CETOL
6σ is a comprehensive dimensional analysis
system used to support robust product development
processes from design through manufacturing. CETOL
6σ is built on 3D Variation Behavior ModelingTM
Technology fully integrated with CATIA V5, Pro-Engineer
and Solid Works which allows unique sensitivity,
statistical and worst case tolerance analysis. The
CETOL 6σ analyzer module allows for rapid ‘what-if’
studies, an integrated process capability library,
and powerful reporting tools. CETOL 6σ supports
full CAD integrated data management saving data
directly on the CAD model. CETOL 6σ is providing
the ease of use necessary to support the most complex
assembly models and analysis needs.

Benefits |
|
| |
Sigmetrix has streamlined the mechanical variation
modeling process and enabled users to get answers
early and often. Reductions in rework, scrap, and
engineering changes are common results of proper
CETOL implementation. Additionally, customers are
experiencing greater confidence in transitioning
products from the Design Phase to the Pre-Production
phase. Prototype build reductions of 50-75% are
common, resulting in fewer last minute changes,
which are often very costly.

Design Requirements with Manufacturing Realities |

This
diagram illustrates the basic phases of product
development. Traditionally, tolerance analysis was
only performed once in the life of a product because
the procedures were very computationally intense
and time consuming with results made unreliable
from inappropriate or incomplete data. CETOL has
maintained a very flexible, yet comprehensive modeling
approach that allows analyses to be conducted concurrently
with the product development process.

CETOL
can check a design’s feasibility even
before any 3-D solid geometry is created.
Through the use of simple CAD modeling entities
such as planes, lines, curves, and surfaces,
sensitivity data can be calculated and inexpensive
changes to the design or assembly constraints
can be implemented.
Functional
assembly modeling captures all possible sources
of variation and describes the physics of
how these variations affect the assembly specifications.
Modeling assembly variation is accomplished
by the user selecting true assembly contact
surfaces within the CAD environment.
CETOL
directly uses the FTA dimension scheme callouts
for each part in the assembly. The Part
Model Graph interface simplifies the part
re-scheming with “drag & drop”
functionality resulting in a logical part
dimension diagram.
The
last refinement of the CETOL assembly variation
model is to define part process definitions.
Utilizing CETOL’s Process Library, true
manufacturing variation can be assigned. Combined
with physical assembly constraint behavior,
a true virtual prototype is now ready for
review.
