100% production line testing with noise and vibration based criteria and failure mode identification.

Automated Assurance - Many products, from domestic appliances to automotive products, possess intrinsic vibration and sound characteristics that may be used as indicators of mechanical integrity. SigQC is a production line test that responds to the demand among manufacturers to automate a process for accepting or rejecting units on the assembly line based on measured noise and vibration data. SigQC provides a wide range of statistics, criteria, strategies and Pass/Fail methods.

The SigQC Pass/Fail Criteria is based on data obtained from various sources. Data sources can be measured directly using spectrum analyzers, "plug-in" data acquisition cards, digital signal processors and other types of data acquisition devices. In addition to the standard data acquisition sources, SigQC supports post-processing data sources. A post-processed data source is the result of a mathematical equation or algorithm. Post-processed algorithms are easily programmed by dragging and dropping the available post-processing options to form an equation. The result of the equation becomes available in the list of data sources in the Acceptance Test Wizard.

Database Management - The SigQC data repository is integrated with the RAIMA Velocis(TM) Data Server and optimized for speed and data integrity. In the world of production where cycle time is comparable to gold, SigQC delivers the fastest product on the market. As with any database, it is important to have a wealth of data management tools to maintain the database. On a production line where a new set of data is generated every 2 seconds, 24 hours a day, 365 days a year, it is important to have flexibility.

Although disk space is inexpensive, it is not unlimited. With SigQC you can limit the size of the database to a number of days, weeks, months or years. This, along with the available storage rules, provides you with complete control over your data.

All database files are kept in a single folder, allowing for simple archiving of the database. Archiving the database, coupled with the database depth management capabilities, provides an easy and sure-proof means of maintaining a library of all data for all parts without jeopardizing down time. No more embarrassing loss-of-data moments.

Production Line Interface

Production Line Interfaces - The SigQC interface to Programmable Logic Controllers (PLC) is designed for easy user configuration. Currently there are two methods of communicating with a PLC: through Digital I/O (contact closures) and RS232 Serial Communications.

When using RS232 Serial Communications, an input/output command set is defined using the RS232 Configuration Panel. There are special SERIAL communication steps available in the production line sequence.

When using Digital I/O, the system is configured through the Digital I/O configuration panel. Simply point and click on the input or output and define the meaning of a high or low level. I/O bits can be grouped to make up a binary value (this is useful when defining model numbers or failure modes). The Digital I/O setup is used in the production line sequence for controlling the selection of model number, start/stop acquisition, pass/fail, output of failure mode, etc.
