A Theoretical and Practical Approach to Geometrical Part Assurance

Metrology is the science of measurements; production engineering metrology is the science of applied metrology in production and in product realization. In this paper the automotive, construction equipment and aerospace industry are particularly addressed. One theoretical and practical approach to geometrical part quality assurance focusing on manufacturing processes and systematic work and use of objective, value adding production engineering metrology is proposed. This paper aims to describe a practical approach on how to carry out geometrical assurance of parts produced in manufacturing processes using traditional production methods. One example using machining, i.e. turning, of a part is used to explain this approach.
