Dimensional Variation Analysis

Dimensional Variation Analysis

Dimensional Variation Analysis – To set the tools and methodology for improving dimensional quality consistency And the cost effective process by managing and controlling dimensional variation to ensure a calculated design.

It was formed as a learning from different OEMs and its purpose is to optimize vehicle dimensional quality and achieve integrity on new vehicle programs.It is a part of advance process engineering and initial dimensional datum strategy to achieve car dimensional.

Require actions are systematically mapped at each project milestone to meet above objective.
