Methodology to describe the influence of manufacturing processes on the part functionality

The performance of a value-adding process chain is significantly characterised by a stable and function orientated interaction of its manufacturing processes. To achieve this, it is necessary to define manufacturing tolerances for the significant work piece properties and to produce these tolerances safely. The allowed tolerance ranges are primarily defined by the functionality of the entire part. Thereby, not only macro- and micro-geometrical work piece properties are being tolerated in dependence of the part functionality, but also properties of the rim zone, magnetical properties, optical properties (e.g., reflection) and physical material variables. Within the process chain, these properties and manufacturing processes are interacting, but not all work pieces and process properties have direct influence on the final part functionality. Rather, they are only affecting parts of the process chain. Respectively, in the following a methodology to analyse, evaluate and describe the influence of manufacturing process properties on the final part functionality is described.
