Product Overview

SigmundStacks is a Tolerance 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 and hard tooling procurement. SigmundStacks prevents costly tweaking delays at ramp-up as well as long-term variation problems.

• Tried and tested in real world manufacturing industry.

SigmundStacks enables engineers to quickly and efficiently evaluate the one-dimensional (linear stacks) effects of component tolerances and assembly process variations on the quality of manufactured products.

Features

• Software tool for Design for Six Sigma initiative.

• Quickly predict % Out of spec, DPPM, Sigma, Cpk, Mean Shift, etc. to evaluate product designs before launch.

• Five analysis types including: Worst Case, RSS (Root Sum Squares), 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).

• Provides Tolerance Optimizer (Patent Pending).

• Auto-Update – change the tolerance once, and all variation analysis studies get automatically updated.

• Graphical identification and summary feedback of all red quality issues in existing design.

• What-if analysis Report to quickly evaluate multiple design concepts to

• reduce costly and time-consuming extended prototyping.

Wide range of statistical distributions.

• Single source documentation for all tolerance studies and build objectives.

• Automatic Statistical Report generation including Sensitivity and SPC Reports.

• Easy to use / quick to learn – Eliminates need for an expert user.

• Perform variation analysis studies in minutes.

• Low cost floating license pricing structure.

• Wide range of reporting formats.

• Single window integration.

• GD&T syntax checker.

Benefits

SigmundStacks includes five methods of analysis along with the ability to create studies that can be driven either by build objective or by individual piece part tolerances. SigmundStacks even includes a powerful 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. Some of the key benefits associated with SigmundStacks are:

• Greatly reduce modeling time and effort, and its succinct, reporting module provides all relevant information in four easy-to-interpret reports.

• 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.

• Enables companies to increase product quality, reduce production costs, and get their best-in-class products to the market sooner.

• Significant cost and time savings.

• Reduction in Product Development cycle time.

• 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.

• Root Cause Manufacturing Quality fires with built-in Sensitivity report.

• Identify and prevent defects from occurring.

• Identify and Select lower cost manufacturing processes in non-critical areas that will still meet all quality objectives with built-in Cost Savings reports.
