In this paper, the influence of hard coatings (nanolayer AlTiN/TiN, multilayer nanocomposite TiAlSiN/TiSiN/TiAlN, and commercially available TiN/TiAlN) and cutting parameters (cutting speed, feed rate, and depth of cut) on cutting forces and surface roughness were investigated during face milling of AISI O2 cold work tool steel (∼61 HRC). The experiments were conducted based on 313 factorial design by response surface methodology, and response surface equations of cutting forces and surface roughness were obtained.

This article presents the results of turning hardened and normalized bearing steel AISI 52100 (DIN 100Cr6), comparing conventional flood and dry with cryogenic machining. Turning results show drastic improvements in tool lifetime (up to 370%) for cryogenic machining of normalized bearing steel 100Cr6 and reduction of thermal residual stress inducements in case of hardened bearing steel 100Cr6, while tool life is also extended.

Crises are not necessary in productions and in selling market. Reasons are mostly in wrong state policy. Some solutions are brought by engineers with their deep knowledge in prediction technique. Paper presents some ideas how to save energy by prediction and ways of sustainable manufacturing.
