DCS-Datum Flow Chain (DCS-DFC)

A "Datum Flow Chain" is a graphical diagram that defines the relationships between assembled parts, assembly fixtures, tooling and equipment. DCS-DFC software provides analysis along any selected linear path of a Cartesian coordinate system. With an intuitive graphical user interface employing "point & click" operations, DCS-DFC is a premier tool for facilitating assembly-first product design where part tolerances can be maximized for cost reduction.

DCS-DFC easy-to-read dialog boxes are used to identify part datums, tolerances, locating features, for components and assembly specifications. DCS-DFC uses this criteria to predict the variation for each defined measurement. Unlike typical 1-D analysis solutions, DCS-DFC allows users to link feature tolerances to more than one specification and analyze all of the assembly requirements within a single model. A multitude of statistical calculations; such as standard deviation, percent out of specification, Pp / Ppk, and confidence intervals, are calculated and displayed in a variety of graphic output formats for generating reports.
