RAS Reports and Case Studies

Autostamp is a SME specialising in sheet metal working for the automotive industry that has had long term collaborations with the University of Naples Federico II in the above mentioned fields. Autostamp recently submitted a technological enquiry regarding the identificaion of problems in micro feature characterisation in sheet metal products for car body parts.

Miba Sinter is a leading powder metallurgy company that has had long term collaborations with the University of Naples Federico II in fields of powder metallurgy manufacturing and related metrology aspects. Miba Sinter recently submitted a technological enquiry regarding the problem of micro fabrication through powder metallurgy and the metrological procedures to be applied in this field.

Ansaldo Breda is one of the world leading train manufacturing company that has had long term collaborations with the University of Naples Federico II in fields as diverse as metal processing, welding and brazing, advanced materials technology, metrology, nondestructive evaluation, material characterisation, etc. Ansaldo Breda recently submitted a technological enquiry regarding the establishment of appropriate metrology procedures for nondestructive characterization of micro features in insulated gate bipolar transistor(IGBT)assembly devices for the railways traction industry.

The company searched BUTE, that it would like to produce microparts at the University. The problem was that we had to produce very small pieces. The biggest diameter of parts was 1.6 mm, and the length was 4 mm. We had to do two bores in the pieces. One of bores was 0.5 mm, and the other one was 0.7 mm. And we needed to keep the serious tolerance, for example concentricity.
The University was dealing with similar workpieces. The our tasks were the choice of tools, determination of technology and definition of proper manufacture parameters.
