          Sigmetrix To Sponsor COExperience 2023 in Miami, FL

          2 Minute Read

          Attendees will be able to explore how Sigmetrix can help them maximize the return on their MBD/MBE investment as well as delivering more innovative products through mechanical variation management.

          MCKINNEY, Texas – April 13, 2023  Sigmetrix, global experts in mechanical variation management announced that they will be at COExperience being held on April 17-19 at the Hyatt Regency Miami in Miami, FL.

          COExperience helps users and their company leverage their Dassault Systèmes solutions through education, training, networking opportunities, product influence and best practices available exclusively to COE members. The Sigmetrix team is proud to be a “Silver Partner” for this show and will be at Booth 110 in the Technifair. Sigmetrix will demonstrate how their tools can help identify the problems or risks related to how variation is controlled in a design.

          There is a lot of discussion in industry about Model-Based Definition, Industry 4.0 and Digital Thread.  Many companies are starting down the path toward a Model-Based Enterprise, but that path can be challenging. There are many facets to becoming truly Model-Based, but as the name implies, the key is the models themselves and their connections to various parameters.  It is important that all requirements be tied directly to this comprehensive set of models to ensure traceability and usability. One set of requirements that is critical to the quality of any product is its dimensional requirements that are used to control mechanical variation. Sigmetrix, with its knowledge of managing mechanical variation, can help maximize the return on your MBD / MBE investment in the following ways:

          • Ensure the integrity of your MBD to maximize usability.
          • Guide the creation of optimal dimensioning schemes, including GD&T.
          • Promote consistent knowledge between contributors and consumers.
          • Assess and improve the maturity of your organization’s Mechanical Variation Management.

          Traditional views on the management and understanding of mechanical variation have stifled innovation in some companies and limited them to only developing derivative products. The best-performing companies see how a consistent understanding of mechanical variation throughout an organization and the ability to quickly simulate sensitivity to variation in concepts leads to more innovative, breakthrough products.​

          Sigmetrix has been Dassault Systèmes Gold Partner since 2002 with CETOL 6σ for CATIA V5-6. CETOL 6σ couples the power and functionality of Dassault Systèmes’ CATIA parametric design capabilities with precise calculations and advanced mathematical technologies.

          Attendees will want to make sure to catch Stephen Werst, Director of Customer Success, and Product Strategy, present “Mechanical Variation Management – An Engineering, Manufacturing, and Inspection Strategy Directly Influencing Product Profitability” on Wednesday April 19th at 9:10AM EST.

          “Many companies today still consider tolerance analysis as the final analysis activity performed on the design before it is released to manufacturing. Unfortunately, some don’t allot enough time in the design process to perform the necessary studies, or, even worse, knowingly opt not to perform them and release the models and/or drawings with the expectation that problems occurring during the first production runs will be fixed as they occur. Such approaches usually lead to excessive, and often hidden, costs that erode profit margins over the life of the products,” states Stephen Werst, Director of Customer Success, and Product Strategy.

          In addition to demonstrating CETOL 6σ at their booth Sigmetrix will be showing off their entire portfolio of comprehensive, easy-to-use solutions including:

          • EZtol, a 1D analysis tool designed to make it easier to create, manage and report upon multiple 1D tolerance analyses in an assembly.
          • Training provided through more than a dozen instructor-led and computer-based courses covering basic to advanced GD&T/GPS, MBE, and MBD
          • Consulting and implementation services with years of experience in tolerance analysis and GD&T definition offer a variety of consulting services to augment your team, speed your project along and run analyses for your assemblies.
