Need for Sigmund • Introduction – – – Better ways of approaching Product Design Variation is Inherent in Nature CAD doesn’t Manufacture Components Real, Actual Manufacturing Processes do Design for Six Sigma Initiative © Copyright Protected, Varatech Inc.

Need for Sigmund • High cost of poorly manufactured products – $ millions: Recalls, Lawsuits, Brand Destruction – Redesign, Retool, Remanufacture • Problems are identified after tools are cut, production is run, and products sold. • 83% of survey respondents in Quality Magazine say quality related defects are related to assembly build variation issues. • 30%-50% of scrap and rework caused by poor tolerance and variation management. © Copyright Protected, Varatech Inc.

Need for Sigmund Variation Analysis is very important for: • • The manufacturability of a proposed design Reducing cost and time Improving quality and preventing defects A manufacturing company’s competitiveness, marketshare, bottom-line profitability and survival. © Copyright Protected, Varatech Inc.

Statistics from Quality Magazine … 51% of respondents want to reduce costs while 42% want to achieve tighter part quality standards. … 69% of survey respondents want to invest to improve manufacturing efficiency while 59% will invest to reduce scrap and rework. 83% believe assembly variation issues are responsible for quality related defects © Copyright Protected, Varatech Inc.

Sigmund Benefits • Identify cost savings in areas where component tolerances can be relaxed. • Eliminate market entry disasters by forcing designers to specify aesthetic and functional build objectives up front rather than after problems occur. • Enterprise wide Design for Six Sigma initiative – Deductive Methodology to optimize and control Assembly Build Variation and Product Quality. © Copyright Protected, Varatech Inc.

Traditional Vs Sigmund Comparison Between Traditional Approach Vs Utilizing Sigmund Software • No need for any Manual Data Entry operations or hand calculations • Click of a Button Does – Auto loads all information from Solid. Works – Perform What-if analysis and tighten or loosen tolerances where-ever necessary – Drives and Documents all the Statistics, Sensitivity, SPC, Cost-Savings reports – And much more… • Easy to adopt for Personal – eliminating the need for specialist – Cost Savings… © Copyright Protected, Varatech Inc.

Who needs to do Variation Analysis? Variation Analysis activity needs to be performed by: • Design engineers and managers • CAE/Dimensional Control Engineers • Quality Engineers and Managers • Tooling, Fixturing Department • Manufacturing Engineers and Managers • Six Sigma Implementers © Copyright Protected, Varatech Inc.

Sigmund Highlights Sigmund Drives: • • Design Optimization Quality Program SPC Cost Savings Sigmund’s Living Models Provide: • Strategic Continuous Improvement • What-if Studies • Manufacturing Problem Resolution © Copyright Protected, Varatech Inc.

Sigmund Highlights Contd. . • Enables companies to build world class products • Predicts whether products meet their quality objectives • Identifies where problems would exist in production • Root Cause Analysis capabilities to fix problems • Saves significant cost by optimizing design/process before cutting any tools or going into production Tolerance analysis tools can influence the cost of quality through control of scrap, rework, as well as reducing warranty costs. According to Quality Magazine, April 2001, about 30% to 50% of scrap and rework is caused by poor tolerance / variation management. © Copyright Protected, Varatech Inc.
