles contention and auto archives data to mainframes
or other locations based on number of records or age of
data
- Built-in spreadsheet type
entry supports keyboard or barcode
- Custom entry through any form
design package: Visual Basic, Paradox for Windows, C++ or
similar package
- Communicates through Windows
DDE for universal compatibility and connectivity
- Auto-entry through AT-Sigma
Data Pipe and AT-Sigma W-Import with time stamp, date
stamp, parsing of input lines
- Manual
Data Entry Module
- Calculated fields on data
entry screens
- Can collect up to 35
variables via scrolling entry form. Database thresholds
are unlimited.
- Includes support for pick
list fields where an operator is presented with a set of
choices for a field and the field is filled with the
selection. This reduces errors in entry. (e.g Scratch and
scratched are not grouped together)
- Allows a ‘GroupID’
automatic incrementing field. This inserts a unique
number for each sample sub-group so the grouping in the
database can be easily seen. Especially good for variable
sample sizes or when data is added or removed at later
dates.
- Ability to collect by part or
by characteristic. That is collecting all measurements
for each part or measuring the same data on each part
then going to the next dimension.
- Redo function that allows an
operator to start the group over from scratch
- X-Bar and Range
- X-Bar and Sigma
- Individuals and Moving Range
- np (number of defectives)
- p (percent of defectives)
- c (number of defects)
- u (percent of defects)
- Most of the above control
charts can be processed using the following options:
- Standard
- Nominal
- Short-Run
- Group charts
- Median chart
- Moving average, moving
individual control chart types
- Individual data points
plotted on any control chart
- Spec limits plotted on any
control chart
- Can fix control chart
centerline to target value
- User set control limits or
auto-calculated
- User scale or auto-scale
- Charts include links to
details, called Tags, that display process changes,
causes, actions and comments
- Charts change color to depict
current status (red, yellow)
- Fully customizable colors,
size and symbols on all charts
- View charts and data on the
same screen while collecting data
- Context switching based on
incoming data allows unlimited control chart sets
- Ability to ignore subgroups
then re-calculate the control limits.
- Sample size can be up to 400
for fixed and variable sample size charts.
- Support for Group Charting
- Mean, Standard Deviation,
Skewness, Kurtosis, 99.73% points
- Normality testing - user can
select sample ranges that determine the normality test to
use. Select from Shapiro-Wilk, Anderson-Darling, and
Skewness-Kurtosis
- Non-normal approximations are
used
- Normal, LogNormal, non-normal
distributions

non-normal information

include Cause, Action, Comment and other details in the
automatic message.

for easy viewing
- Pareto chart of causes or
actions
- User defined online reaction
plan can contain drawings, photos, video, voice and
hypertext jumps to guide operator through proper
measurement and corrective steps. HTML, Windows HLP file,
Adobe Acrobat or other document viewers supported
- Operator Help files can now
be in HTML. We include our own internal viewer to limit
ability to jump to the links in the file. You can also
use an external browser of your choice. This eases
maintenance since many HTML editors are available
including all current versions of Word processors (use
‘Save As…HTML').
- These tests determine when an
alert condition occurs. Each variable has full control of
the sensitivity of the tests applied to it
- Standard Western Electric
tests (8)
- User customizable rules tests

- Turn any test on/off for any
variable
- Disposition of Sub-group Test
based on % out of spec or sample average vs. limits.
