CASE STUDIES

Phillips Plastics Case Study

PHILLIPS PLASTICS 

Phillips Plastics implemented CETOL 6 Sigma in their design process
for a drug delivery device. The end result was a more robust design,
improved product quality and reduced costs.

  
ZF Electronics Case Study

ZF ELECTRONICS

Engineers at ZF Electronic utilized CETOL 6 Sigma on their automotive
door latch assembly, identifying design areas that were sensitive to
variation prior to entering production. The end result was substantial
cost savings and time-to-market benefits.

  
Mechanical Variation Software 

MECHANICAL VARIATION SOFTWARE

This customer used CETOL 6 Sigma to manage mechanical variation
and perfect the cam-roller design for the delivery of its zero-degree
wrench to the professional and consumer market.

WHITE PAPERS

Cummins Engine Case Study

CUMMINS ENGINE - BRAZIL

Cummins Engine Brazil used CETOL 6 Sigma as a component of a
Dimensional Variation Analysis (DVA) it performed to verify the length of a
FEAD (Front Engine Drive Accessories) belt path. The results were used
to make improvements in the assembly line and in the design itself.

  
Monte Carlo White Paper

MONTE CARLO WHITE PAPER

This paper explores a new second-order tolerance analysis (SOTA) method,
the development of which was motivated by the differences in capabilities
between the Linearized Method and Monte Carlo simulation of
tolerance analysis.

Functional Interface Based Assembly Modeling

FUNCTIONAL INTERFACE-BASED ASSEMBLY MODELING

The continuing market pressures for development and delivery of new
products faster, cheaper, and at higher quality are driving the need
for assembly models that not only provide information regarding both
design and manufacturing issues. This paper presents two key aspects
of an approach to assembly modeling that will support the extended
challenges today’s design and manufacturing environments.

 

  
GD&T-BASICS

WHAT IS GD&T? 

Geometric dimensioning and tolerancing and represents a way to
mathematically describe the size, location, orientation, and form of a
part feature, utiling a special set of symbols to define the relationships
between features.

  
Tolerance-Stack-Up4 

TOLERANCE STACK-UP 

Tolerance Stack-Ups are vital calculations used to address mechanical fit
and mechanical performance requirements. They represent the cumulative
effect of part tolerance with respect to an assembly requirement.

  
DFSS 

DESIGN FOR SIX SIGMA 

Design for Six Sigma (DFSS) is a customer-focused product development
attitude and methodology that effectively translates the Voice of The
Customer (VOC) into a robust design.

  
GEOMETRIC TOLERANCING3 

GEOMETRIC TOLERANCING 

Geometric Tolerancing is the art of applying GD&T. This paper illustrates
how using geometric tolerancing imparts a well defined control for the
variation of a part feature.

  
  

WHAT IS TOLERANCE ANALYSIS? 

Tolerance analysis is a name given to a variety of approaches utilized
in product design to understand how sources of variation in part dimensions
and assembly constraints affect capability of a product to meet customer
expectations.
