SigmundStacks is a tolerance stack/variation analysis software that enables engineers to evaluate, optimize and validate assembly build quality, relative to piece part tolerance and assembly process variation early in the development phase before design solidification. SigmundStacks prevents costly tweaking delays at ramp-up as well as long-term variation problems.

FEATURES:

• Five analysis types including: Worst Case, RSS (Root Sum Square), Modified RSS, Monte Carlo Simulations, and Process Centering RSS Analysis (account for factors like mean-shifts due to tool wear).
• Predicts the quality of an assembly based upon predetermined build objectives (roll down studies), or determines the component tolerances to meet a given assembly build objective (roll up studies).
• Graphical identification and summary feedback of all build quality issues in existing/proposed design.
• What-if analysis to quickly evaluate multiple design concepts to reduce costly and time-consuming prototyping.
• Easy to use / quick to learn - Eliminates need for an expert user.

BENEFITS:

SigmundStacks enables engineers to quickly and efficiently evaluate the effects of component tolerances and assembly process variations on the quality of designed/manufactured products. SigmundStacks even includes a powerful optimization utility, which automatically optimizes all tolerances in a given model. These features accelerate an engineer’s understanding of the combined effects of component tolerances and assembly variation on a final assembly’s quality and performance.

• Easy to use menu-driven modeling capabilities reduce the user’s need to perform advanced mathematics or programming.
• Optimizes design and assembly process, adds precision where needed, and eliminates overly costly designs.
• Improve Quality and Reduce huge scrap, rework, retooling, recalls and warranty costs before they are incurred – High Return On Investment from use on just one program.
