Sigmetrix’ safety and security systems customers utilize our CETOL 6σ and GD&T Advisor software solutions to address multi-dimensional problems, using the modeling, analysis and reporting features.

Application – Door Lock

Objective: Determine design issues with door lock sets

Results: CETOL 6σ analysis determined that assembly nominal was off target. Sensitivity revealed and used to adjust the tolerances and further increase the yield. Engineer quickly recalculated part nominal to re-center assembly nominal. Tolerance values of top contributors quickly adjusted to reduce scrap and rework.
