Creating an Efficient Geometrical Measurement Planning Process

摘要

The scope and purpose of this paper is to give input and propose solutions to the creation of an efficient and productive geometrical measurement planning process. The case study outline what is important and how to identify and determine the preconditions and input data which is required to start the preparation and planning activities of geometrical measurements. That is why the following three main research and development questions should be answered:Firstly; What is the need and why does an efficient and productive geometrical measurement planning process contribute to decrease cost upstream as well as downstream in terms of reduced lead times in measurement planning process work? Secondly; Why are reduced uncertainties related to geometrical; functionality, specification and verification, important? And how are they linked to each other and how can they be theoretically modeled and defined in terms of uncertainties? The last question is; How is the current geometrical measurement planning process constructed and what does it contain and how is it functioning? By applying a more systematic and holistic approach in product realization and measurement planning activities, the accomplished study indicates improvements and high potential for cost savings, from 3 up to 12 times. Hence the improvement potential is strongly dependent of the actual geometrical complexity level of the airframe assembly being studied. Results from this study will further improve and develop current applied geometrical measurement planning process and will contribute to a more effective and productive working methodology and process.
