Collaborative Engineering

Collaborative Engineering

• CAD Software Used
• Three subassemblies were modeled in three
  different CAD environments

• Collaboration Over Web-Portal
• TeamCenter portal was used during this project
  for data sharing.

• Why Collaborative Engineering?
• A global working environment has changed
  interaction among design and manufacturing
  engineers.
• The companies that work on the same project are
  often times located in different and far apart
  locations.
• Engineers design and manufacture products in
  globally distributed environments.
• Product data related to all stages in a product
  lifecycle design, manufacturing, assembly,
  service has to be consistent across all the
  entire chain.
• Application of web portals in keeping track of
  data and information helps in achieving high
  quality product through timely engineering
  communication.
• The portals support sharing of files from
  different CAD systems which can be subsequently
  integrated in the final assembly.
• Not all neutral exchange data formats have the
  same results (geometry can be lost).

• Switch and batteries - SolidWorks
• Power train UGS NX
• Housing CATIA (Generative Shape Design)

• The future engineering teams will work in a
  web-based collaborative environment, where
  designers, process planners, manufacturers, and
  even clients can communicate and coordinate their
  activities through web portals.
• Some of the key things, learned from this
  project are
• Proper definition of user rights and training
• Proficiency in different CAD packages
• Timely project updates and changes
• Packaging should be done last (it needs geometry
  from
• all other subassemblies)
• The software for assembly should be the same as
  for
• the base structure and housing.

• The final assembly has been made in SolidWorks
  and CATIA.
• STEP neutral exchange format has been used for
  data exchange among different CAD systems.
• IGES data exchange format created some errors in
  geometry conversion (lost surfaces, some
  subtracted solid have become added solids).

• Reverse Engineering of a Drill
• Collaborative design on a reverse engineering
  project.
• Product 3/8" 7.2V Cordless Drill
• Brand Name KRAFT tech, type CDP02CN-1
• Product has been divided in 3 subassemblies
• Switch and batteries
• Power train
• Housing
