          Deliver Better Products With CETOL 6σ Model-Based Variation Simulation

          Sigmetrix’s tolerance analysis software works directly with the data files from the leading CAD solutions to provide comprehensive 3D model-based tolerance analysis.
          KEY FEATURES OF CETOL 6σ

          Accelerate Tolerance Analysis & Learn How Variation from Multiple Sources Impacts Critical Performance Characteristics of Products

          CETOL provides invaluable insights to the impact of part and assembly variation using advanced mathematical solutions, enabling designers and engineers to easily address multi-dimensional problems within their native CAD environment.

          • Achieve a clearer understanding of how your design reacts to real-world variation and proactively fix issues with sensitivity plots and visualization tools that highlight the impact of each source of variation on the design.
          • Contribution plots identify where best to invest in more expensive processes needed to achieve specific product requirements as well as where tolerances may be relaxed to reduce costs by being able to use less expensive manufacturing processes.
          • Optimize designs quickly with models that immediately update to reflect changes to tolerances or statistical distributions via CETOL’s unique mathematical algorithms.
          • Answer pressing technical and business questions during both design and production phases with data presented in customizable, tabular formats.
          • Communicate critical-to-quality tolerances and other business conclusions across the enterprise with comprehensive, customizable reports.
          • Enjoy an intuitive, easy-to-use interface and logical workflow guided by the Advisor to obtain results and improve your designs as efficiently as possible
          • Use the Advisor to quickly identify and correct potential issues with the variation model and gain confidence in the accuracy of the predictive model
          • Get in-system reminders and tips with context-sensitive instructional videos that reinforce how to properly use the tool.
          • Quickly identify each item in the analysis with highlighting in the CAD graphical window when the item is selected.
          • Works directly with your CAD files without data conversion to ensure the analysis results immediately reflect the changes occurring to your designs
          • Easily integrate CETOL data with other systems using open data export and storage formats, such as XML, CSV, and HTML.
          • Utilize standardized variation models for future design iterations to improve analysis efficiency.
          SAVE COSTS AND INCREASE EFFICIENCY

          ENHANCE MECHANICAL VARIATION MANAGEMENT

          Reduce Rework, Scrap, Prototype Builds, and Engineering Changes

          When you use CETOL for fully integrated 3D tolerance analysis, you reap benefits beyond just the software user—deploy better products, save costs, and increase efficiency across the enterprise. 

          • Avoid rework by working directly in your CAD files, where design changes are automatically reflected in your tolerance studies without recreating the analyses.
          • Optimize designs quickly without rerunning time-consuming simulation cycles each time an input parameter change.
          • Achieve a better understanding about how your design reacts to real-world variation and identify and resolve potential problem areas before they are found in manufacturing or by your customers.
          • Control costs by starting with tolerances that are the least expensive to manufacture, then have CETOL guide you on where to invest in more expensive processes needed to achieve specific product requirements.
          • Use the Advisor window to see flags for potential issues, and gain confidence that nothing has been overlooked in defining the analysis or dimensional requirements.
          • Assess data in tabular formats and customizable reports and share it across the enterprise for shared understanding.
          • Store and export CETOL data in open data formats to easily integrate it with other engineering analysis or quality systems.
          • Create custom templates of analysis definitions to work more efficiently and dynamically when making adjustments to new designs.
