Job Description Justification Train and car level geometrical performances (final customer requirements, functional requirement, assimilability, …) Specify tolerances so that the train set respects infrastructure constraints, and the cars respect train set constraints Clarify with Method the assembly process involved with critical characteristic Provide stack-up calculations to justify achievement with the needed tolerances linked to functional requirements Help the engineer to find an agreement on the needed tolerance DMTR, layout verification, AD1 definition, interface documentation & specification The enhancement of knowledge (tolerancing standard language, isostatism definition, assy loop, cascade of requirement…) The constitution of ready to use templates (tolerancing processes, stack up, pattern hole calculation, isostatism & interfaces)The end to end critical characteristic process DMTR, layout verification, AD1 definition, interface documentation & specification The enhancement of knowledge (tolerancing standard language, isostatism definition, assy loop, cascade of requirement…) The constitution of ready to use templates (tolerancing processes, stack up, pattern hole calculation, isostatism & interfaces) The end to end critical characteristic process
