In the first step information was collected regarding errors that might occur in the measurement process, their effects as well as error prevention and detection methods. The paper also includes the improvement measures undertaken, their implementation, the risk index reevaluation method and the communication of obtained results.

The problem that arises is to choose the optimal variant when existing equipment allows you to choose between two or more possible strategies. This article studies four types of strategies for precise holes finishing and establishes the advantages and disadvantages of each, considering two variables: precise holes quality and the strategy cost. Key words : cutting, finish boring, helical finishing, reaming,

Growing and managing an IP portfolio may have a strong impact on the economy. The technical universities, which possess a huge knowledge pool, are in a key position to provide a positive contribution in this respect. In the present publication some proposals are made and possible contributions are outlined.

It can be used to rapidly prototype a part with a decent precision. This paper analyses this possibility for a gas regulator that was cut in half. From the pictures taken of the part, a point-cloud can be generated that can be transformed in a mesh and subsequently in a CAD model. Alternatively, it can be compared with an existing CAD model to determine deviations.

One such trend that has greatly impacted the manufacturing industry is called Industry 4.0 and is regarded as the fourth industrial revolution. In this revolution one important aspect is that of quality. This paper makes a comparative study between tactile and optical measuring machines in the context of Industry 4.0. As the manufacturing industry must be more flexible and solve problems in a timelier manner, it is important to identify the right technologies appropriate for quality control.

In order to offer support for research and innovative developments we implemented a platform that manages information contained in patent repositories. The platform assures functionalities for information retrieval, content harvesting, patent repository administration and domain specific ontology management. The platform has also an eLearning component that teaches the students the steps of patenting an innovative idea. The platform offers support for gathering and preserving experience for research teams. This experience is benefic mainly for new researchers and PhD students.

E-DETECT is useful in the training and service activities carried out by the companies that produce industrial tomographs or use them for applications, because it gives the customer the possibility to witness the power of the new technology.

It follows the steps of the analysis process and presents the documentation used with the purpose of underlining the particularities of applying this kind of analysis to a measurement process. Key words : FMEA, measurement process, DAMIC model, CMM, risk analysis.
