Agenda
Introduction
Current situation of Geometry assurance at Powertrain GTT
Why Powertrain GTT is looking for new Geometry Assurance process?
Variation Simulation on a case study and its benefits
Suggested Geometry Assurance process for Powertrain GTT
Benefits of implementing the suggested Geometry Assurance process
Challenges
How to choose a robust solution?
How to do right from beginning?
How to predict variation?
How to reduce
geometrical variation?
How to reduce cost from idea to market?
How to smooth the way from
design to production?
Major contributors of variation?
How to improve product quality?
Tolerances acting in Pipe in actual design
Major contributor : Tolerance acting point MP = 2mm
New design suggestion and tolerances
Assumed Tolerance acting at point MP = 1mm
Current Phase of Geometry Assurance at Powertrain Volvo GTT
Current phase of Geometry Assurance in powertrain
GTT
No systematic process for Geometry Assurance
Primary focus on Functional requirements
Bottom-up approach in tolerances
No flow of data from production
Experience matters Tools like
CTOL, Excel, RD&T are used
RD&T used by three
engineers
Worst Case and RSS are mostly used
Monte Carlo used on critical
requirements
Why Powertrain Volvo GTT is looking for Geometry Assurance implementation?
Why Volvo Powertrain
needs Geometry
Assurance?
Awareness about
tolerances
Shorten lead time from project to product
Reduce physical
prototypes
Share common database
Improve supplier
interaction
Involve manufacturing
engineer in concept phase
Attain functional
requirements with max
quality
To choose robust solutions
To choose manufacturing
processes virtually before
production

Benefits of implementing Geometry Assurance
Benefits
Robust solutions
Having control over process
Problems can be fixed in
design
Less adjustments in production
Having cross functional team helps in taking good decisions
Reduce redoing of
things
Defining locators and requirement breakdown
Supplier relation
gets stronger
