Western European Example of Defense Development

Abstract

It is particularly important for the French political leadership to maintain French independence, to develop military defense capabilities and to maintain a balance between budgetary constraints. The publication presents a European way of continuously modernizing the French army and modernizing its technical tools. France has one of the strongest and most powerful armed forces characterized by adapting NATO-based applications and procedures.

Difficulties in the Machining Super Duplex Stainless Steels

Abstract

Super duplex stainless steels are used in increasingly more areas. The machinability of duplex stainless steels is generally poor. We performed dry turning tests on G X2CrNiMoCuN 26-6-3-3 casted superduplex steel, using two different PVD coated cutting inserts. One of them was coated with TiAlN and other with TiAlSiN. Strong burr and built-up edge formation were observed during our machining experiments; these damaged the edges of the tools. The shortened tests did not show significant difference betwen the effect of the coatings.

High Feed Turning: Roughing and Finishing with the Same Insert?

Abstract

The tools of multi-directional machining, having appeared in the recent years, have revolutionised turning operations. The chip removal of high feed roughing and finishing inserts is so specialised, that new formulas have to be introduced instead of those used so far. In this paper, the result of tests carried out up till now will be summarised; furthermore, a proposal will be made on the description, analysis and calculation of force demand of multi-directional inserts as well as the roughness of the surface being prepared during machining.

Tools for Increasing Safety Awareness in Higher Education

Abstract

There comes a time in the life of every family when their child becomes an adult and sets out to put themselves to a great test: undertaking further studies in higher education institutions. But can we really use the word adult for these youngsters? Seen from a teacher’s point of view, we surely cannot: we see them every day, and it is obvious that they are still very much children. And if we think deeper, we can understand it, we too were once freshmen. When parents let their children go out into a world that is yet unknown to them, the most important concern is their safety. Security consciousness is appearing in many places in higher education. Getting to the school, living in hostels, the rent, the whole environment, the list is endless. But we should mention something that has become an integral part of the new world, which is freedom, and the lack of parental control. Many simply cannot handle this and get carried away, some people just can’t say no to a friend’s invitation. And there is yet another serious source of danger; the Internet. Social media pages, email accounts, video sharing channels, etc. that keep appearing and refreshing. All are potential sources of attack, and if we don’t have sufficient means of protection, youngsters can easily fall prey.

Chip Removal Specialities in Multi-Directional Turning

Abstract

For machining of increasingly complicated geometries, the longitudinal and transverse turning operations should be performed with a single tool. Leading manufacturing companies have developed a number of constructions. The world’s largest manufacturer has recently revolutionised turning by launching roughing and finishing tools. The roughing insert can work with “high feed turning” in four different directions of movement. This tool has a unique chip forming and removal, it forms a unique machined surface. This study gives an overview of the results achieved in this area.
