Pdes inc success stories
PDES, Inc. Success Stories

  • Company Implementations resulting from PDES, Inc. Pilots:

    • Lockheed Martin

    • Delphi Delco Electronics Systems

    • CSTAR

    • Boeing PowerSTEP/AEROSTEP

    • GM STEP Translation Center

Success story lockheed martin
Success Story:Lockheed Martin

  • STEP is being used to support the F-16, F-22, Joint Strike Fighter, F-2 and KTX-2 programs at Lockheed Martin

  • Lockheed Martin is pioneering the STEP standard with smaller businesses that are its supply base

  • STEP has realized significant savings and process improvements

    • Within engineering design, pilots show a 10% improvement in reliability of data exchange, 10% process savings for non-composite parts, and 50% process savings for composites

    • For manufacturing, projected savings for tool design on CAD/CAM systems is 27% and 38% for NC CAM systems due to elimination of data re-entry

Success story delphi delco electronics systems
Success Story:Delphi Delco Electronics Systems

  • STEP is being used in support of climate control systems for two major OEM customers.

  • All mechanical design at Delphi Delco Electronics Systems is accomplished using EDS/Unigraphics; the two OEMs require Dassault Systemes’ CATIA

  • Previously used IGES and recreation of solid models took three to five days per component

  • A recent example showed 12 files translated via STEP; approximately 50 hours were saved by eliminating virtually all manual intervention

Success story cstar
Success Story:CSTAR

Development of electronic data exchange capabilities between C-17 facilities in Long Beach and St. Louis using STEP . Boeing’s McDonnell Douglas unit is now using STEP in production to exchange C-17 configuration management data on a daily basis.

  • Significant Cost and Schedule Improvements -- manual method was error prone, slow (3 weeks to 2 months; now overnight), and people intensive (3 people full time; now zero)

  • Expanding capability to use OMG CORBA and SDAI for on demand update/viewing of electronic engineering order system

  • Participants:

    • Boeing’s McDonnell Douglas unit - ITI

    • Northrop Grumman - IBM

Success Story:AeroSTEP/PowerSTEP

Show viability of STEP as an exchange mechanism supporting Digital Pre-Assembly (DPA) of engine/strut interface.

  • STEP is being used in production between Boeing and their three engine manufacturers for the DPA process on the 777 and 767-400 Extended Range Programs

  • STEP will be the preferred process for future Boeing programs

  • PowerSTEP won 1997 CALS Implementor Honor Roll Award

  • Participants:

    • Boeing - GE

    • Rolls-Royce - Pratt & Whitney

    • Dassault Systems - Computervision

    • EDS Unigraphics

Success Story: STEP Translation Center

  • STEP is used to transfer product designs between GM divisions, their customers and suppliers

  • Production operations of STEP Translation Center (STC) began May 1, 1996

  • Initial focus was translation of solids between UG and CATIA using AP203; additional CAD systems are in testing

  • GM has performed detailed IGES/STEP testing which has resulted in plans to phase out the use of IGES

  • First GM divisions to use STC:

    • Delphi Automotive Systems

    • GM Powertrain

    • Delphi Delco Electronics Systems

Pdes inc pilots step web integrated supplier exchange stepwise
PDES, Inc. Pilots: STEP Web Integrated Supplier Exchange (STEPwise)
