Industry Applications – Consumer Products

In the consumer products industry, warranty issues and product recalls are always in the back of designers and manufacturers’ minds. Improving the design and manufacturing processes helps ease those worries.  An effective tolerance analysis study helps ensure that the specifications mandated during the design phase will work down the line in manufacturing, and that the end result  – the product, will not only satisfy the consumer’s needs but will do so for the required amount of time at an effective cost.

Application – Printer Cartridge Assembly

Objective: To utilize the 3D model to prototype a digital mockup and help mechanical designers to realize their design concepts

Results: 2D tolerance calculations without CETOL 6σ are not sufficient, and using it in the design concept stages helped designers to recognize potential problems and to produce a better design.


Application – Cellular Phone








Objective:Focus on fit and finish issues, with over 200 measurements addressed. Original 1D analysis not sufficient.

Results: Utilized CETOL 6σ for CATIA to properly analyze tolerances.



Application – Camera Focus Assembly

Objective: The robustness of  CETOL 6σ to handle more complex assemblies was critical in order to analyze the mechanical alignment in the zooming process.  The helical cam was having fit issues when turning with the assembly and it was the most sensitive to the overall assembly.

Results: Sensitivity analysis only way to understand the details of the assembly behavior, guiding the engineer through multiple sub-assemblies.
