          Sigmetrix To Sponsor LiveWorx 2023 in Boston, MA

          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 deliver more innovative products through mechanical variation management.

          MCKINNEY, Texas – May 11, 2023  Sigmetrix, global experts in mechanical variation management, announced that they will be “Showcase Sponsors” at LiveWorx® being held May 15-18 at the Boston Convention and Exhibition Center in Boston, MA in Booth 902.

          At LiveWorx 2023, there will be a strong emphasis on learning, connecting, and engaging with one another. Expect important PTC®­­ strategy and product updates, digital transformation thought leadership, tips, and tricks on how to get the most value out of your PTC products, training opportunities and inspiring stories from our customers and partners. In addition to educational programming, there will be many opportunities to network, see technology come to life with innovative tech demos and create memorable experiences together.

          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 a PTC Partner since 1999. During this time, Sigmetrix has provided the PTC market with the best-in-class tools for tolerance analysis.  One of these tools is Creo EZ Tolerance Analysis Extension. This tool allows engineers and designers to quickly define multiple 1D stack-ups within PTC Creo. This will enable an engineer or designer to easily assign appropriate tolerances within their parts.

          Attendees will want to make sure to catch Ross Snyder, Applications Engineer, present “Tolerance Analysis with EZTA & CETOL: More Reasons to Stop Using Spreadsheets” on Tuesday May 16th at 3:30PM EST in the Xtropolis.

          “We are excited to continue our strong partnership with PTC. PTC has shown their commitment to us by embedding both our GD&T Advisor and our EZtol technology into PTC Creo to augment its MBD capabilities,” commented James Stoddard, CEO & President of Sigmetrix. “These tools along with our CETOL product provide a complete solution to help companies build better products through variation management. Creo EZ Tolerance Analysis Extension provides a bridge between performing manual tolerance stackups and using more advanced tool like CETOL 6σ.”

          At their booth, Sigmetrix will be showing off their entire portfolio of comprehensive, easy-to-use solutions including:

          • CETOL 6σ, a fully integrated 3D tolerance analysis solution
          • 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 team 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.
