Sustainable production as a global word, content important elements on all the fields as well as machining processes. Machining can be performed either on conventional or nowadays modern CNC way. Novel machining processes are based on CNC programmable technologies containing elements as CAD, CAM, etc. To define sustainable production as the creation of(More)
The samples of hazardous aluminum solid waste such as dross were physically and chemically characterized. A relationship between density, porosity and metal content of dross was established. The paper also examines the chemical reactions involving aluminum dross in landfill and the negative consequences. To avoid environmental problems and to recovery the(More)
High Performance Manufacturing (HPM) technology comprises new developments to reduce primary process times and lead times significantly by the means of enhanced cutting abilities, adapted tooling and machine concepts combined with integrated examination and optimization of the process chain. The overall objective of High Performance Manufacturing is to(More)
Contemporary cutting tools used for High Speed Cutting (HSC), made on the basis of micro-grained cemented carbides with multi-layer protective coating, allow for effective machining of hardened and tempered steels of hardness over 50 HRc. The characteristic wear of such tools is affected by the fact that the cutting speed is no longer the main influential(More)
A simple method with high efficiency for generating high pure hydrogen by hydrolysis in tap water of highly activated aluminum dross is established. Aluminum dross is activated by mechanically milling to particles of about 45 μm. This leads to removal of surface layer of the aluminum particles and creation of a fresh chemically active metal surface. In(More)
