Abstract: The design of a certain workpiece lies mainly in its functionality. Nevertheless, in most cases the design of the workpiece has to be adapted to the characteristics of the manufacturing process, taking casting as the most representative example. Surprisingly, dimensional verification is kept out of the design, increasing in some cases substantially the final cost of the workpiece. In this paper, the friendliness between the design and the verification is evaluated. The main concerns in dimensional verification: sampling strategy and uncertainty are addressed. Additionally, cost in terms of equipment and time is covered. Four illustrative cases, on the same workpiece design, are used to explain the method, benchmarking each of them in an Efficacy and Efficiency scale. For each, suggestion regarding workpiece design and process design are made in order to improve the final result of the benchmarking.
