Industry Applications – Automotive
Application – Injector Axis
Objective: CETOL 6σ used to the design change required to shorten line for injector axis and to represent true length of feature.
Application – Manifold Seals-V Block Engine
Objective: CETOL 6σ tolerance analysis software was used to evaluate clearance between critical features for head assembly and manifold sealing surfaces
Challenges:
– Highly non-linear assembly problem
Application – Door Latch Assembly
Objective: See if application of CETOL 6σ software would shorten analysis time and save money
Issues:
– Up to 60 hours per design on simple stack-up analyses. Conservative in tolerance application
– Multiple prototype iterations costs thousands of dollars and meant numerous weeks added to production time
– Door latch mechanism could potentially send a signal to the instrument panel that the latch on the door was locked when it was not; significant safety concern
Objective: Ensure correct performance of gearbox and beat competitors to market with a more innovative, higher-quality product
Results: CETOL 6σ allowed the customer to analyze the shift mechanism in a 1/3 of the usual time. Able to predict of failure modes, correct application of GD&T and improved design confidence
