- 26. 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
- 27. 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
