CAPP Benefits

Important benefits can result from the implementation of CAPP. In a thorough survey of twenty-two large and small companies using generative-type CAPP systems, the following calculated cost savings were attained:

• 58% reduction in process planning effort.
• 10% saving in direct labour.
• 6% reduction in work-in-process.
• 4% saving in material.
• 12% saving in tooling.
• 10% saving in scrap.

Additionally, there are intangible benefits as:

• Greater process plan consistency; access to up-to-date information in a central database.
• Reduced process planning and production lead-time; faster response to engineering changes.
• More complete & detailed process plans.
• Improved cost estimating procedures and a little calculation errors
• Enhanced production scheduling & capacity utilisation.
• Improved ability to introduce new manufacturing technology and quickly update process plans to utilise the improved technology.
