CETOL 6σ Features & Benefits

Why CETOL 6σ?  Features and benefits at a glance!

Key Features
Works directly with your CAD files – no data conversion required.Avoid rework. Design changes that inevitably occur will automatically be reflected in your tolerance studies – no need to fix, or worse, recreate the analyses.
Changes to tolerances or input statistical distributions immediately update the results.Optimize the design quickly without having to rerun time-consuming simulation cycles each time an input parameter changes.
Sensitivity plots and visualization tools highlight the impact of each source of variation on the design.Achieve a better understanding about how your design reacts to real-world variation. Identify and resolve potential problem areas before they are found in manufacturing or by your customers.
Contribution plots show what dimensions and tolerances are driving the variation in the design objectives.Start with tolerances that are the least expensive to manufacturing and have CETOL guide you on where to invest in more expensive processes needed to achieve specific product requirements.
Advisor with 3 classifications of messages provides guidance on the next steps or items that should be reviewed by the user.Gain confidence that nothing has been overlooked in defining the analysis or in defining the dimensional requirements on your part drawings.
Analyzer presents data in customizable, tabular formats to assist in answering many common technical and business questions.Answer common business questions that arise during manufacturing such as:

  • Where is the best application of Statistical Process Control (SPC)?
  • Can we use this group of non-compliant parts or must we scrap them?
  • Which vendor will provide us the quality we need at the lowest cost?
Powerful context-sensitive help system with over 40 videos showing how to perform specific tasks.Start using the software again quickly after not using it for a long time.
Comprehensive and customizable reports.Provide just the right amount of information needed for your target audience to understand your efforts, conclusions, and recommendations.
Common, open data formats such as XML for storing the CETOL 6σ data and CSV and HTML for extracting other data from the analysis results.Integrate the CETOL data, including results and the data generated to obtain them, with other engineering analysis or quality systems.
Visual feedback for each item via Interactive highlighting in CAD graphical window when the item is selected.Quickly identify each item of the analysis with visual cues.
Analyses definitions can be saved as a template for application to next-generation designs.Leverage what you’ve learned from previous designs while maintaining a dynamic model to help you make adjustments needed for the new design.

CETOL 6σ Results

How Companies Use CETOL 6σ

Throughout the world, companies of all sizes and industries use CETOL 6σ when they need to understand the impact tolerances will have on a mechanical assembly. Based on survey results from our customers, here are some of the primary uses of this powerful tolerance analysis tool.

Reduce Costs
Supplier A is 10% cheaper than supplier B but supplier A wants a wider tolerance. Can you choose supplier A? Only with CETOL 6σ can you know the impact that the tolerance change will have on the overall assembly – helping you drive to a lower per part cost.

Scrap is reduced when you know whether or not parts that arrive from a supplier can or cannot be used in the assembly. Production delays are avoided when you know the impact that changes will have to the overall assembly.

Increase Productivity
CETOL 6σ puts better information in the hands of the decision makers. Engineering Change Orders (ECO’s) can be reduced and you can focus on what is important. With CETOL 6σ, you can quickly see problem areas and simplify inspections by knowing what parts are critical to quality.

Impact the Overall Business
Too many times, recalls and warranty issues are caused when good designs are lacking a thorough tolerance analysis. CETOL 6σ helps companies reduce warranty issues, field failures and product recalls by enabling you to perform a complete analysis in the same amount of time as a less than complete analysis could be done by hand. Customers today use CETOL 6σ to mitigate risk and reduce liability with detailed analysis and reporting.
