InfinityQS Real-time SPC Software: Tech Notes

Tech Notes

Tracking Multiple Frozen Food Ingredients on a Single Chart

See how InfinityQS software can be implemented in a frozen food environment. In this pizza example, ingredients are incrementally added and weights are calculated by subtracting off the weights of previous operations.

Tech Note Understanding the DPMO & DPTO Control Charts

Standard control charts for monitoring the defect rate of a process include the c-chart and the u-chart. C-charts can be used to monitor the actual “counts” of defects from a process. When the number of items within a subgroup varies, the u-charts, which tracks the actual defects per unit, can be used. But, these two charts are not ideally suited for monitoring defects occurring on parts of varying complexities.

Tech Note Viewing OLE Documents Using the ProFicient Toolbar

Viewing OLE (object linking and embedding) documents can be done using the ProFicient toolbar. Any object that can be viewed in a Windows Operating System environment can be considered an OLE object.

Tech Note Using Language Files

InfinityQS applications support full multilingual language display capabilities. The ability to switch between different languages is only a matter of selecting a language preference and the new language will be displayed on all forms and menus.

Tech Note The Kruskal-Wallis (KW) Test

The Kruskal-Wallis (KW) test is a non-parametric test used to compare three or more independent groups of data. It is used to test the null hypothesis that all populations have identical distribution functions against the alternative hypothesis that at least two of the samples differ.

Tech Note Creating Charts Using Object Linking and Embedding

Job jackets, drawing, work instructions and other documents can easily and quickly be viewed by using the built-in OLE (object linking and embedding) capability in ProFicient.

Tech Note Solving the Tight Control

There is more payback to be gained working on in-control processes with low Cpks than statistically out-of-control processes with very high Cpks. Rather than continue to remain frustrated with this classic dilemma, this tech note looks at the problem a little differently.

Tech Note How to Create an ODBC Database in Microsoft Access

This Tech Note provides instructions on creating an ODBC Database in Microsoft Access.

Tech Note Understanding the Gaging Device Format Definition

This tech note explains the Gaging Device Format Definition in ProFicient. The Format Definition section specifies how a gage is accessed and how the data is parsed into the separate fields. The format definition can contain items such as gage initialization string, whether or not fields are comma or tab separated and character positions for the data.

Tech Note Standard Deviations & Capability Indices

Variation is present in everything we do. Indeed, no two things are exactly alike. One of the most widely accepted and quoted statistics for quantifying this variability is the standard deviation. However, there are many ways of calculating standard deviation and, therefore, different ways of applying process potential and performance indices. Estimates of standard deviation can be in the form of either short-term or long-term variation. This tech note explains the difference between the two.
