Works with SolidWorks Part, Assembly, & Drawing Modes


• 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

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 assembly build variationvariation issues.

• 30%-50% of scrap and rework caused by poor tolerance and variation management.

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, market-

share, bottom-line profitability and survival.

Need for Sigmund


…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

…51% of respondents want to reduce costs while 42% want to achieve tighter part quality standards.

Statistics from Quality Magazine


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.


Traditional Vs Sigmund

• No need for any Manual Data Entry operations or hand calculations

• Click of a Button Does– Auto loads all information from SolidWorks– 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 much more…

• Easy to adopt for Personal – eliminating the need for specialist – Cost Savings…

Reading Tolerances

• Automatically reads-in all Piece-part and Assembly tolerances from SolidWorks into SigmundWorks

• Transfers all GD&T annotations and the following 4 tolerances types from SolidWorks to SigmundWorks:– Basic– Bilateral– Limit– Symmetric

• Create custom tolerances within SigmundWorks


Built-In Intelligent Loop

• Select features on SolidWorks model and then build study automatically.

Study Types

Two methodologies for creating studies

• Roll Up– Determine the effect of tolerances that have already been

defined within SolidWorks on a design goal.

• Roll Down (Design for Six Sigma)– Sigmund automatically determines and allocates tolerance

values required to meet pre-defined build objectives.


Analysis Methods

Root Sum Squared (RSS)

Modified RSS

Maintain Studies

• Maintain an electronic quality manual within SolidWorks for the entire life of the product.


Automatic Updating

• Automatically update tolerances in all stack-up studies from SolidWorks– When a Tolerance Value Changes– Design Changes– Supplier Changes– Etc..

• Update SolidWorks files with optimized results with a click of a button– Track Results– Auto Write back optimized values to SolidWorks


Tolerance Optimizer (Patent Pending)

• Ensures all Six Sigma Roll-Down Assembly Build Specifications are met

& Simultaneously

• Identifies Tolerances that can be increased and automatically increases them to their maximum value for Cost Reduction

• Optimize all tolerances with a single mouse click

Sigmund Optimizer automatically does the following at a click of a button:

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

Who needs to do Variation Analysis?


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


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%30% to 50% of scrap and rework is caused by poor tolerance / variation management.


Summary

• Significant Cost & Time Savings • Reduction in Scrap, Rework, COPQ• Robust Product Design and Quality• Efficient Product Quality Lifecycle Management• Enterprise Wide Six Sigma Initiative• Strategic Continuous Improvement• Effective Decision Making • Easy-to-Use, Quick-to-Learn…..
