Project summary
Rolls-Royce are seeking to reduce costs and improve
operational efficiency in all areas. An area of large
cost within the design process is the creation of two
dimensional drawings to convey the definition
required to manufacture/inspect the parts to the
manufacturer. This report looks into how the cost and
lead time of this task can be reduced whilst still
adhering to regulations.

Project Objectives
Primary Aim
Reduce amount of definition on two dimensional
drawing.
Objectives
• Set limits to work within.
• Assess the influencing factors determining the
form of the drawings.
• Assess the feasibility of these main influences
changing.
• Assess the benefits of changing these influencing
factors.
• Compare the potential solutions.
• Define the best overall solution with associated
cost and time savings to build a case for changing
the current process.
• Pursue the implementation of the final solution.
Project Conclusion
Within Rolls-Royce processes and particular
constraints It is possible to reduce the amount of 2D
definition by approximately 35%.
This is achieved by:
• Implementing a ‘smarter’ drawing format.
• Change inspection method from CMM to GOM
scanning.
• Omitting irrelevant information.
