This two part paper presents general issues, methods and a case study for achieving production sustainability on a machining technology level. In order to tackle these issues, the paper promotes sustainable production via the alternative machining technologies, namely cryogenic and high pressure jet assisted machining that have a high potential to cut costs and improve competitiveness by reducing resource consumption and thus creating less waste.

Machining experiments were performed using coated carbide tools at cutting speeds up to 160 m/min. The cooling capabilities are compared by monitoring of chip breakability, process regions of operability, cooling efficiency, tool wear, tool life and cutting forces. Test results showed that dry cutting could not be performed due to long and ductile chips that were formed for all investigated cutting conditions.

Titanium alloy (Ti-6Al-4V ) has properties like outstanding corrosion resistance and very good biocompatibility whicht makes this material very interesting for biomedical applications. Due to its material properties titanium alloy poses a challenge for machining operations. A sound understanding of the alloy behaviour during the machining process is essential to achieve shape and dimensions tolerances of the product with minimum costs and machining times.

The abrasive flow machining (AFM) represents a very efficient sustainable polishing process. Basically, the AFM is suitable for finishing of both external as well as internal surfaces. However, the efficiency of the AFM process depends on a number of factors, which can be classified in three groups, namely, the polishing media factors, the AFM machine factors and the workpiece factors. One of the major problems in the AFM process is to determine the relationship between these factors and the process results, i.e., the workpiece surface roughness or the changes in geometry of workpiece.
