This package was written to analyze the efficiency of the manufacturing process associated with the making of printer nozzle heads. The machine-inspected parameters of the printer nozzle heads were collected and fed to this software. The package calculated a large amount of statistical data based on this input and summarized the information on the screen and generated graphs and reports. This package was written in Visual C++ using the Math.h++ class libraries from Rogue Wave Software.

This software used matrices to calculate the best-fit and the least-fit of the numerical data.

It also had in-built routines to detect and remove out of bound entries from the data. A scatter diagram of the nozzle data was plotted along with the best-fit, least-fit graphs. The user was allowed to dynamically interact with the graphs changing the various input parameters. All statistical data was verified against a ëboundsí file for validity. In case a variance from the expected values was found these were brought to the attention of the user by highlighting them.
