P13458: Dresser-Rand Compressor Assembly Line Team Members: Lauren Kraft Project Manager, Nick Feng IE Cole Bowden ME, Shawn Moseley ME Jordon Boggs ME, Alex Peterson ME Preliminary Detailed Design Review Phase I: Assembly Stations 1-5 Slide 2 Agenda Key Objectives of this Review Problem Statement Preliminary Detailed Design of Caster System: Caster Design Cart Design Universal Frame Interface Frame and Caster Plate Stress Analysis Design Risks Identified Detailed Design Needs Ergonomic Justification Process Layout Update Economic Analysis Project Outlook & Timeline Slide 3 Key Objectives of this Review Prototype DesignOverall Process layout Catch mistakes Improve design from operator feedback Specs (needs) are addressed Risks are addressed Decisions are made to further design Receive feedback on current layout Consider alternatives and application of lean principles What are we missing? Slide 4 Problem Statement Design a flexible material handling system to incorporate 5,000 to 22,000 pounds that is easy to use and incorporates the safest design elements within cost and functionality constraints. This design fully supports the new process layout in Dresser- Rands strategic project.
